Document Summary
Moves materials around the body (ex: o2 from the lungs, wastes: urea from nitrogenous waste made from breakdown of amino acids) Immune system protects against pathogens from bacteria, viruses, ect. Immune system can protect against cancer (can get rid of cancerous cells) Immune system protects body from toxins (ex: snake or bee venom) Immune function through the white blood cells (leukocytes) in the cardiovascular system; antibodies (lymphatic system is also important in immunity) Regulation: hugely important in maintaining physiological homeostasis in body fluids (ex: transports oxygen important in regulating oxygen concentration, ph you"re in a cold environment, increase blood flow to deeper parts of the body buffer system) Regulates body temperature by vasoconstriction / vasodilation: if you go out and instead of skin; goes to surface if you need to cool down. Heart: muscular pump that provides pressure that moves the blood out of the heart and away from the heart through blood vessels (arteries)
