hydrostatic pressure exerted by the blood on the vessels as the heart pumps

A

Blood pressure

20
Q

expansion and recoil of an artery as the heart pumps blood

A

Pulse

21
Q

form of energy, product of metabolism

A

Heat

22
Q

air pressure used for breathing and hydrostatic pressure helps blood movement

A

Atmospheric pressure

23
Q

ability to maintain constant internal enviroment

A

Homeostasis

24
Q

built in control mechanisms

A

How does body maintain homeostasis?

25
Q

body communicates through receptors (stimuli) then directs it towards the control center (set point, goal) which in turn controls the effector (muscle/gland)

A

Control Mechanisms

26
Q

depresses stimulus, self-limiting reactions, prevents change from going too far

A

Negative feedback

27
Q

enhances stimulus, promotes itself, can get out of control and produce unstable conditions

A

Positive feedback

28
Q

Study of the structure of body parts and their relationships to one another

A

What is anatomy?

29
Q

Study of the function of living organisms

A

What is physiology?

30
Q

Subatomic Particles, Atoms, Molecules, Macromolecules, Organelles, Cells, Tissues, Organs, Organ Systems, Organism

A

Levels of Organization (from simple to complex)
