Veins

deoxygenated blood

Not deep at all, which is why emos and other weepy attention-whoring types focus so much energy on the area.

Just remember, it's "Down the lane, not across the road".

^ Fu! weepy attention-whoring?! Some people have serious problems! You dick.

Sore veins in your hand won't cause a disease.

Temperature has little, if anything to do with vein visibility. You can see veins at any given time (usually), if you look at your wrist or anyplace the skin is thin.

Oxygen rich - the opposite of what the majority of veins are in the body.

Empties into coronoary sinus which empties into the right atrium

If they are big and kind of stick out a little, they might be varicose veins. Lower extremity veins normally have valves in them to help pump blood from the legs back to the heart. In varicose veins, these valves have stopped working. Varicose veins can be potentially dangerous and can lead to blood clots. I'm pretty sure surgery is the only fix.

This is because one side (the left) is for pumping blood from the heart to the lungs, where it receives oxygen. This blood is then pumped to the rest of the body through the other side of the heart (right) where the oxygen nourishes the rest of the body. This blood then returns to the left side of the heart, to be pumped to the lungs to receive more oxygen and so on.

Note that each side of the heart (right and left) also contains two chambers - an atrium and a ventricle (so the heart is made of four chambers in total). Blood entering the heart passes into the atrium, then on to the ventricle, and then on out of the heart.

name the movement of veins are assisted by

pulmonary vein

If you eat a lot of salt or sour stuff at once that can happen. If not see a doctor?

Your skin is like your body's air conditioner. When it is hot, you "open" your vents (dilate blood vessels). When it's cold, you close it up (constrict, which gives your skin a "bluish" appearance). If you are golfing, you are using a lot of energy in your legs creating a lot of heat. Therefore, your body will open up those "vents" the most.

The medial cubital or celphalic

After it passes through the kidneys and arcuate vein would enter into the inferior Vena Cava.

Inject it.

Arterial flow means the blood flow is moving towards the heart, whereas a vein flow is when the blood moves away from the heart.

atrium

The inferior vena cava is one of two veins which carries deoxygenated blood from the body into the right atrium of the heart.

There is one 'vein' that runs the length of a prawn, it should not be eaten, it is it's digestive tract, (It's guts).

The deep veins of the forearm are the venæ comitantes of the radial and ulnar veins and constitute respectively the upward continuations of the deep and superficial volar venous arches; they unite in front of the elbow to form the brachial veins. The radial veins are smaller than the ulnar and receive the dorsal metacarpal veins. The ulnar veins receive tributaries from the deep volar venous arches and communicate with the superficial veins at the wrist; near the elbow they receive the volar and dorsal interosseous veins and send a large communicating branch (profunda vein) to the vena mediana cubiti.
