Human heart function

The heart circulates blood through two pathways: the pulmonary circuit and the systemic circuit.

In the pulmonary circuit, deoxygenated blood leaves the right ventricle of the heart via the pulmonary artery and travels to the lungs, then returns as oxygenated blood to the left atrium of the heart via the pulmonary vein.

In the systemic circuit, oxygenated blood leaves the body via the left ventricle to the aorta, and from there enters the arteries and capillaries where it supplies the body's tissues with oxygen. Deoxygenated blood returns via veins to the venae cavae, re-entering the heart's right atrium.

Of course, the heart is also a muscle, so it needs a fresh supply of oxygen and nutrients, too, Phillips said.

The cardiovascular system circulates blood from the heart to the lungs and around the body via blood vessels.

"After the blood leaves the heart through the aortic valve, two sets of arteries bring oxygenated blood to feed the heart muscle," he said. The left main coronary artery, on one side of the aorta, branches into the left anterior descending artery and the left circumflex artery. The right coronary artery branches out on the right side of the aorta.

During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.

double circulation is necessary in human beings because oxygenated and deoxygenated blood does not mix with each other functions of human heart first it transports many substances to the body II it is a pumping organ

Double circulationhelps to keep oxygenated and deoxygenated blood from mixing. Such separation allows a highly efficient supply of oxygen to thebody.

The main function of the heart is to pump the blood to all parts of body and the flowing of blood helps in taking the deoxygenated blood from all parts and then provide them oxygenated blood by the pumping of heart.

Structure of Heart:The heart is a muscular organ composed of 4 chambers; the left atrium and right atrium (pl. atria) and the left ventricle and right ventricle (pl. ventricles). The left and right sides of the heart are separated by a septum. The right atrium receives deoxygenated blood through the vena cava. After passing through the tricuspid valve, the right ventricle pumps this deoxygenated blood out through the pulmonary artery to the lungs. This is called the pulmonary circuit. Simultaneously, the left atrium receives oxygenated blood, from the lungs, through the pulmonary vein. Once this oxygenated blood passes through the bicuspid valve and into the left ventricle, it is pumped out through the aorta to the rest of the body. This is called the systemic circuit. Valves act to partition the atria from the ventricles but most importantly prevent the backflow of blood. Structurally, the left wall of the heart is thicker hence maintains a higher blood pressure compared to the right side of the heart. All in all, humans have a double circulatory system through which blood is pumped by the heart to supply cells of the body.

Function of Heart: The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

The correct development sequence is as follows:

Sporogenous tissue – pollen mother cell – microspore tetrad – Pollen grain – male gamete

During the development of microsporangium, each cell of the sporogenous tissue acts as a pollen mother cell and gives rise to a microspore tetrad, containing four haploid microspores by the process of meiosis (microsporogenesis). As the anther matures, these microspores dissociate and develop into pollen grains. The pollen grains mature and give rise to male gametes.

Balance withPhotosynthesis.Respirationis the antithesis to the process ofphotosynthesis, in which carbon dioxide and water are taken in by autotrophs, along with sunlight, to make glucose and oxygen.

Alpha particlesare released by high mass, proton rich unstable nuclei. The alpha particle is a helium nucleus; it consists of two protons and two neutrons. It contains no electrons to balance the two positively charged protons. Alpha particles are therefore positively charged particles moving at high speeds.

Beta particlesare emitted by neutron rich unstable nuclei. Beta particles are high energy electrons. These electrons are not electrons from the electron shells around the nucleus, but are generated when a neutron in the nucleus splits to form a proton and an accompanying electron. Beta particles are negatively charged.

Gamma raysare electromagnetic waves of very short wavelength and high frequency. Gamma rays are emitted by most radioactive sources along with alpha or beta particles. After alpha or beta emission the remaining nucleus may still be in an excited energy state. By releasing a gamma photon it reduces to a lower energy state. Gamma rays have no electrical charge associated with them.

