Emergent properties= properties that cannot be predicted to exist based only o knowledge of the system"s individual components o. Atoms-> molecules-> cells-> tissues-> organs-> organ systems-> organisms-> populations of one species-> ecosystem of different species-> biosphere. 10 physiological organ systems: o o o o o o o o o o. Circulatory- transport of materials between all cells of the body (heart, blood vessels, blood) Digestive- conversion of food into particles that can be transported into the body; elimination of some wastes (stomach, intestine, liver, pancreas) Endocrine- coordination of body function through synthesis and release of regulatory molecules (thyroid gland, adrenal gland) Immune- defense against foreign invaders (thymus gland, spleen, lymph nodes) Musculoskeletal- support and movement (skeletal muscles and bone) Nervous- coordination of body function through electrical signals and release of regulatory molecules (brain and spinal cord) Reproductive (ovaries and uterus, testes) perpetuation of the species.
