When a valve doesn't completely close such as in the disease Mitral valve stenosis blood is allowed to black flow and pool in chambers which makes the heart work less effectively.
No i don't think so .
Veins carry deoxygenated blood back the heart.
The arteries and veins are the tubes that are connected to the heart. Arteries carry blood away from the heart, and veins carry blood to the heart.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
The veins carries blood from the body to the heart.
Veins return blood to the heart.The pulmonary veins.
because valves prevent this action
because valves prevent this action
because the heart have valves
Veins transport deoxygenated blood from the body to the heart. They also prevent the backward flow of blood. The pulmonary vein, as an exception, transports oxygenated blood from the lungs to the left atrium of the heart.
valves in the veins
Blood is a constant whereabout in our bodies. As of such a frequent heartbeat exists within our system. Which causes the blood within our bodies to flow forward, in lamense terms it produces a very large push for the blood to distribute it's nutrients throughout the body and back within our heart and out again. This constant push is what prevents blood from flowing backwards in your veins.
Blood flows away from the heart in arteries, and towards the heart in veins.
Veins carry deoxygenated blood back the heart.
veins, maybe
The heart, the blood vessels - arteries, capillaries, and veins are five part of the cardiovascular system. Heart help moves blood throughout your body. The blood vessels help blood transport through body, even in or out of the heart. Arteries is the blood vessel that help carries blood away from the heart. The major function of capillaries tubes is that they connect arterioles to venules. As blood travels through veins, valves in the veins help kepp the blood from flowing backward.