Alpha and Beta particles are actually physical particles of matter. The Alpha is two protons and two neutrons, and consequently is relatively very heavy and slow and carries a double positive charge.. A Beta is simply an electron and has a negative charge. The Beta may be moving from very slow to very fast, and the speed is an indication of it's "energy level". Gamma Radiation is a true electromagnetic energy, and moves at or near the speed of light.

Alphas can barely penetrate anything, not even a piece of paper. Betas do a bit better but still can only penetrate a thin piece of aluminum. Gammas on the other hand can penetrate inches of lead and feet of most other things.

FitnessFitnessmeans the ability to perform physical activities. This includes discussions on the strength of your muscles, joints and ligaments; the state of your endurance; and the power in which your body is capable of moving. This does NOT mean “health.”A person who is fit may not necessarily be healthy, and a person who is healthy may not necessarily be fit. "Health" covers a wide array of components which are usually under the umbrella word, "wellness.""Wellness,"In essence, covers all areas of health: mental health, emotional health, physical health, spiritual health, social health, relationship health, and so on. Basically, these are all the different components in a person's life that can affect their overall "well-being."So when it comes to "fitness"... a person may be fit — be active, participate in sports, be able to lift weights, change the shape of their body, run, jump, and increase their cardiovascular capacity — but this does NOT mean that the state of their body, or their overall "well-being," is in good health.

Rainwater harvesting is the gathering, or accumulating and storing, of rainwater. Traditionally, rainwater harvesting has been practiced in areas where water exists in plenty, and has provided drinking water, domestic water, water for livestock, water for small irrigation and a way to increase ground water levels.

Not only does this recharging arrest groundwater depletion, it also raises the declining water table and can help augment water supply. The artificial recharging are becoming very important issues. It is essential to stop the decline in groundwater levels, arrest sea-water ingress, prevent sea-water from moving landward, and conserve surface water run-off during the rainy season.

Specco Treatment Inc. believes in the responsible management and design of systems that are functional and especially engineering designed to provide & comply with those purposes in a safety manner. Specco is proud of represent big companies like Cultec, Atlantis & Rainwater Harvesting in which each of them have the knowledge and experience that complement our vision with the environment and in this specific case, stormwater.

Cultec’s specialty is in below ground stormwater detention ponds. They work with both traffic rated ponds and non-traffic rated ponds. Cultec System is the only system that can be worked in more that one level of recharged chambers. This is a big advantage because the foot print of the pond can be reducing substantially.

Also, Cultec have a complete system compose of manifolds, feed connectors, recharger chambers, stormfilter, filter fabric and polyethylene linear. Not just your system will be good engineered designed it also will be more functional and effective than any other system in the market.

There are many types of systems to harvest rainwater. Notable systems are systems for runoff rainwater and rooftop rainwater harvesting system. The type used depends greatly on the purpose (domestic or industrial use) and to some extent also on economics and physical and human considerations.

Atlantis have innumerous alternatives that can meet any applications focused on the runoff or rooftop rainwater harvesting system. Some examples are their permeable paving or drainage cells and multi-functional D-Rain Tanks..Atlantis work with drainage cells both for runoff rainwater and rooftop rainwater applications.

Also, Atlantis have alternatives for the collection of rainwater below ground both no matter if it is for reuse or for drainage, both alternatives can be handle with the D-raintank products. All of this companies are independent of each other, however have the specially engineered systems in which we first believe as professional, effective and warranty us the excellent results that every of us expect.

As rainwater may be contaminated, it is often not considered suitable for drinking without treatment. However, there are many examples of rainwater being used for all purposes – including drinking – following suitable treatment.

Rainwater harvested from roofs can contain animal and bird feces, mosses and lichens, windblown dust, particulates from urban pollution, pesticides, and inorganic ions from the sea (Ca, Mg, Na, K, Cl, SO4), and dissolved gases (CO2, NOx, SOx). High levels of pesticide have been found in rainwater in Europe with the highest concentrations occurring in the first rain immediately after a dry spell, the concentration of these and other contaminants are reduced significantly by diverting the initial flow of water to waste as described above.

A mechanism can be used to send the initial water flow to waste, usually the first few liters. These are commonly known as ‘first-flush’ diverters, and are used to increase the chance that the large-particle residue that might accumulate on a collection surface is washed away from (and not into) the storage tank.

