this is say earth register nurse re and calm and in this video I'm going to be going over blood flow of the heart and after you watch this YouTube video you can access the free quiz that will test you on heart blood flow so let's get started to easily understand the blood flow of the heart what you want to do is you wanted to buy the heart into two sides we have the right side of the heart and the left side of the heart and each of these sides has its own mission now the mission of the right side of the heart is to take the UH Knox ajaita blood that it received and get it to the lungs so the right side is going to take the blood right to the lungs to get oxygenated now the left side of the heart is going to it's responsible for oxygenated blood so it's just received oxygenated blood that has left the lungs to go throughout the body and what's really awesome to make it even easier to memorize is that each side the right on the left side has six structures where that blood has to flow so let's go through the blood flow of the heart okay everything starts on the right side of the heart and blood is being drained to the heart from the superior vena cava in the inferior vena cava and it's exhausted and it needs to get replenished with oxygen so it drains in down through the right atrium the atrium are always on top of the ventricles so remember that then it flows down through a valve and there are valves that separate your atrium from your ventricles over here on the right side we have the tricuspid valve and on the left side we have the bicuspid valve the mitral valve now how can you keep the two separated I like to remember the same try before you buy so the tricuspid valve bicuspid valve so the blood goes down through here then it goes down through the right ventricle the right ventricle squeezes it up through the pulmonary artery but the blood has to go through another Wow and it's called the pulmonic valve so it goes from right ventricle pulmonic valve to the pulmonary artery which the right side again takes it right to the lungs so that an oxygenated blood goes through the lungs and on your alveoli sacs or capillaries and you have this gas exchange going on so oxygen that you're breathing in is crossing over its hatching to those red blood cells and the carbon dioxide that's built up in your blood from this exhausted blood that's just been used from your body it's gonna cross over and you're gonna exhale it so the blood is nice and oxygenated and it has left the lungs to go into the left side of the heart through the pulmonary vein then it's gonna go down through the left atrium goes through another valve again what was that back valve the bicuspid valve the mitral valve so right here then it goes down through the left ventricle and then it's going to be shot up through the aorta but in order to get up through the aorta has to go through another valve which is the aortic valve so it crosses through the aortic valve up through the aorta and then it's gonna replenish your organs and your tissues okay so that wraps up the blood flow of the heart thank you so much for watching don't forget to take the free quiz and to subscribe to our channel for more videos
