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