How do oxygen enters the blood in the lungs explain |
| Answer» \tGaseous exchange takes place within the lungs by diffusion from the alveoli to blood capillaries and vice versa. Alveoli in lungs are numerous and only one cell thick.\tAlveoli are surrounded by capillaries that are also one cell thick.\tBlood, dark red in colour flows from the heart through these capillaries and collects oxygen from the alveoli.\tAt the same time, carbon diox¬ide passes out of the capillaries and into the alveoli.\tWhen we breathe out, we get rid of carbon dioxide.\tThe bright red, oxygen rich blood is returned to the heart and pumped out to all parts of the body. | |

Explain the heart of human being |
|
Answer» Structure of Human Heart\tThe heart is a muscular organ covered by a double membrane called pericardium.\tThe pericardial fluid of the pericardium lubricates the heart.\tThe heart is divided into four chambers — two upper atria and two lower ventricles.\tThe inter-atrial septum separates the two atria and the inter-ventricular septum separates the two ventricles.\tThe atrium and the ventricle of each side are separated by the atrioventricular septum.\tSuperior and inferior vena cavae open into the right atrium.\tThe right ventricle opens into the pulmonary artery.\tFour pulmonary veins open into the left atrium.\tThe left ventricle opens into the aorta.\tThe opening between the right atrium and right ventricle is guarded by the tricuspid valve.\tThe opening between the left atrium and left ventricle is guarded by the bicuspid (mitral) valve.\tThe opening of the right ventricle into the pulmonary artery and the opening of the left ventricle into the aorta is guarded by the semilunar valves.Working of Heart\xa0The right atrium receives blood from the upper and lower body through the superior vena cava and the inferior vena cava, respectively, and from the heart muscle itself through the coronary sinus. The right atrium is the larger of the two atria, having very thin walls. The right atrium opens into the right ventricle through the right atrioventricular valve(tricuspid), which only allows the blood to flow from the atria into the ventricle, but not in the reverse direction.The right ventricle pumps the blood to the lungs to be reoxygenated.The left atrium receives blood from the lungs via the four pulmonary veins. It is smaller than the right atrium but has thicker walls. The valve between the left atrium and the left ventricle, the left atrioventricular valve(bicuspid), is smaller than the tricuspid. It opens into the left ventricle and again is a one-way valve.The left ventricle pumps the blood throughout the body through the aorta, which\xa0is the\xa0largest artery in the body. The walls of the left ventricle are the thickest among all the chambers. Hiii Hi |

Explain transportation in human beings |
| Answer» In\xa0humans transporation of oxygen nutrients, hormone and other substances to tissue, CO2\xa0to the lungs and waste products to the kidneys is carried out by a well defined Circulatory System. In lower organisms material is\xa0transporated\xa0by diffusion | |

How do organism obtain their nutrition |
|
Answer» Tanks tanisha Autotrophic\xa0organisms make their\xa0own food by a process called photosynthesis. Green plants, for example, manufacture sugar and starch from carbon dioxide and water using the energy of sunlight to drive the necessary chemical reactions. Heterotrophic\xa0organisms obtain their\xa0food from the bodies of other\xa0organisms. |

What is the nervous system? Explain with the help of diagram. |
| Answer» Receptors\xa0: Are specialized tips of some nerve cells that detect the in formation from the environment.Receptors are sense OrgansNeuron\xa0: It is the structural and functional unit of nervous system.Neurons\xa0(also known as neurones, nerve cells and nerve fibers) are electrically excitable cells in the nervous system that\xa0function\xa0to process and transmit information. In vertebrate animals,\xa0neurons\xa0are the core components of the brain, spinal cord and peripheral nerves.The primary components of the\xa0neuron\xa0are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that\xa0receive\xa0messages from other\xa0neurons), and synapses (specialized junctions between\xa0neurons).The axon (nerve\xa0fibre) transmits electrical signals from the\xa0cell\xa0body. The dendrites are branching fibres that receive electrical signals from other neurons. The shape of a neuron is determined by the job it does.Synapse\xa0:The point of contact between the terminal branches of axon of one neuron with the dendrite of another neuron is called synapse.? | |

