Deoxygenated blood enters the right atrium via the vena cava, then passes through the tricuspid valve to the right ventricle. The blood is then pumped via this ventricle via the pulmonary arteries to the lungs to pick up oxygen. Oxygen-rich blood returns to the left atrium of the heart via the pulmonary veins and passes via the mitral valve to the left ventricle. This powerful pump then sends the blood through the aortic valve to the aorta and on to the entire body to nourish all living tissue and cells

How the human heart could compensate for flow rate changes to maintain blood pressure?

What Valves inside the veins prevent blood from flowing from the heart?

The blood in veins is not under direct pressure from the heart. It has little valves inside to prevent blood from flowing backwards away from the heart. These valves inside the veins prevent the backflow of blood in veins. They encourage the one-directional flow of blood to the heart.

Heart valves help prevent blood from flowing backwards through the chambers of the heart. They open only one way to allow blood to flow through to the next chamber, and close against flow of blood from the other directon.


What are the dangers of blood clots?

Clots inside the blood vessels block the flow of blood to major organs and cause heart attacks and strokes.


Does blood keeps the heart pumping?

not entirely, if the blood flow stops,so does the heart, but the heart is mainly used to keep the blood flowing so it can get to different parts of the body. Electricity can keep a heart pumping if the correct amount of flow is being produced so blood can be replaced for the heart but cannot sustain a human body.
