Body Systems and Frog Pre-Lab
 Circulatory

Carries needed material to and waste away from the body
 Digestive

Takes in food, breaks it down, & absorbs nutrients
 Endocrine

Controls many regulatory processes by mean of chemicals
 Excretory

Removes waste
 Immune

Fights disease
 Muscular

Enables the body to move (voluntary & involuntary motion)

Detects and interprets information from the environment outside
the body and from within the body
 Reproductive

Produces sex cells & controls male & female characteristics
 Respiratory

Gas Exchange of oxygen and carbon dioxide
 Skeletal

Supports the body, protects it and works with muscles to allow
movement
 Skin(Integumentary)

Protects the body, keeps water inside the body & regulates body
temperature
 Nervous
