How does medulla help the conduction system of heart?
Give this one a try later!
medulla controls ANS; chemoreceptors in blood detect changes,
baroreceptors in carotid arteries detect changes l/t hormones that
stimulate PNS/SNS w/epi/norepi release to control heart rate
,Define total lung capacity (TLC)
Give this one a try later!
volume of air in the lungs after a maximum inhalation
what are oncogene?
Give this one a try later!
oncogene is the result of mutation on photo-oncogenes' act like
accelerators, occurs mostly on somatic cells
what is the major treatment approach for gangrene?
Give this one a try later!
removing affective tissue to prevent infection; treating problem that led to
gangrene
What does low hemoglobin represent in cancer?
Give this one a try later!
, this represents low red blood cells, either due to bleeding, or because
cancer cell is diverting blood as it needs blood to grow .
what is ventilation-perfusion ratio? (VQ )
Give this one a try later!
measurement of the efficacy and adequacy of adequate ventilation and
sufficient perfusion
What do macrophages do in lung?
Give this one a try later!
phagocytize foreign substances; keep lungs clean
what is the advantage and disadvantage of radiation for colon CA?
Give this one a try later!
advantage = cancels cell mutation and interrupts tumor blood supply
Disadvantage = can damage normal cells including blood cells
Why does PO2 drops in COPD?
Give this one a try later!
, PO2 drops because there is decrease oxygenation occurring due to
damaged alveoli
how do cellular responses damage cells?
Give this one a try later!
with decrease ATP the Na/K pump fails and tissue swells damaging the cell.
What causes cell death in MI?
Give this one a try later!
unstable plaque breaks off, triggering platelet aggregation, coagulation
cascade and thrombus formation. continued no blood flow in 10 seconds
ischemia, 20 minutes cell die
Describe FAP - familial adenomatous polyposis
Give this one a try later!
Gene defect on chromosome 1 or 5; involves tumor suppressor genes,
hereditary condition
what are the three stages of shock progression?
