WCU -Phys 261 Final EXAM WITH 100%
CORRECT ANSWERS
Physiology - Normal functioning of a living organism and its components (parts; including
chemical and physical)
Homeostasis - Maintaining a stable internal environment
Placebo - A drug treatment that is expected to have no pharmaceutical effect on
humans/animals
Cations - positively charged ions
Isotopes - two or more forms of the same element that contain equal numbers of
protons but different numbers of neutrons in their nuclei. differ in relative atomic mass but not
in chemical properties.
Active cellular transport - is the movement of molecules across a membrane from a
region of their lower concentration to a region of their higher concentration—against the
concentration gradient. Requires cellular energy.
Absolute Refractory period - during which a second action potential cannot be triggered
no matter how large the stimulus
Isotonic muscle contraction - Creates force and moves the load EX) lifting weights
isometric muscle contraction - creates force without moving a load Ex) wall planks