What is w.r.t diabetes mellitus? |
| Answer» Diabetes mellitus\xa0(sometimes called "sugar\xa0diabetes") is a condition that occurs when the body can\'t use glucose (a type of sugar) normally. Glucose is the main source of energy for the body\'s cells. The levels of glucose in the blood are controlled by a hormone called insulin, which is made by the pancreas.\xa0The term\xa0diabetes\xa0is derived from Latin (originally Greek) and means “to go through or siphon,” referring to a large amount of urine produced by the kidneys. The term\xa0mellitus, in Latin, means “sweet.”\xa0Diabetes mellitus\xa0causes high blood glucose levels and glucose eventually spills into the urine. | |

State the principle of pinhole camera |
| Answer» A Pinhole Camera:A pinhole camera works on the principle that light travels in straight lines.The pinhole camera consists of a closed box having a small pinhole in the front and a translucent screen made of butter paper at the back which acts as a screen to receive the image of an object. The pinhole camera is used to view the images of various objects like trees and buildings, etc. Formation of image in a pinhole camera:A ray of light coming from the top point A of the tree passes through the pinhole in a straight line to form an image at point A’ on the screen. Another ray of light coming from the bottom B of the tree also passes through the pinhole in a straight line to form an image at point B’ on the screen. Each point on the tree AB forms its corresponding image on the screen between points A’and B’. The image A’B’ of the tree AB is produced on the screen.The working of a pinhole camera illustrates the property that light travels in straight lines.An inverted image is formed in a pinhole camera because the light rays coming from the top and bottom of the object intersect at the pinhole.Characteristics of the image formed by a pinhole camera:\tThe image in a pinhole camera is real and inverted.\tThe image in a pinhole camera is of the same colour as the object.\tThe image in a pinhole camera can be smaller than the object, equal to the object or bigger than the object depending on the distance of object from the pinhole camera. | |

Working of the pinhole camera? |
|
Answer» A pinhole camera is a simple camera without lens, in the shape of a box. One of the sides has a small hole and it produces an inverted image of the outside world at other side.The box should be painted black from outside and inside for better clarity.The object whose image is to be seen should be in bright light.Smaller the hole, sharper the image.Temporary black and white images are formed on the screen if a tracing paper is used. Permanent colored and black & white images can be obtained using photographic films instead of tracing paper. Hope It Helps You?

Why do acids have corrosive nature ? |
| Answer» Generally, metals are electro-positive elements meaning they are good electron donors. So, when an\xa0acidcomes in contact with a metal surface it undergoes de-protonation quite easily. Essentially, the metal-acidsystem forms a Redox couple. This oxidation of metals is the main cause for\xa0corrosion | |

When is thene an electric current in the conductor |
| Answer» An\xa0electric current\xa0is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the\xa0electric\xa0charge flows through a\xa0conductor, we say that there is an\xa0electric current\xa0in the\xa0conductor. In the circuits using metallic wires, electrons constitute a flow of charges.\xa0Current\xa0can\xa0flow through a conductor\xa0only when an\xa0electric\xa0field is established\xa0inside\xa0it. An\xa0electric\xa0field exists\xa0inside\xa0the\xa0conductor, as it is connected to the battery. Thus,\xa0current flows through\xa0the\xa0conductor. | |

Explain the colouring of sky ( blue n red) in simple words..... |
| Answer» Blue: blue color scatter most in day (sply. Noon) . Distance b/w sun and earth is less in noon so light has to travel less. As blue have shorter wavelength it travel in dayRed: at morning and evening distance b/w sun and earth is more (sun is at horizon ). So blue light spreads off and sky looks red. | |
