Deoxygenated venous blood → Sup. Vena Cava →
Right Atrium →Tricuspid (AV) →Empties into R.
Ventricle (& it contracts) → Blood ejected through
How does blood flow
Pulmonary Valve → Pulmonary Artery → Lungs to be
through the heart?
Oxygenated → Pulmonary Veins → L. Atrium → Mitral
(AV) → L. Ventricle (pumps with each contraction) →
Aortic Valve → Aorta → Body
What is systole? Contraction of the heart which pumps blood
Diastole Relaxation of the heart
, What produces S1 and S2 closing of the heart valves
sound?
What produces S1? The mitral and tricuspid valves which close in systole
The closing of the aortic and pulmonic valves in
What produces S2 sound?
diastole
the volume of blood pumped out by each ventricle
What is cardiac output?
per minute
amount of blood pumped out by each ventricle with
What is stroke volume?
contraction
What determines cardiac stroke volume and heart rate
output?
the degree of stretch on the heart before it contracts,
related to ventricular filling, end diastolic pressure,
What is preload?
amount of blood entering the ventricle during
diastole
resistance left ventricle must overcome to circulate
What is afterload?
blood
Normal ability of muscle to contract at a given force
What is contractility? for a given stretch. It is independent of
preload/afterload
Will sustained tachycardia Decreased
result in increased or
decreased stroke volume?
What conditions can result Ischemia, acidosis, cardiomyopathy
in decreased contractility?
What can cause increase HTN, pulmonary disease, damage to the aortic valve
afterload?
What has the most HTN
immediate effect on
afterload?
