WCU PHYS 261 Lecture Final
questions well answered to pass
Physiology - correct answer ✔✔ The study of normal functions
Homeostasis - correct answer ✔✔ Relatively constant internal environment
Placebo - correct answer ✔✔ Treatment which has a positive mental effect, but no physical
effect
Cations - correct answer ✔✔ Positively charged ions (lose electrons)
Isotopes - correct answer ✔✔ Atoms of the same element with different numbers of neutrons
Active cellular transport - correct answer ✔✔ Against concentration gradient uses ATP
Refractory period - correct answer ✔✔ Inactivity after an action potential; another action
potential cannot occur
Isotonic muscle contraction - correct answer ✔✔ Moves loads
Isometric muscle contraction - correct answer ✔✔ Contraction without movement
Intercalated disc - correct answer ✔✔ Band connecting cardiac muscle cells
, MI - correct answer ✔✔ Myocardial infarction
Isovolumic ventricular systole - correct answer ✔✔ When ventricles contract with no
corresponding volume change
CO - correct answer ✔✔ Cardiac output every minute
Angiogenesis - correct answer ✔✔ Formation of new blood vessels
MAP - correct answer ✔✔ Mean arterial pressure
Erythropoietin - correct answer ✔✔ Produced and released by kidneys for RBC production
Pulmonary ventilation - correct answer ✔✔ Movement of air in and out of the lungs
Surfactant - correct answer ✔✔ Secreted by alveolar type II to reduce surface tension
Dalton's law - correct answer ✔✔ Total pressure = sum of all partial pressures
Boyle's law - correct answer ✔✔ Volume and pressure are inversely proportional (related)
Glomerulus - correct answer ✔✔ Knot of capillaries within the renal corpuscle (filtration)
Osmoreceptors - correct answer ✔✔ Detects osmolarity of the blood (water homeostasis) in
hypothalamus
Juxtaglomerular cells - correct answer ✔✔ Secrete renin when BP and sodium is low
