deep wound
more internal/deeper into tissue
pericardial membrane
covers the heart
pleural membrane
in and around the lungs
visceral membrane

homeostasis
the tendency of the body to maintain a stable environment
example of a positive feedback loop
contractions during childbirth
example of a negative feedback loop
sweating during exercise to cool the body down
anatomist
studies the position of body parts
physiologist
studies the function of body parts
what environmental factors do living organisms need?
water, wastes, carbon dioxide

stimulus->receptors->control center->effectors->stimulus

part below another part
anterior
towards the front
posterior
towards the back
medial
imaginary line down middle of body that divides it into equal right and left halves
lateral
to the side with respect to the medial line
proximal
