the elasticity of lung tissue causes ____
incrased radial traction
Which of the following would cause bronchodilation within the lungs?
Local release of histamine in an immune response
Increased CO2 levels within the bronchioles
Administration of a Beta-2 adrenergic receptor blocker
Inhibition of the Sympathetic Nervous System
increase Co2 levels within bronchioles
Which of the following would DECREASE the diffusion rate of a gas from point A to point B?
Increased surface area for diffusion
Increased concentration gradient of the gas from point A to point B
Decreased barrier thickness between point A and point B
Increased distance for diffusion of the gas between point A and point B
Increased distance for diffusion of the gas between point A and point B
Which of the following lung volumes would you expect to increase in obstructive lung disease?
residual volume
Which lung volumes would you expect to decrease in restrictive lung disease?
all of them
wat would produce thte highest FEV1/FVC raio
restrictive lung diseas
which of the following would you see a signafacnt reuction in lung volume flow rates
obstructive = signigicant reudction
resiticitve = some redution
he breakdown of alveolar walls seen in Emphysema will lead to:
decrased SaA fro gas exxhange
In late stage chronic bronchitis, lower ventilation leads to vasoconstriction within pulmonary circulation. This can eventually cause congestive heart failure because:
right ventricle eventually weakens and ncant contract forcefully enough to overome the high pressure in pumonary circulation
Which of the following metabolic fates is NOT a consequence of insulin deficit?
Increased Gluconeogenesis (liver)
Increased Lipolysis
Increased Ketogenesis
Increased Glycogenesis
incrased glycogensis - would decrase aility for gluose to convert clycogen incell - cant get cglucose into cell
Which of the following is an accurate distinction between Type 1 and Type 2 Diabetes? SAuttominutiy>
Type 1 is automimmubne
Which of the following would you expect in type 2 diabetes
Elevated fasting blood glucose level
Prolonged return of blood glucose to fasting levels
, Not Selected
Elevated level of Hemoglobin A
all
Which of the following would arise first in the pathogenesis of type 2 diabetes?
Hyperinsulinemia (high blood insulin levels)
Insulin Resistance
Beta cell destruction
Increased beta cell mass
insuline rsistance
Increased adiposity can lead to insulin resistance due to:
increased cirucaltion of fatty acids - atty acids interfere with insulin signaling in muscle and liver cells, leading to insulin resistance
Which of the following is NOT considered a criteria for diagnosing metabolic syndrome?
Correct answer:
Atherosclerosis
Visceral adiposity (obesity)
Insulin Resistance
Hypertension
atherosclerosis
A cancer found to originate within epithelial cells of the stomach would be considered a:
carcinoma
A stage IV carcinoma would suggest that
cancer has spread to dsitant cells in body and has poor progniosis
Benign tumors can often be differentiated from malignant tumors because benign tumors
are encapsulated and slow growing
ith respect to the spread of cancer, which of the following reflect the spread along membranes or through fluid within a body cavity?
seedk g
Claudication is a symptom of peripheral artery disease. What is ‘claudication’?
pain due to ischemia in the limbs
Why can left ventricular hypertrophy lead to symptoms of angina?
because the metbaolic demande of hear increases and suply us not fully mathcin this icnreased demand
A deep vein thrombosis that dislodged would put someone at highest risk for which of the following?
pulmonary embolism
A blood pressure of 135/80 would be considered
staeg 1 hypertension
Which of the following is thought to explain the pathophysiology of Primary Hypertension?
excess sodium retention in blood lead causing an increase in blood volume
