Blood circulation through the heart starts at the Vena Cava, where the deoxygenated blood goes into the heart after going through the body. The deoxgenated blood travels throught Right Atrium, through the Tricuspid Valve and into the Right Ventricle. From there, the blood goes through the Pulmonary Semi Lunar Valves into the Pulmonary Arteries and out to the lungs. At the lungs the blood will pick up oxygen. After being oxygenated the blood then goes back into the heart throught the Pulmonary Veins. Then the oxygenated blood goes into the Left Atrium, through the Bicuspid Valve and into the Left Ventricle. Finally, the blood goes through the Aortic Semi Lunar Valve, into the Aorta and out to the body.
The blood goes through the heart in the correct direction because there are a number of one-way valves in the heart chambers that blood can only pass through in the correct direction.
The capillarys are in the lungs and blood flows trough them.As far as I know, blood does not flow back through the capillarys so it most likely does not flow back through the capillary beds.
The heart pumps the deoxygenated blood trough the right side of it and out trough the pulmonary artery which connects to the lungs.
Yes, blood flows into the heart via veins. Blood flows away from the heart in aryteries.
Connective tissue flows through the heart and blood vessels.
Blood that flows from the lungs to the heart is oxygenated, so it's bright red. In contrast, blood that flows from the heart to the lungs is deoxygenated, and so is dark red.
Blood flows back to the heart through the veins.
blood flows by the heart pumping
Blood
Blood flows from the heart into the left atrium, into the left ventricle. From there, it flows from the right artrium into the left ventricle.
The blood flowing through the veins carry the carbon dioxide from the cells of all parts of the body to the heart. Hence we say that the veins transmit the De-oxygenated blood from all parts of the body to the heart. The De-oxygenated blood collected in the heart flows to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs. Then the oxygenated blood flows to the heart through the pulmonary vein. Then the oxygenated blood flows to all parts of the body through the arteries. So blood flows into the heart through the veins, and flows out of the heart through the arteries. Normally the De-oxygenated blood flows through the veins and the oxygenated blood flows through the artery. The only exceptions are the pulmonary artery that transmits de-oxygenated blood from heart to the lungs and the pulmonary vein that transmits oxygenated blood from lungs to heart. This is because blood flows into the heart by veins and flows out of the heart by arteries.
From the capillaries blood flows to the venules to the veins to the vena cava to the heart (right atrium).
