heart pathway <3 Flashcards
What is the pathway of blood from the body to the right atrium?
Blood flows from the body through the superior and inferior vena cava into the right atrium.
What is the next step after blood enters the right atrium?
Blood flows from the right atrium to the right ventricle through the tricuspid valve.
What condition can occur with tricuspid valve stenosis?
Tricuspid valve stenosis can cause narrowing, restricting blood flow from the right atrium to the right ventricle, leading to blood backup and swelling in the legs or abdomen.
What is a potential issue with a prolapsed tricuspid valve?
If the tricuspid valve prolapses, some blood may leak back into the right atrium, reducing efficiency.
What happens to blood after it leaves the right ventricle?
Blood flows from the right ventricle through the pulmonary valve into the pulmonary arteries and to the lungs for oxygenation.
What happens with pulmonary valve stenosis?
Pulmonary valve stenosis narrows the valve, restricting blood flow to the lungs, which can cause increased pressure and potential thickening and weakening of the right ventricle.
What could happen with a prolapsed pulmonary valve?
A prolapsed pulmonary valve can cause blood to leak back into the right ventricle instead of flowing to the lungs, reducing oxygenation.
How does oxygenated blood return to the heart from the lungs?
Oxygenated blood flows from the lungs to the left atrium through the pulmonary veins.
What happens after blood enters the left atrium?
Blood flows from the left atrium to the left ventricle through the mitral valve.
What condition can occur with mitral valve stenosis?
Mitral valve stenosis can narrow the valve, restricting blood flow from the left atrium to the left ventricle, causing blood to back up into the lungs, leading to shortness of breath and fatigue.
What happens with a prolapsed mitral valve?
A prolapsed mitral valve can cause blood to leak back into the left atrium, reducing the amount of oxygenated blood being pumped to the body.
What is the final pathway for blood after it leaves the left ventricle?
Blood flows from the left ventricle through the aortic valve into the aorta and is delivered to the body.
What happens with aortic valve stenosis?
Aortic valve stenosis narrows the valve, restricting blood flow from the left ventricle to the aorta, causing the left ventricle to work harder, potentially leading to heart failure.
What can happen with aortic valve prolapse or regurgitation?
Aortic valve prolapse or regurgitation can cause blood to leak back into the left ventricle after being pumped into the aorta, decreasing circulation and forcing the heart to pump harder.
