Pathophysiology test 3

Protein

Identify a component of the blood which cannot move across normal intact endothelium lining capillaries

atherosclerosis

Identify one long term consequence of uncontrolled primary HTN (don't answer death)

Afterload

The vasoconstriction which is present in HTN increases (preload or afterload) on the heart

SA node

Identify the normal pacemaker of the heart

Increased HR

Identify an effect of sympathetic stimulation on the heart

Increased contractility

Identify one compensation for heart failure

increased SV

How is that compensation beneficial to the individual

puts strain on the heart

How is that compensation harmful to the individual

glucose synthesis

identify a role for the liver in energy metabolism

Converts chylomicron remnants

Identify a role for the liver in lipid metabolism

Decrease glycogen synthesis

identify one response of the liver to insulin

Helps decrease glucose levels

Identify the effect that your response has on blood glucose concentration

Hyposensitivity to insulin

Identify the etiologic cause of diabetes type II

esterified cholesterol

identify one component of HDL

triglyceride

identify one component of LDL

Endogenous

High LDL represents excessive (endogenous or exogenous Lipid)

smoking

Identify one risk factor for atherosclerosis

GLUT 4

Production of angiotensin II

identify a stimulus for the secretion of renin as might occur in heart failure

Increased fluid retention

identify a consequence, or result, of the secretion of renin

Increased HR

Identify an effect of sympathetic stimulation on the heart

automaticity

identify the term, or characteristic of the heart, used to describe the depolarization which leads to action potentials in the heart

SA node

identify a tissue in the heart in which that depolarization occurs

ectopic pacemaker

identify a proposed physiologic mechanism for the generation of arrhythmias

Kidney

identify the organ, or tissue, which secretes renin
