After it is filled, the right ventricle pumps the blood through the pulmonary arteries to the lungs for re-oxygenation.Īfter blood passes through the pulmonary arteries, it will have visited the lungs and picked up oxygen it is not oxygenated. This deoxygenated blood then passes to the right ventricle through the right atrioventricular valve (tricuspid valve), a flap of connective tissue that opens in only one direction to prevent the backflow of blood. The right atrium also receives blood from the inferior vena cava, which drains blood from the veins of the lower organs and legs. The journey of the blood starts in the right atrium, which receives deoxygenated blood from the superior vena cava, which drains blood from the veins of the upper organs and arms. The atria are the chambers that receive blood while the ventricles are the chambers that pump blood. There are one atrium and one ventricle on the right side and one atrium and one ventricle on the left side. It is divided into four chambers: two atria and two ventricles. In humans, the heart is about the size of a clenched fist. It has four chambers: two atria and two ventricles. Now test your knowledge on the blood flow of the heart by taking this quiz.The heart is a complex muscular organ that pumps blood through the three divisions of the circulatory system: the coronary (vessels that serve the heart), pulmonary (heart and lungs), and systemic (systems of the body). Try to remember that A is before V in the alphabet so atriums (which starts with the letter A) is above the ventricles (which starts with the letter V). By remembering this phrase, you will remember that the tricuspid (try) is before the bicuspid (buy) valve.Īlso, don’t left the atriums and ventricles mess you up either. Remember this saying, “First always try, before you buy”. Many people get confused on if the blood enters the tricuspid or bicuspid valve first. Lastly up through the AORTA, where it pumped throughout the body Then blood is squeezed into the LEFT VENTRICLEġ2. Down through the BICUSPID VALVE (also called mitral valve)ġ0.

Blood enters from the lungs through the PULMONARY VEINĨ. Goal: to get the richly, oxygenated blood that LEFT the lungs to the body to feed the brain, tissue, muscles, organs etc.)ħ. Remember in medical terminology pulmon means lungs. This will help you keep from getting confused with the left side of the heart.

Study Tip: Since the goal of the right side is to get blood to the lungs always remember that the pulmonic valve and pulmonary artery will be on the right side since it is associated with the lungs. Blood is then shot up through the PULMONARY ARTERY and then enters into the lungs for some oxygen Then it is squeezed into the PULMONIC VALVEĦ. Blood then enters into the RIGHT VENTRICLEĥ. Then it is squeezed through the TRICUSPID VALVEĤ. The un-oxygenated blood (this is blood that has been “used up” by your body and needs to be resupplied with oxygen) enters the heart through the SUPERIOR AND INFERIOR VENA CAVA.ģ. Goal: to get the blood RIGHTto the lungs so it can become oxygenated.ġ. Study Tip: When you are having to memorize this for a test, think of the blood flow like this: There are 12 steps, 6 for the right and 6 for the left. The right side is in blue and the left side is in red. For better illustration, look at the picture below and note how the right and left side are separated. Always remember that it must flow through 6 areas on the right side and then 6 areas on the left side (this equals 12 steps). Learn Heart Blood Flow in LESS than 4 Minutes!!īlood flows through the heart in 12 easy steps. I found that learning the blood flow of the heart is best done by actually visualizing how the heart is set-up and how it flows through the muscle to the body.Īfter reviewing these notes, don’t forget to take the heart blood flow quiz.
