30
Q

Homeostasis

A

1) Body’s ability to maintain relatively stable conditions even though outside environment changes continuously.
2) Dynamic state of equilibrium.
3) Body is in homeostasis when it’s needs are met and it is functioning smoothly.

31
Q

Negative feedback

A
  • common mechanism of regulation
  • causes variable to change in opposite direction of initial change
    Ex. Thermostat
32
Q

Positive feedback

A
  • less common mechanism of regulation
  • causes variable to be enhanced in direction of initial change
    Ex. Contractions, breastfeeding
33
Q

Gross anatomy

A

Examining large structures

34
Q
