Pharmacology Exam 3 Cardiovascular
System Questions And Answers
what part of the heart collects blood, the chamber that fills
atria
what part of the heart is known as the "pumping part of the heart"
ventricle
what is another name for the mitral valve
bicuspid
put the valves of the heart in order
tricuspid, pulmonic, mitral, aortic
put the hearts electrical conduction system in order
SA node, AV node, bundle of his, bundle branches, Purkinje fibers
what is cardiac output
how much blood the heart pumps in one minute
what is right ventricle hypertrophy
when the muscle wall of the right ventricle becomes thickened
what is right ventricle hypertrophy caused by and why
issues with the pulmonary system because when something in the lungs increases
resistance to blood flow, the right ventricle has to push harder
what is the most common cause of left ventricle hypertrophy
high blood pressure
why is left ventricle hypertrophy caused by hypertension
, the arteries have higher pressure and resistance and the left ventricle has to generate
more force to push blood out into the aorta
what is a fast heart rhythm that starts in the ventricles
ventricular tachycardia (v tach)
what is happening during v tach and what can it cause
The ventricles are firing rapidly on their own and blood does not have enough time to fill
leading to decreased cardiac output and low blood pressure
what is chaotic, disorganized electrical activity in the ventricles
ventricular fibrillation
what is happening during v fib
ventricles are quivering instead of pumping
what can a fib cause
clots
what is irregular, disorganized rhythm in the atria
atrial fibrillation
what disorder is increased systemic vascular resistance
hypertension
what do vessels do to compensate for hypetension
dilate
During hypertension do your arteries narrow or dilate
Narrow
chronic blood pressure elevation can lead to damage of what
blood vessels
a diet high in what can cause hypertension
