• 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 means of chemicals (hormones)
• Removes body wastes
• Fights diseases
• Enables the body to move (voluntary & involuntary motion)
• Detects and interprets information from the environment outside the body and within the body
• Produces sex cells & controls male & female characteristics, reproduction
• Brings in the oxygen that is carried by 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
