Question

3.19 12c
kai is running in a marathon. as he starts running, his body temperature increases. his body responds by initiating a series of steps to return
his body to homeostasis. place the steps that kais body goes through in the correct order from the step that occurs first at the top, to the step
that occurs last at the bottom.
= body heat lost to surroundings
= body temperature begins to decrease
= blood vessels dilate; glands in the skin produce and then secrete sweat
unit 2.3 quiz- due 11/17

Explanation:

To determine the order, we analyze the homeostatic response to increased body temperature:

1. First, the initial response to rising temperature triggers Blood vessels dilate; glands in the skin produce and then secrete sweat (this is the first step as it's the body's immediate physiological response to start cooling).
2. Next, the sweat and vasodilation lead to Body heat lost to surroundings (the sweat evaporates and blood near the skin releases heat to the environment).
3. Finally, as heat is lost, Body temperature begins to decrease (this is the result of the previous cooling mechanisms, so it occurs last).

Answer:

1. Blood vessels dilate; glands in the skin produce and then secrete sweat
2. Body heat lost to surroundings
3. Body temperature begins to decrease
