Movement of BLOOD through veins & arteries?

Question

What causes the movement of blood through the Arteries?........................ Veins?

Answer 1

All of the parts of your heart, like the chambers and valves, work together to ensure that blood always flows on the same path on its way through your heart and lungs.

Blood flows through each chamber one time on its way through your heart — first through the right side of your heart and then through the left.

Blood doesn't flow by itself — your heart's chambers work hard to keep blood moving. The chambers relax and expand to let blood flow into them. Then they tighten and pull inward (contract) to help push blood out.

You might hear your nurse talk about your diastolic pressure or systolic pressure when you get your blood pressure checked. When a chamber is relaxed, or expanded, it is in diastole. When a chamber is contracted, or small, it is in systole.

Answer 2

Also known as the cardiovascular system, the system that, in humans and other higher animals, delivers oxygen and nutrients throughout the body by a complex network of vessels – arteries, arterioles, capillaries, veins, and venules. Arteries, arterioles and the microscopic capillaries carry blood away from the heart to all parts of the body and allow exchange of nutrients and wastes through capillary walls from blood to the tissues and organs. Veins carry deoxygenated blood back to the lungs for reoxygenation. If all the vessels of this network in an adult human body were laid end-to-end, they would extend for about 60,000 miles (more than 96,500 kilometers) – far enough to circle the Earth more than twice.

Answer 3

Oxygenated blood flows from the lungs to the left atrium contractions (heart muscle) cause the blood to leave the atrium and enter the left ventricle. Further contraction causes the blood to leave the atrium and enter the aorta. Under the pressure created by the continuously beating heart, the blood flows through the aorta (major artery), reaching the point where the aorta branches off towards the upper body (face, neck brain etc) and the lower body. The diameter of the aorta gradually decreases as blood flow is directed to tissue and organs, flowing through arteries then the smaller arterioles then the capillary beds at the target organ, tissue, etc. Here the oxygen is liberated to the tissue and the blood picks up the resulting CO2. This oxygen poor blood travels from the veins leading out of the capillary beds into venules and travels up through progressively larger veins until it reaches the Inferior (from lower part of body) or Superior (upper body) vena cava. The blood then enters the right atrium, is pumped to the left atrium, which pumps it through the pulmonary artery to the lungs where the CO2 is exchanged for O2 This Oxygen rich blood is then sent through the pulmonary artery to the left atrium, and the process continues. It really is easier to visualize it. See if the diagram below helps.

Answer 4

The heart pumps bloods throughout the body and back.

Answer 5

It is a muscle called the heart

Answer 6

For most of us it is the Hart. Vampires would be another matter.

Answer 7

That would be the heart.

Answer 8

air pressure
