GCU BIO 201 HUMAN ANATOMY AND
PHYSIOLOGY I EXAM SCRIPT
COMPREHENSIVE TEST BANK REVIEW SHEET
SOLVED QUESTIONS AND ANSWERS
◉ Pinocytosis. Answer: Cell drinking
◉ Phagocytosis. Answer: Cell eating
◉ Exocytosis. Answer: release of substances outside a cell by the
fusion of a vesicle with the membrane.
◉ Endocytosis. Answer: process by which a cell takes material into
the cell by infolding of the cell membrane
◉ osmosis. Answer: Low to High, Diffusion of water through a
selectively permeable membrane
◉ Diffusion. Answer: Movement of molecules from an area of higher
concentration to an area of lower concentration.
◉ tonicity. Answer: the ability of a surrounding solution to cause a
cell to gain or lose water
, ◉ isotonic solution. Answer: when the concentration of two solutions
is the same (moving in and out equally)
◉ hypertonic solution. Answer: A solution in which the concentration
of solutes is greater outside then inside the cell that resides in the
solution
◉ hypotonic solution. Answer: Solute concentration is less than the
inside the cell; cell gains water
◉ oncotic pressure. Answer: pulls fluid into the capillaries and/or
prevents fluid from leaving.
◉ hydrostatic pressure. Answer: increases filtration by pushing fluid
and solute OUT of the capillaries
◉ crenation. Answer: This happens when a cell shrinks and shrivels;
can result in cell death if severe.
◉ hemolysis. Answer: destruction/split of red blood cells
◉ active transport. Answer: the movement of ions or molecules across
a cell membrane into a region of higher concentration, assisted by
enzymes and requiring energy.
