Anatomy - ANSWER: The study of body structure-
the heart, lungs, kidneys
Homeostasis - ANSWER: process by which organisms maintain a relatively stable
internal environment
negative feedback - ANSWER: A primary mechanism of homeostasis, whereby a
change in a physiological variable that is being monitored triggers a response that
counteracts the initial fluctuation.
positive feedback - ANSWER: Feedback that tends to magnify a process or increase
its output.-
childbirth
Levels of organization - ANSWER: atoms, molecules, cell, tissue, organ, organ system,
organism

sides and palms of the hands turned forward
Anterior (ventral) - ANSWER: toward the front
Posterior (dorsal) - ANSWER: toward the back
Superior - ANSWER: above, on top
Inferior - ANSWER: below/bottom
Medial - ANSWER: toward the midline
Lateral - ANSWER: away from the midline
Proximal - ANSWER: Closer to the point of attachment
Distal - ANSWER: away from the point of attachment
Physiology - ANSWER: The study of body function-
how muscles contract or how blood gets oxygenated and delivered to the body
sagittal plane - ANSWER: divides the body into unequal left and right halves
, mid-sagittal - ANSWER: Cuts body into a equal right and left portion

into simpler units by chemical reactions.
Ions - ANSWER: - positively and negatively charged atoms
- they form when electrons are either gained or lost
- they come from electrolytes (salts)
- cations (+) anions (-)
physical reaction - ANSWER: a change in matter that does not affect its chemical
composition, looks different-
tearing paper, chewing food
chemical reaction - ANSWER: changing matter into something completely different-
burning wood, rust
covalent bond - ANSWER: share electrons
oil and water- won't break in water - strong
ionic bond - ANSWER: strip electrons
