Name the various parts of alimentry canal |
|
Answer» The alimentary canal is a long hollow tube which runs from the mouth to the **** . It includes several organs and glands that processes food.The major organs or structures that coordinate digestion within the human body include the mouth, esophagus, stomach, small and large intestine. Glands include liver and pancreas.Mouth-\xa0The mouth\xa0is a specialized organ for receiving food and breaking up large organic masses. In the mouth, food is changed mechanically by biting and chewing.\xa0Food is moistened by saliva.\xa0The saliva contains an enzyme called amylase, which digests starch\xa0into\xa0maltose. During chewing, the tongue moves food about and manipulates it into a mass called a bolus. The bolus is pushed back into the pharynx\xa0and is forced through the opening to the esophagus. Esophagus-\xa0The bolus of food moves through the esophagus by peristalsis Stomach - The stomach is an expandable pouch located high in the abdominal cavity. Layers of stomach muscle contract and churn the bolus of food with gastric juices to form a soupy liquid called chyme. The stomach stores food and prepares it for further digestion. In addition, the stomach plays a role in protein digestion. Gastric glands called chief cells secrete pepsinogen, which is converted to\xa0pepsin in the presence of hydrochloric acid.\xa0The pepsin then digests large proteins into smaller proteins called peptides. To protect the stomach lining from the acid stomach\xa0cells secretes mucus that lines the stomach cavity.Small intestine: The\xa0chyme enters from\xa0stomach to the small intestine. The three parts of small intestine are\xa0duodenum, jejunum and\xa0ileum. The inner surface of the small intestine contains numerous fingerlike projections called villi. Each villus has projections of cells called microvilli to increase the surface area. Most chemical digestion takes place in the duodenum. In this region, enzymes digest nutrients into simpler forms that can be absorbed. Intestinal enzymes are supplemented by enzymes from the pancreas. In addition, bile enters the small intestine from the gall bladder to assist in fat digestion.The enzymes functioning in carbohydrate digestion include amylase (for starch), maltase (for maltose), sucrase (for sucrose) and lactase (for lactose).For fats, the principal enzyme is lipase. Before this enzyme can act, the large globules of fat must be broken into smaller droplets by bile.Protein digestion is accomplished by several enzymes, including two pancreatic enzymes: trypsin and chymotrypsin. Peptides are broken into smaller peptides, and peptidases reduce the enzymes to amino acids.Nucleases digest nucleic acids into nucleotides in the small intestine also.The products of digestion enter cells of the villi, move across the cells, and enter blood vessels called capillaries. Diffusion accounts for the movement of many nutrients, but active transport is responsible for the movement of glucose and amino acids. The products of fat digestion pass as small droplets of fat into lacteals, which are branches of the lymphatic system.Substances that have not been digested or absorbed then pass into the large intestine.Large intestine -\xa0The large intestine\'s chief functions are to absorb water and to store, process, and eliminate the residue following digestion and absorption. The intestinal matter remaining after water has been reclaimed is known as feces.\xa0The feces are stored in the rectum and passed out through the **** to complete the digestion process.

Why was hydrogen given a separate position in periodic table |
| Answer» Hydrogen shows some similarity with both alkali metals and halogens, it differs from them on some grounds. Unlike alkali metals, hydrogen does not possess metallic characteristics. On the other hand, it possesses a high ionization enthalpy. Also, it is less reactive than halogens.Owing to these reasons, hydrogen cannot be placed with alkali metals (group I) or with halogens (group VII). In addition, it was also established that H+\xa0ions cannot exist freely as they are extremely small. H+\xa0ions are always associated with other atoms or molecules. Hence, hydrogen is best placed separately in the periodic table. | |

Why voltmeter is connected in parallel and ammeter in series? |
| Answer» Ammeter: In series connection, the same current flows through all the components. Ammeter aims at measuring the current flowing through the circuit and hence, it is connected in series: so that the same current that is there in the circuit flows through it and gets measured.Ammeter has a low resistance, because we do not want to change the current that is flowing through the circuit.Voltmeter:\xa0A voltmeter measures voltage change between two points in a circuit. So u have to place the meter probes at these two points, without removing the portion of circuit between the probes (or else you change the circuit). This then, by definition, places the voltmeter in parallel with the section of circuit between the probes.When you place the meter probes at the two points you want to measure, a tiny portion of the current in the circuit will now go thru the meter and give you a reading. We make the voltmeter a very high resistance instrument. So when the current splits into the meter the high resistance allows only a tiny amount of original current to split into the meter. | |

Why is it necessary to balance a chemical equation |
|
Answer» The chemical equation needs to balance because of law of conservation of mass. The chemical equation needs to be balanced so that it follows the law of conservation of mass. A balanced chemical equation occurs when the number of the different atoms of elements in the reactants side is equal to that of the products side. Balancing chemical equations is a process of trial and error. It is necessary to balance because to obey the law of conservation of mass ie. Mass of reactant is equal to mass of product |

