Organisms require many different organ systems to carry out activities required for life.

Examples of Life Processes:

Digestion: breakdown of food so that they can enter cell.

Circulation: movement of materials in an organism or cells.

Movement/Locomotion: change in position.

Excretion: removal of waste products, ex. CO2, H2O, urine and sweat.

Respiration: conversion of energy in food to ATP which cells can use.

Reproduction: making of more organisms.

Immunity: ability to resist disease.

Coordination: control over various activities (nervous system, and endocrine glands).

Synthesis: production of more complex substances by combining other substances together.
