Biology

This is the study of the chemical components of food known as nutrients and their significance to organisms. All organisms need food materials to obtain nutrients for survival, but the procedure of obtaining them varies among organisms

Biology

Transport involves the movement of materials from one part of the organism to another. In animals, it is basically the circulatory system. The system consists of the heart and blood vessels. Blood flow through the system is maintained by the heart, skeletal muscles, valves, and inspiratory movements. The heart is myogenic. Blood transports dissolved substances such as respiratory gases, water, food materials, etc

Biology

The movement of materials within the body tissues or between tissues in multi cellular organisms like high plants and animals occurs in transport systems. In unicellular or low plants and animals, such movement is by the transport mechanisms of molecules within a transport medium by diffusion, osmosis, active transport and mass flow, among others

Biology

When nutrients are absorbed in cells, the metabolic process converts the nutrient chemical compounds into energy following a biochemical system set in living cells. This energy is stored as potential energy in body tissues and released when required by the body’s biological processes.
