1- (a) A heart is a living pump that pumps oxygen and nutrient-rich blood throughout your body to sustain life. 2- (d) Food and oxygen are the materials that are needed by every living cell. The cells of all living organisms can release the energy in their food by a process called respiration. 3- (b) A waste product like urea, uric acid etc., produced by the body during metabolic activities are toxic and can poison the organism. 4- (f) Red blood cells contain pigment haemoglobin which is essential for transferring oxygen in your blood from the lungs to the tissues. 5- (c) Circulation is the movement of materials throughout the body. The circulatory system is made up of blood vessels that carry blood away from and towards the heart. 6- (e) Arteries and vein transport the oxygenated blood from the heart to the rest of the body and deoxygenated blood from the body to the heart. Oxygenated blood is rich in oxygen and deoxygenated blood is rich in carbon dioxide. So these are known as the pipes for the transport in man.

Sweating is the process by which liquid is released from the body's sweat glands. The sweat contains salt and water. The process of sweating is also called perspiration. Sweat is a type of waste commonly found under the arms, on the feet, and on the palms of our hands. In summer, mostly on hot days, we used to sweat to keep our body cool.
