Mechanisms fo heart and lungs |
| Answer» Heart: Heart is a muscular organ; which is composed of cardiac muscles. It is so small that it can fit inside and adult’s fist. The heart is a pumping organ which pumps the blood. The human heart is composed of four chambers, viz. right auricle, right ventricle, left auricle and left ventricle.Lungs: The breathing mechanism of lungs is controlled by the diaphragm and the intercostalis muscles. The human respiratory system is composed of a pair of lungs. Diaphragm is a membrane which separates the thoracic chamber from the abdominal cavity. When diaphragm moves down, the lungs expand and air is inhaled. When diaphragm moves up, the lungs contract and air is exhaled. | |

It happens when the sum of the dragged force (Fd) and buoyancy is equal to the downward force of gravity (FG) acting on the body. The object holds zero acceleration since the net force acting is zero. | |

Explain the process of excretion in plants? |
| Answer» Elimination of toxic and waste products from the body is called excretion. Organisms like animals have an advanced and specialized system for excretion. But plants lack a well-developed excretory system like that in animals. They do not have special organs for excretion.The major waste substances produced by plants are oxygen, carbon dioxide and water. They can get rid of excess water by transpiration. Many of the toxic waste products are stored within dead permanent tissue which are removed periodically. Waste products are stored in leaves which may fall off. Some waste products such as latex, gum, resins are stored in old Xylem.Alkaloids are a group of toxic waste products. But some of these are useful to us. Quinine and morphine are medicines derived from alkaloids stored in Cinchona bark and opium poppy flowers respectively. Caffeine found in coffee seeds and nicotine in tobacco leaves is also alkaloids. | |
