What is caused by blood flow back through a stenotic valve?
palpitation
Where does blood pumped by the left ventricle pass through?
Blood enters the left ventricle from the left atrium by passing through the mitral valve. The mitral valve functions to prevent blood from flowing back into the left atrium when the left ventricle contracts.
Where does blood flow to after it leaves the atrium and passes through the biscuspid valve?
Oxygenated blood from the lungs flow back into the heart via the left pulmonary veins into the left atrium, through the bicuspid (mitral) valve, into the left ventricle.
What is the function of the tendons of the valve?
To prevent the valve from opening in the other direction when the ventricles contract - this way, the blood doesn't go back through where it came from.
What prevents blood from flowing back into the heart?
The valve
The sound created when blood leaks back through an incompletely closed valve is called what?
Regurgitation
What is the function of the tricuspic valve?
The tricuspid valve is an atrioventricular valve on the right side of the heart. When the right ventricle contracts, it forces the tricuspid valve closed preventing blood from flowing back into the atrium. Instead, all the blood will be forced out through to pulmonary arteries to the lungs.
What is a leaking aortic valve?
A leaking aortic valve means that when your hears pumps blood through the valve, that the valve does not close of properly when it should. This causes your heart to have to work harder because some of the blood it pumps leaks back into the heart and needs to be pumped out again.
The aortic valve separates the aorta from this structure?
The aortic valve is a tricuspid valve that separates the aorta from the left ventricle. The heart pumps blood from the left ventricle, through the aorta, to the body, and the aortic valve prevents the back flow of blood into the left ventricle as the ventricle relaxes and refills with blood from the left atrium.
What is pulmonary valve?
The pulmonary valve is a semilunar valve that prevents the back flow of blood back from the lungs to the right ventricle.
When are the pulmonary valves closed?
When the blood flows from the right ventricle, it passes through pulmonic valve before it reaches pulmonary artery. Pulomic valve closes as blood passes here to prevent back flow.
Describe the path of blood flow through the heart?
Venous blood enters the heart through the superior and inferior venae cavae into the right atrium. From the atrium they exit the tricuspid valve into the right ventricular. The blood exits the right ventricle through the pulmonary valve into the pulmonary veins towards the lungs. Oxygenated blood returns through the pulmonary veins into the left atrium, Then, it enters the left ventricle through the mitral valve. From the left ventricle it passes through the aortic valve, and into the aorta.
