Circulatory Digestive Endocrine Excretory Immune Muscular Nervous Reproductive Respiratory Skeletal Integumentary Carries needed material to and waste away from the body Takes in food, breaks it down, & absorbs nutrients Controls many regulatory processes by mean of chemicals Removes waste Fights disease Enables the body to move (voluntary & involuntary motion) Detects and interprets information from the environment outside the body and from within the body Produces sex cells & controls male & female characteristics, reproduction Brings in the oxygen that is carried on the RBC & carries the CO2 (waste gas) out of the body. Supports the body, protects it and works with muscles to allow movement Protects the body What's My Function?
