What is pulmonary Artery and Vein?
The Pulmonary Artery is the only artery in the body to carry deoxygenated blood from the Heart to the lungs where it "picks up" Oxygen and "Drops off" Carbon dioxide by the process of Diffusion through the 1 cell thick air sacks in the lungs. The Pulmonary Vein is the only vein then to bring oxygenated blood anywhere in the body, the oxygenated blood goes to the Left hand side of the heart (think about it as if you were personally looking down at your own heart, not as a diagram) then the left hand side of the heart pumps it around the body through the aorta.
What is the function of the arcuate vein?
drain blood from the interlobular veins, and empty into theinterlobar veins
Why Veins carry purplish blood but you do not bleed a bluish-purple blood when the vein is cut?
Veins appear blue because light, penetrating the skin, is absorbed and reflected back to the eye. Since only the higher energy wavelengths can do this (lower energy wavelengths just don't have the *oomph*), only higher energy wavelengths are seen. And higher energy wavelengths are what we call "blue." Blood is never purple although deoxygenated blood is a deeper shade of red than fully oxygenate blood.
What is a liquid that runs through an animal's body through veins an arteries?

What is retinal vein occlusion?

What is the function of the superior pulmonary vein?
The superior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart.
Cross sectional area of veins is four times that of arteries This large cross sectional area plus large degree of compliance (yielding to pressure) implies that large amounts of blood can be stored in the veins with only minimal increase in pressure.
How are varicose veins treated by sitting down?
Other measures are sitting down, using a footstool when sitting, avoiding standing for long periods of time, and raising the legs whenever possible. These measures work by reducing the blood pressure in leg veins.
How much would laser treatment for vaicose veins cost?

Where on the human body is the best place to draw blood?
On the inside of your elbow, where your arm bends and straightens.
How is blood pressure maintained in veins to cope with the force of gravity?
The amount of venous vessel pressure causes the 'venous return' which maintains blood volume. This is driven by the efferent pathway of the sympathetic nervous system which causes the constriction of the blood vessels which pushes the red blood cells in the veins back to the heart (flow is one way due to valves in the veins).
The main vein draining blood from the heart tissue is the?
Great Cardiac Vein. It, along with the middle and small cardiac veins return blood to the coronary sinus which returns the blood to the right atrium. A few small anterior cardiac veins return blood directly to the right atrium.
When do veins functions as blood reservoirs?
Hi, veins function as a blood reservoir as they carry the blood, this giving them the name (reservoir)
