Blood enters the heart through the superior and inferior vena cava. These two paths dump deoxygenated blood into the right atrium. Blood passes from the right atrium through the tricuspid valve into the right ventricle. The right ventricle contracts and forces the blood through the pulmonary semilunar valve into the pulmonary arteries. The blood moves into the lungs and gas exchange occurs, oxygenating the blood. The blood then moves through the pulmonary vein, emptying into the left atrium. The oxygenated blood then passes through the bicuspid valve into the left ventricle. The left ventricle contracts and forces the blood out through the aortic semilunar valve and into the aorta. The aorta is the bodies largest artery and blood is distributed to smaller arteries and out to the entire body (except the lungs).
Remember simply:
Body -> Vena Cava -> Right Atrium -> Tricuspid Valve -> Right Ventricle -> Pulmonary Semilunar Valve -> Pulmonary Artery -> Lungs -> Pulmonary Vein -> Left Atrium -> Bicuspid (Mitral) Valve -> Left Ventricle -> Aortic Semilunar Valve -> Aorta -> Body
If you can remember this, remembering heart anatomy and understanding how the heart works is very simple.
The path followed by the blood when it supplies and drains the heart muscle
Oxygen-poor, or deoxyginated blood starts in the right atrium, goes through the right atrioventricular valve and enters the right ventricle. It then goes through the pulmonary valve into the pulmonary trunk. It then goes through pulmonary arteries to the lungs, enters the capillaries in the lungs to pick up oxygen, then returns to the heart through the pulmonary veins and into the left atrium. This is the path of de-oxygenated blood
The general blood flow path is from the aorta to the heart. The blood will then leave the heart and flow throughout the rest of the body. This path of blood happens every time the heart beats.
the red blood cell will flow through your veins to your right atrium
The blood flows from the veins into the vena cava (inferior and superior) then into the right atrium. The right side of the heart sends the blood to the lungs to exchange carbon dioxide for oxygen.
pumping
Jesse you don't know how much i love you. Love your girl, Alyssa
it goes poo
The path that blood travels through is called the circulatory system. It includes the heart, blood vessels (arteries, veins, capillaries), and blood, which is pumped by the heart to deliver nutrients and oxygen to cells throughout the body and remove waste products.
i cnt trace it cuz this is a writing answer but the unoxygnated blood comes down through veins into the right atrium and out the right ventricle it passes the aveoli goes through the left atrium and out the left ventricle through the aorta and eventually into small capilaries

Pulmonary circulation is when the right ventricle contracts sending blood through the pulmonary artery to the lungs to get oxygenated, then back through the pulmonary vein into the left atrium.
