Veins

The thick layer of a vein is made of collagen, wrapped in bands of smooth muscle while the interior is lined with endothelial cells called intima.

Elongated superficial dilated veins, are called Varicose veins.

The largest vein in the human body is the inferiorvena cava. The vena cava returns blood from the bottom half of your body back to your heart.

the pulmonary artery carries oxygen poor blood and the pulmonary vein carries oxygen rich blood. the arteries that carry blood from the placenta to the fetus, carry oxygen-poor blood amd the vein that goes from the fetus to the placenta carries oxygen-rich blood.

A vein tranfers clean blood from the heart through the whole body and since clean blood carries oxygen it helps transfer oxygen through the whole body too! ~Allyssa!

yes.it prevent the intermixing of oxygenated and deoxygenated blood

The facial vein is the main vein of the face. After receiving the supratrochlear and supraorbital veins, it travels obliquely downwards by the side of the nose, passes under zygomaticus major, risorius and platysma, descends to the anterior border and then passes over the surface of masseter. It crosses the body of the mandible, and runs in the neck to drain into the internal jugular vein.

the pulmonary vein?

I am not sure. I am trying to find that myself. Once I find it I shall tell you :)

Everyone has veins. Everyone has big and small. The reason some have bigger than others is the fact that genetics is strange. And also they have so little fat on their bodies that their veins seem to be bigger. Thats why sir.

Because they are closer to the surface. There could be other reasons.

Reconstruction of vena cava, but with angioplasty and stent. The description of the CPT reads, any method.

It could be phlebitis, which could be caused by an infection. An infection leading into the bloodstream could be life threatening if not treated. That is called "sepsis" or "septicemia". A less likely cause for the swollen and painful vein could be a clot, and clots in the circulatory system can potentially travel through the blood stream causing a blockage. Blockages to the heart, lungs, or brain can be life threatening.

On some areas of your body you can see your veins. It could be because you are hot, veins rise to the surface of your skin to cool you off. The same reason elephants flap their ears, it puts cool air on the blood and helps cool them off.

You have a stroke and die!!!!

The veins under the tongue often look really dark in color. The reason for this is because the skin under the tongue is very thin.

Stress because you tighten up. Make a fist right now and you will see your veins tighten. that's because you are stretching the vein and it applies pressure to the below muscle making it visible.
