What do your veins in the heart do?

Answer 1

The basics: Your heart pushes blood through arteries. The further away from the heart the less pressure. Veins are used to transport waste and 02 poor blood back to the heart. This is through some pressure from the heart but generally skeletal muscle contraction. Especially in the legs when walking. As the blood moves up, there are little one way valves to keep the blood from flowing backwards. The last factor in moving the blood is gravity. Like blood returning to the heart from your head.

Answer 2

The veins carry blood with carbon dioxide back to the lungs (Deoxygenated blood), and the arteries carry oxygen (oxygenated blood) to the muscles and blood to blood vessels and etc.
Arteries conduct blood from the ventricles of the heart to the capillary beds while veins conduct blood from the capillary beds to the atria of the heart. Portal systems are an exception to this generalisation, e.g. the hepatic portal vein and the portal system of the pituitary; these conduct blood from one tissue bed to another and not to or from the heart directly.

Answer 3

veins carry bundles of tubes that carries water and minerals to stem and roots it also carries water to leaves.

Answer 4

Veins bring deoxygenated blood back to the heart. Only the pulmonary veins bring oxygenated blood back to the heart from the lungs.

Answer 5

little valves
