Responding to the world - 01 Why do we need body systems
Body systems are essential for multicellular organisms, as they enable cells to obtain nutrients and oxygen and dispose of wastes, which individual cells cannot do due to their distance from the external environment. The main body systems include the digestive, circulatory, respiratory, excretory, reproductive, nervous, endocrine, lymphatic, skeletal, and muscular systems. These systems work together to support the overall functioning and survival of the organism.

Their distance from the external environment means that not all body cells are able to exchange substances directly with it. Cells are therefore not able to obtain their own nutrients, oxygen & other substances needed for life processes; nor get rid of their wastes.
