Through Can you stand the heat-Again? Notes OUT Study for the test.(Friday)

Can you stand the heat-again? Open your book to page 166. Create a concept map of the following terms Diffusion, Water, Gas Exchange, osmosis, Compartment, concentration gradient, waste removal, cell membrane, environment, internal conditions, homeostasis

Read the conclusion (purple box) Diuretic- any substance or agent that promotes the increased formation and excretion of urine. (caffeine)

Analysis 1. What percentage of body mass did Josh lose in the form of fluids? – %body mass lost=(final mass-original mass)/ origninal mass) X In what ways was Josh’s body attempting to maintain an internal balance in spite of the changing nature of his external environment?

3. How did Josh become dehydrated even though he drank 1.9 liters of liquid? 4. How could Josh’s water loss have caused him to become dizzy? 5. Do you think that Josh would have been better off to replenish his fluids by drinking iced coffee or tea rather than the energy drink? Explain.

Careful coordination page 231 Nervous system-regulates automatic response(shivering) -nerves, brain, spinal cord Neuron-send nerve impulses Glial cells-protect neurons Brain-cerebrum, cerebellum, hypothalamus

Hypothalamus-water balance, body temp, feeding, sleep, endocrine system Endocrine system-produce and release chemical messages (hormones) male: testosterone female: estrogen

Receptor-proteins that fit the shape of a specific hormone molecule Dehydration-hypothalamus (due to high sodium); pituitary gland releases vasopressin, travels to kidneys; kidneys respond- membrane is more permeable to reabsorb water
