Veins
Veins are thin blood vessels that carry blood from various body parts to the heart. These have valves in them to prevent back flow of blood.

When do veins carry oxygenated blood?
Only when it is the pulmonary vein, as it carries oxygenated blood to the heart. All other veins carry de-oxygenated blood which ends up going to the heart. (The pulmonary vein, however, comes from the lungs, where blood is first oxygenated and then transported to the heart.)
Why does it hurt throughout my arms and legs' veins when I sneeze?
Probably high blood pressure. You should have this looked at by your doctor and consider being put on blood pressure medication. Also, reduce sodium and caffeine intake and drink plenty of water.
Why do veins only have one way valves?
Veins have one way valves because the pressure in veins is lower than that in arteries, and the valves prevent backflow that could be caused by gravity or muscle flexure.
How many jugular veins are there?
2. the carotid artery and the jugular veins; they are located on opposite sides of the neck.
Which characteristics describes the blood carried by the pulmonary veins?
The pulmonary veins are the only veins in the body that carry oxygenated blood.
Like all veins the blood in the pulmonary veins travel toward the heart.
That means that the needle they were using to draw your blood when through the vein instead of stopping while in the vein( needed to collect the blood) and fluid leaked out around the vein. It will stop its own leak and will eventually heal itself. Ice will help the swelling for a short period.
Can you get air bubbles in your veins?

Why is blood usually drawn from vein of the left hand?
Becouse right hand is required for further work for the righty person.
What receives blood from the polumary veins?
The four pulmonary veins bring blood that has been oxygenated in the lungs back to the heart. They empty directly into the left atrium. Its is important to note that while most veins carry deoxygenated blood, the blood in these vessels are oxygen rich.
What two things help the blood in veins return to the heart?
The blood in veins is at a lower pressure than it is in the arteries. The lower pressure makes for challenges getting that blood back to the heart. As there is less force (pressure) in the veins, blood would pool in the lower parts of the body if there were not mechanisms to prevent that. There are three different things that help blood get back to the heart.
The three mechanisms are: venous valves, muscular pumps, and the respiratory pump.
Why you can live without the saphenous vein?
Look up collateral circulation. The saphenous vein is a superficial vein, so it primarily works to cool/warm the body. It is fed by veins that are deeper in your leg, so when you remove the saphenous vein the other veins find a different path to go around (collateral circulation). Once this vein is removed (typically for Bypass surgery, but potentially for varicose vein treatment) the person's leg tends to be "fatter" or "swollen". Ironically, some medical sources indicate that the swelling subsides, but in practice I can tell you that is seldom the case. None the less, a fatter left, or right leg is better than a still heart.
What chamber receives Oxygen-rich blood from the pulmonary vein?
The left atrium receives the blood carried from the pulmonary veins.
Why do veins become more prominent as one ages?
Because the skin thins to paper thin on the outer body as well as tissues in the inner body, not to mention muscle loss. The heart has to pump harder as we get older, thus we really see the veins stick out. Think of a body builder ... look at those veins! They have always been there, but when younger we don't notice them as much. As we age, the tissue in out body loses its elasticity. Veins and arteries start to stretch, and have a larger cross section. The skin also loses elasticity and becomes 'floppy', allowing the veins to show through more readily.
What Vein is borrowed for cardiac bypass surgery?
Great Saphenous vein is "borrowed" for cardiac bypass surgery
no, you just have a pale complexion complimented by general translucence of the epidermis.
The blood going out from the arteries is full of oxygen. It delivers that oxygen to the organs, therefore when it returns in the veins, it contains carbon dioxide
