Document Summary
Connective tissue-blood-between living cells- cartilage: dermins- fact cells, skin, tendons, ligimants, cartilage, bone, blood and lymph have connective tissue. Organs composed of 2 or more tissue types: skin has all 4 tissue types, epidermis- epithelial, dermis- connective, bcells- antibodies. For the final tie together the organ systems. Circulation ( artery and vein system) this one ties all of the organ. Systems together: fluid that circulates (blood, channel (vessels) that the fluid circulates through, pump (heart) to keep fluid moving. Make atp or will die when waste build up) Some waste co2, urea( ammonia: distribute hormones, regulate body temperature. Dilate vessels bring down body temp when hot. Cold try to keep heat in body: prevent blood loss, defend against disease. Bcells, tcells, macrophages: vertebrate heart, 2chamber- fish, 3chamner- amphibians, reptiles, 4chamber heart- birds and mammals. Birds are reptile with 4 chamber heart evolving from own lineage divergent evolution from humans. Atrium first then ventricles (blue blood deoxygenated blood)
