Body Systems and Frog Pre-Lab Slide 2 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 Slide 3 Levels of Organization chemicals atoms molecules macromolecules organelles cells tissues organs organ systems organism Slide 4 Amphibians Kingdom:Animalia Phylum:Chordata Order:Anura Family:Ranidae Genus:Rana Species:pipiens Frog Sound Leopard Frog Slide 5 Amphibians Lobe-finned fish gave rise to early amphibian Coelacanth ~ 6.5 feet Early Amphibian ~ 15 feet Slide 6 Amphibian Characteristics 1.
