CELL TISSUE ORGAN SYSTEM ORGANISM

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
