study of ONE function in MANY different groups of organisms

11

Closed circulatory system means

blood pumps through veins, arteries, etc. continuously and on the inside (unless cut open)

12

Homeostasis

the body's mechanisms used to keep the body stable (wave shape)

13

Negative feedback mechanisms

takes what's wrong and tries to reverse it

14

Neg. fdbk mech. examples (4)

1. Sweating- to cool body down 2. Vasodilation- blood vessels expand 3. Shivering- to warm body up 4. Vasoconstriction- blood vessels get smaller

15

Positive feedback mechanisms

speeds up a bad thing to get it over with quicker
