Can you see any veins for transporting water?

What aftercare is required with portal vein bypass?
Patients receive pain medication and antibiotics . Once released from the hospital, patients are expected to abstain from alcohol and to follow a diet and medication schedule designed to reduce the risks of bleeding.
Is blood is transferred from arteries to veins through capillaries?
Yes of coarse Arterie= oxygenated blood
Vein= deoxygenated blood
Capillarie= link to the vein from arterie
What is carotid artery occlusion blockage?
Carotid artery occlusion blockage means that there is complete blockage of the artery. This is very serious, as complete blockage of the artery can cause a stroke.
Which procedure coagulates blood inside a varicose vein to collapse and seal it?
The procedure is call Endo Venous Laser Therapy and uses a small bore fiber optic to deliver laser energy to the internal structure of the blood vessel. The procedure is outpatient and only requires a local anesthetic. Several visits may be required to correct the problem.
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 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?
Laser treatment for vaicose veins can range in price greatly. Depending on the amount of work being done, costs can be from $400 USD all the way up to $3200 USD.
Veins are blue in color, they carry deoxygenerated blood which has greater absorption coefficient than the oxygenated blood that runs in artery which is mainly responsible for the blue color.
