Document Summary
Chapter 31: homeostasis and the organization of the animal body: normal body temperature range: 97-99 f. Above 104 f, people get confused and may faint, brain cells die. (108 when people die) The body actively adjusts to ongoing internal and external changes to maintain constant conditions dynamic condition. Temperature: water and salt concentrations, glucose concentrations, ph(acid[low ph]-base[high ph] balance, oxygen and carbon dioxide concentrations, why are cells so picky, animal cells produce and use lots of atp. To produce atp, continuous supplies of high-energy molecules (primarily glucose) and. So, energy production is why glucose and oxygen levels are important: also, proteins" structures are maintained by hydrogen bonds, which can be disrupted if the. Many marine invertebrates, including snails, crabs, and worms, cannot regulate the overall concentration of their bodily fluids: animals vary in how and how well they generate heat and regulate body temperature. Scientists classify animals by their major source of body warmth.
