What is path of blood flow in heart?

Answer 1

The deoxygenated blood enters the right atrium from the superior and inferior vena cava. The deoxygenated blood then goes through the tricuspid valve into the right ventricle. From the right ventricle the deoxygenated blood flows through the pulmonary valve to the lungs to be oxygenated. The blood goes to the lungs through the pulmonary arteries to get to the lungs. At the lungs diffusion (movement of things between a higher concentration and a lower concentration) occurs and the higher concentration of oxygen in the lungs (more specifically alveoli) goes to the lower concentration of oxygen in the capillaries (extremely small blood vessels). The same thing occurs with Carbon Dioxide except it is going from the capillaries from the lungs. The now oxygenated blood flows from the lungs to the left atrium through the pulmonary veins, where it is sent to the left ventricle through the mitral valve. From the left ventricle the oxygenated blood goes through the aortic valve, into the aorta, and all throughout out the body.

Answer 2

Into the right atrium from the superior and inferior vena cava, then into the right ventricle. From the right ventricle it goes into the pulmonary arteries to the lungs, then back through the pulmonary veins to the left atrium. It then goes to the left ventricle and gets pumped out of the aorta to the rest of the body.

Answer 3

the path of blood goes: right atrium, tricuspid valve, right ventricle, pulmonary arteries(drop off carbon dioxide and pick up oxygen from the lungs), pulmonary veins, left atrium, bicuspid valve, left ventricle, aorta, body and body cells, upper and lower vena cava, right atrium... duh:-)

Answer 4

Inferior vena cava to the superior vena cava to rt. atrium to rt. ventricle to the tricuspid valve to pulmonic valve to pulmonary artery to lungs to lungs to pulmonary veins to lft. atrium to lft. ventricle to bicuspid valve to aortic valve to the aorta

Answer 5

It first enters the heart through the top right atrium here it is pumped down to the right ventricle, here it is pumped through the pulmonary arteries, to the lungs to be enriched with oxygen, they then enter the heart through the pulmonary veins and into the left atrium, here it is pumped in to your left ventricle where it is then pumped into your aorta to be spread to the entire body.

Answer 6

into the right atrium from the superior and inferior vena cava, then into the right ventricle. From the right ventricle it goes into the pulmonary arteries to the lungs, then back through the pulmonary veins to the left atrium. It then goes to the left ventricle and gets pumped out of the aorta to the rest of the body.

Adding in the 4 heart valves and CS (Coronary Sinus) to the above answer.....

Return from Veins to Superior Vena Cava (from the brain) and Inferior Vena Cava (lower body) and Coronary Sinus (blood return from Coronary Arteries) => RA (Right Atrium) => (TV) Tricuspid Valve => RV (Right Ventricle) => PV (Pulmonary Valve) => PA (Pulmonary Artery) => Lungs => PV (Pulmonary Veins- Right and Left) => LA (Left Atrium) => MV (Mitral Valve) => LV (Left Ventricle) => AV (Aortic Valve) => Aorta => Arteries throughout body.

When the Aortic Valve closes during diastole (heart at rest; bottom number on BP), the blood flows backwards for a moment and enters the coronary arteries that lie just above the Aortic Valve. The blood then flows through the coronary arteries and then back to the right side of the heart via the Coronary Sinus. The blood that flows through the heart itself does not feed nutrients to the heart - the coronary arteries perform this function.

Answer 7

To summarise:

De-oxygenated blood arrives at the right atrium via the vena cava. Blood is then pumped into the right ventricle, then pumped via the pulmonary artery to the lungs where de-oxygenated blood is turned into oxygenated blood due to carbon dioxide (CO2) being exchanged for oxygen (O2). The now, oxygenated blood is brought back to the heart and into the left atrium via the pulmonary vein, blood is then pumped into the left ventricle, and is then pumped again up and through the aorta.

The blood then circulates around the body, and the whole process then starts again.

Hope this Helps!

Answer 8

Superior and Inferior vena cava, right atrium, tricuspid valve, right ventricle, pulmonic valve, pulmonary arteries, lungs, pulmonary veins, left atrium, mitral valve, left ventricle, aortic valve and through the aorta (vessel that flows blood to the rest of the body)

* Veins are vessels that are returning oxygen-poor blood to the heart. Arteries are blood vessels carrying oxygen-rich blood to the cells. In the case of the pulmonary veins and arteries, that distinction is reversed.
