Blood in veins is sent to the heart to get oxygen.
Veins are where you will find deoxygenated blood that is returning to the heart to be sent to the lungs.
Veins
Veins return blood to the heart.The pulmonary veins.
Varicose veins form when blood pools in the veins.
blood doesn't 'flow backwards - there are valves in the veins and arteries to stop that happening. Oxygenated blood is sent from the lungs, via the heart - to all parts of the body. When the oxygen has been used up by the cells, the blood returns to the hart through the veins.
Veins carry dirty blood or blood with carbon di oxide. Arteries carry blood with oxygen to all parts of the body. The veins carrying dirty blood are finally sent to the lungs where they give up the carbon di oxide and take in oxygen for circulation.
veins are blood vessels
because you blood is inside your veins.
The venous system, or "veins" are responsible for bringing blood back from your peripheral body to the right side of the heart, where it is sent to the lungs for reoxygenation. Veins have one way valves that function to maintain a stable pressure in the venous system, while increasing the efficiency of the heart by preventing backflow of blood in between ventricular beats.
blood vessels that carry blood toward the heart are called veins.
Veins have valves in them which help transport the blood.
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