Such a system also compensates for the fact that the initial minutes of a rainfall can include airborne pollutants being washed from the sky (chlorination is needed), and likewise minimizes contamination of the captured supply. Simple but regular inspection and maintenance of such a device is usually necessary. The water may need to be analyzed properly, and used in a way appropriate to its safety.

Rainwater Harvesting provide all the necessary equipment for the design and creation of any individual, household and business systems that are interest in the reuse of rainwater ensuring that the water remains a sustainable resource safety for both human health and natural environment.

Depending on the application and conditions of the stormwater to be collected, they select the components that better fit the rainwater harvesting system. They can provide you with rain heads, water diverters, tank screen, water tank, insect proof screens, flap valves, tank overflow outlets, pump systems etc..

At the moment, 2 types of systems are generally used. These include home improvements and commercial systems. Both of these systems are known under the term water harvesters. In both cases, the system consists of a storage tank that as mentioned before can be provide by Atlatis, Cultec or Rainwater Harvesting, to store the water and piping (to guide the water in).

Additionally, extra pressuring equipment as pressure vessels, inline pump controllers or pressure sensitive pumps may also be required and can be provide by Rainwater Harvesting Inc. Finally, water purifying equipment as water-purifying plants, UV-lights or filtration equipment are sometimes (depending on local conditions) added to purify the collected water.

Atlantis also have a division named Atlantis Ultraviolet which is specialize as the name indicated, in ultraviolet systems for this application too. Specco also represent companies like Water Tech who also can provide you with alternatives for Filtration Equipments.

Depending on local circumstances, a gravity-fed system may already be enough to have a pressured water collection system. In the latter case, no pumps/pressure vessels are thus required to have a pressured system. In practice, gravity-controlled systems are usually created by placing the water harvester on an elevation (rooftops).

Solar pumps are great use for this type of systems, since they are fill the tank during day light and store kinetic energy that can be use all day long through saving electricity. For this you can also considered our Specco Renewable Energy division.

Rainwater tanks may be constructed from materials such as plastic (polyethilene) and concrete as well as fiberglass and stainless steel which are rust and chemical-resistant. Tanks are usually installed above ground, and are usually opaque to prevent the exposure of stored water to sunlight, to decrease alga blooms. Tanks may be covered and have screen inlets to exclude insects, debris, animals and bird droppings.

Rain harvesting method is a process by which we can save waterin this process the rainwater is collected through pipes and Is stored in pitsthis water can be used for plants and general uses

1.Nitrogenous BasePurines and pyrimidines are the two categories of nitrogenous bases. Adenine and guanine are purines. Cytosine, thymine, and uracil are pyrimidines. In DNA, the bases are adenine (A), thymine (T), guanine (G), and cytosine (C). In RNA, the bases are adenine, thymine, uracil, and cytosine,

2.Pentose SugarIn DNA, the sugar is 2'-deoxyribose. In RNA, the sugar is ribose. Both ribose and deoxyribose are 5-csrbon sugars. The carbons are numbered sequentially, to help keep track of where groups are attached. The only difference between them is that 2'-deoxyribose has one less oxygen atom attached to the second carbon.

3.Phosphate GroupA single phosphate group is PO43-. Thephosphorus atomis the central atom. Oneatom of oxygenis connected to the 5-carbon in the sugar and to the phosphorus atom. When phosphate groups link together to form chains, as in ATP (adenosine triphosphate), the link looks like O-P-O-P-O-P-O, with two additional oxygen atom attached to each phosphorus, one on either side of the atom.

The building blocks ofDNAarenucleotides, which aremadeup ofthree parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3). ... Adenine (A) and guanine (G) are double-ringed purines, and cytosine (C) and thymine (T) are smaller, single-ringed pyrimidines.

Not only is drinking and driving against the law, it's among the most dangerous things you could do. Alcohol inhibits your ability to think clearly, which negatively impacts your ability to pay attention and make safe driving choices. If the law isn't enough of a deterrent, a clear understanding of what can happen when you drink and drive could be enough to discourage this reckless behavior.
