Veins

Thrombosis is the formation of a clot or thrombus inside a blood vessel, obstructing the flow of blood through the circulatory system.

Thromboembolism is a general term describing both thrombosis and its main complication which is embolisation1.

Pulmonary veins- which can be confusing because the blood in them is red and rich in oxygen since it just came from the lungs where it picked up O2. Vein drain to the heart. Arteries lead "A"way from the heart.

So the blood does attempt to flow downward from gravity. Low pressure system. ---- Blood flows through veins at a lower pressure and speed than in arteries. For this reason, valves are designed to prevent blood from flowing backwards. Venal blood returning to the heart from the legs, for instance, have the added task of having to fight gravity.

The pulmonary veins are the only veins in the body that carry OXYGENATED blood (from the lungs to the left atrium), and the pulmonary arteries are the only arteries in the body that carry DEOXYGENATED blood (from the right ventricle to the lungs).

The function of the vena cava is to return blood back to the heart.

Hot tea bag on infected area; if you are doing this without doctor's consent be aware that you could face criminal charges.

Hot tea bag or block of ice on infected area will help with swelling and any bruising. You will get a bulge in the muscle tissue but dont worry this should dissappear within a few days. You will still get high just that you wont get that initial all in one hit. It will just slowly take effect as it is absorbed. Its important to not have another shot straight away if you miss even tho your probably not feeling it because that shot is still in your system and if you have another one then you are doubling it.

The width/ diameter is the length form one wall to the other.

Harvey, observing the notion of the heart in living animals, was able to see that systole was the active phase of the heart's movement, pumping out the blood by its muscular contraction. Having perceived that the quantity of blood issuing from the heart in any given time was too much to be absorbed by the tissues, he was able to show that the valves in the veins permit the blood to flow only in the direction of the heart and to prove that the blood circulated around the body and returned to the heart. Fabricius, his teacher in Padua, had discovered the valves in the veins.

There are many possible causes of raised veins on hands. Generally is caused by the relaxing and thinning of the skin due to age. It can also be caused by a restriction of blood vessels in the hand.

the vein is melted♣original rEHEHusion are sediments or melted rock sPSSDSD

Green breast milk could be the result of a milk duct infection or merely a reflection of a change in the mothers diet. It is a good idea to consult a doctor, especially when accompanied by pain, nausea, fever, or chills.

Cardiac veins are blood vessels that carry deoxygenated blood away from the heart muscle. Included in these is the great cardiac vein, the middle cardiac vein, the anterior cardiac veins and the small cardiac vein.

A lot of the time when the weather is hot or the temperature changes, your veins may tend to rise closer to your skin. Your vein may hurt because it is touching other things in your hand. Your hand bruises because your vein might partly break and you might bleed under your skin. This is normal and do not worry. The pain will go away once the vein has found space or when it has gone down.

there are different things which could cause tingling in the face, for example the tension associated with migraine can commonly cause numbness and tingling due to pressure.

When men excersize continuously veins stick out and they are more green and notisable. The body temperature increases significantly so your body is trying to cool itself down it does it through many means by sweating and panting and sometimes through your veins so do mot worry your body is cooling you down.

Veins are a part of the human cardiovascular system. There job is to return blood back to the heart after the blood has circulated through the body by way of the arteries. The arteries, which carry the blood away from the heart, eventually divide into small capillaries, or tiny blood vessels, which diffuse oxygen originally from the heart into body cells. That blood then picks up wastes (including Co2) from those cells and returns to the heart through the veins of the body. The veins are found in all parts of our body. Some of the largest veins are the superior and inferior vena cava which are the last channels before oxygen-depleted blood reaches the heart. The jugular is the main vein that brings blood back from the brain.

Pulmonary veins are the exceptional veins because they are the only veins that transport oxygenated blood back to the heart. In the lungs, oxygen is diffused into small capillaries that branch off from one of the four pulmonary veins. The oxygenated blood in the pulmonary veins then enters the heart where it's later pumped back out of the heart again through the aorta (artery).

transports de oxygenated blood from the heart to the lungs to be oxygenated. On a side note, the pulmory arteries bring back the oxygenated blood from the lungs to the heart later to be pumped out of the left ventricle into the Aorta

Middle cardiac (and posterior vein of left ventricle) *both drain in coronary sinus*

Like all cells in our bodies, the cells in our eyes require oxygen and nutrients, and they need to eliminate waste. For many animals, transporting oxygen, nutrients, and cellular wastes is done using the blood vessels. So it only makes sense that we would have blood vessels in our eyes.

The great saphenous vein is a superficial vein that runs up the inside of the leg. It's the longest vein in the body.

Artery - always carries blood FROM the heart

Vein - always carries blood TO the heart

The vein which brings blood to the heart from the lungs is the PULMONARY VEIN ('pulmonary' = lungs). The one carrying blood away from the heart to the lungs is the pulmonary artery. Easy.

The superficial veins of the legs connect to the deep veins through "penetrating veins" which run perpendicular to the skin from one to the other.

The deep veins are essentially a column of blood running from your head to you feet and so when one is standing are under high pressure. In order to keep this pressure away from the frail superficial veins the penetrating veins have valves. When one of these valves goes bad the high pressure is allowed to go back to the superficial veins which blow up like balloons and become visible as what we call varicose veins (or "spider veins").
