HCR240 Pathophysiology midterm || A+ Certified.
simple diffusion correct answers method of transport for o2 and co2 across the alveolar
membrane
filtration correct answers The movement of water and solutes resulting from greater pressure on
one side of the membrane than on the other side
Carrier-mediated facilitated diffusion correct answers Transport used to carry glucose from one
side of cell membrane to the other requiring transport proteins to change shape
Na/K pump correct answers Specialized type of active transport that moves sodium and
potassium across the cell membrane against the gradient
phagocytosis correct answers Process in which a macrophage engulfs a pathogen
osmosis correct answers Movement of water through a selectively permeable membrane from an
area where there is more water to an area where there is less water
active transport correct answers Mechanism used by thyroid gland in iodine uptake; requires the
use of ATP
pinocytosis correct answers Cell drinking
receptor-mediated endocytosis correct answers method of cholesterol transport into cells
endocytosis correct answers Process by which the cell takes in particles by engulfing and fusing
them with its plasma membrane to form an intracellular vesicle
,exocytosis correct answers Process by which cells export molecules using membrane-bound
vesicles, which fuse with the cell membrane and expel their contents outside of the cell
ischemia correct answers When the clot interrupted blood flow from his major coronary artery to
his heart, this caused the initial injury to Mr. Epperson's myocytes.
hypoxia correct answers Because of decreased blood flow to his heart, some of Mr. Epperson's
myocytes suffered this type of injury due to decreased oxygen delivery.
necrosis correct answers When the clot blocked blood flow to Mr. Epperson's heart, lack of
oxygen caused a decrease in ATP resulting in what?
oxygen correct answers The IV medications allowed this to be restored to the myocytes, limiting
damage to Mr. Epperson's heart muscle.
reperfusion injury correct answers The type of injury Mr. Epperson's myocytes are vulnerable to
after the clot is dissolved and normal blood flow is restored to his heart.
respiratory acidosis correct answers A drop in blood pH due to hypoventilation (too little
breathing) and a resulting accumulation of Co2.
respiratory alkalosis correct answers high pH, low CO2, normal HCO3
metabolic acidosis correct answers low pH, normal PaCO2, low HCO3
metabolic alkalosis correct answers high pH, normal co2, high HCO3
T/F: edema is the accumulation of fluid in the interstitial space correct answers True
, Stem cells are: correct answers often called self-renewal cells
which of these is the term for cellular ingestion of large particles, also known as "cell eating"?
correct answers phagocytosis
T/F: active transport is the mechanism used by the thyroid gland in iodine uptake correct answers
True
which of these is the basic unit of inheritance? correct answers the gene
T/F: aldosterone is the hormone that regulates blood sodium and potassium levels correct
answers True
sodium accounts for what percentage of extracellular fluid cations? correct answers 90%
apoptosis correct answers programmed cell death that maintains the health of the body by
eliminating old, unnecessary cells
which of the following describes the study of changes in gene expression that do not change the
DNA sequence? correct answers epigenetics
which would support the diagnosis of respiratory acidosis? correct answers hyperventilation???
which of the following patients is the most at risk for developing hypernatremia? a patient with:
correct answers dehydration???
methamphetamine exposure can cause different symptoms based on prior disease or functioning
in the individual. A symptom in a healthy individual would be: correct answers aggressive
behavior
