Transportation in Animals

Blood is the fluid that flows in the blood vessels and transports the digested food from the small intestine to various parts of the body. The heart is the main organ that pumps blood throughout the body. The process of removal of waste out of the cells is called excretion.

Answer 2

Answer:

Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.
