Cardiovascular Flashcards
What organ helps the heart maintain blood pressure and how
Kidney, increases blood volume through renin-angiotensin system
Which heart chamber has the thickest muscle because it pumps blood through the body
Left ventricle
What occurs during ventricular systole
Ventricles contract and pulmonary and aortic valves open
Which electrolytes enter heart cells during depolarization
Sodium and calcium
What is the correct way for the hearts electrical conduction system
SA node, AV node, Bundle of his, and purkinji fibers
Which chamber receives blood from the pulmonary vein
Left Atria
Contraction of the atria coincides with which waveform on the ECG
P wave
Ventricular depolarization coincides with which waveform on the ECG
QRS
Which factor, that helps determine cardiac output, is the resistance the left ventricle experiences when it tried to eject blood into the aorta ?
After load
