Body Systems and Frog Pre-Lab

What's My Function? Circulatory Digestive Endocrine Excretory Immune Muscular Nervous Reproductive Respiratory Skeletal Skin(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 Gas Exchange of oxygen and carbon dioxide Supports the body, protects it and works with muscles to allow movement Protects the body, keeps water inside the body & regulates body temperature