Plz explain the process of human respiratory system |
| Answer» Respiratory system in human beings:The respiratory system in human beings consists of the nose, pharynx, larynx, trachea, bronchi and lungs.\tAir is taken in through the nostrils.\tNostrils further continue into the nasal cavity.\tThere is a bony plate called the palate, which separates the oral cavity from the nasal cavity.\tNasal cavity opens into the pharynx.\tThe pharynx is a muscular chamber acting as a common passage for the windpipe or trachea and the food pipe or oesophagus.\tIt is connected to the larynx through a slit-like opening called the glottis.\tThe larynx connects the pharynx to the trachea.\tThe trachea shows the presence of cartilaginous rings.\tThe cartilaginous rings provide flexibility thus, facilitating continuous air flow.\tThe inner wall of the trachea is lined by a mucous membrane consisting of ciliated columnar epithelium.\tThe trachea divides into two branches or tubes called bronchi, one of which enters the right lung and the other enters the left lung.\tThe bronchi have cartilaginous rings for distention.\tEach bronchus divides into fine secondary bronchi. These bronchi further divide into finer tertiary bronchi. In the lungs, each bronchus finally divides into finer and smaller branches called bronchioles.\tThe bronchioles further divide to form smaller terminal bronchioles.\tThe bronchioles divide repeatedly to form a cluster of tiny air chambers called air sacs or alveoli.\tAlveoli have thin and moist walls which enable gaseous diffusion with blood capillaries.\tThe lungs are a pair of spongy and elastic respiratory organs protected by a bony rib cage.\tThe base of the lungs rests on the diaphragm.\tEach lung is covered by two membranes. The inner membrane is called the inner or visceral pleura and the outer membrane is called the outer or parietal pleura.\tThe diaphragm is a curved, musculo-fibrous sheath which separates the thoracic cavity from the abdominal cavity.\tThe diaphragm plays a major role during respiration. | |

Explain digestion in man |
| Answer» A human digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. The food we take in is digested and utilized by our body and the unused parts of the food are defecated. Human digestive system is the sum of the gastrointestinal tract (GIT; also called alimentary canal) and accessory organs (tongue, liver, pancreas, etc). These two parts together help in digestion in humans.The alimentary canal is the long tube through which the food that we eat is passed. It begins at the mouth (buccal or oral cavity), passes through the pharynx, esophagus or food pipe, stomach, small intestines, large intestines, rectum and finally ends at the ****. The food particles get digested gradually as they travel through various compartments of the alimentary canal. Accessory organs are organs which participate in the digestion process but are not actually a part of GIT. They stimulate the digestion by releasing certain enzymes.Food begins its journey through the digestive system in the mouth, also known as the buccal cavity or the oral cavity. The mouth has many accessory organs such as the tongue, teeth, and salivary glands, which help in the digestion of food. Teeth grind the food into small pieces. Salivary glands secrete saliva which contains an enzyme called the salivary amylase. This enzyme breaks down starch content and moistens the food, before the tongue and other muscles push the food into the pharynx.\xa0Pharynx: The pharynx passes the chewed food from the mouth to the esophagus. The flap of tissue known as the epiglottis present in pharynx prevents food from entering into the wide pipeEsophagus or Food Pipe: The esophagus is a muscular tube connecting the pharynx to the stomach. It carries swallowed masses of chewed food along its length and pushes it down to the stomach.\xa0Stomach: The stomach is a thick-walled muscular bag that is located on the left side of the abdominal cavity. It is the largest part of the human digestive system. Stomach acts as a storage tank for food so that the body has time to digest large meals properly. It receives food from the food pipe at one end and opens into the small intestine at the other end. The inner walls of the stomach consist of the gastric glands which secrete mucous, hydrochloric acid and digestive enzymes. These continue the digestion of food that began in the mouth.Mucous protects the lining of the stomach while acid kills bacteria that enter the body along with the food. Hydrochloric acid also makes the medium in the stomach acidic, which helps the digestive enzymes like pepsin to act. The digestive enzymes break down proteins into simpler substances.Small Intestine: The small intestine is the longest part of the human digestive system. It is a highly coiled long, thin tube which is about 7.5 metres in length. The length of the small intestine depends on the diet of the organism. A major proportion of digestion takes place in the small intestines. All types of nutrients are digested here with the help of secretions which it receives from the liver and the pancreas. The walls of the small intestine also secrete juices for digesting food.The liver releases bile juice which alkalizes the acidic food received from the stomach and also emulsifies the fat content. The pancreatic juice digests the proteins and lipids. Finally, the intestinal secretions convert the carbohydrates into glucose, proteins to amino acids and fats into fatty acids and glycerol.Once the food is broken down into the simple particles, it is ready to be absorbed by the body. The villi, finger-like projections present on the walls of the small intestine, absorb the digested food by increasing the surface area. The absorbed food is then transported to different parts of the body through the blood vessels for cell activities.Large Intestine: The large intestine is a long, thick tube which is about 1.5 meters long. The large intestine absorbs water and small amounts of nutrients from the undigested food with the help of many symbiotic bacteria residing in it. The remaining waste passes into the rectum, where it remains as semi-solid feces. Feces exit the body through the **** via time-to-time excretion. This process is called Digestion. | |
