Veins

My veins pop out as well it means you either have low body fat or if your muscle is more than the fat in that area

It is formed through millions of years of pressure cement ton of minerals together, crystallizing and forming certain ores. blah

To and from the heart. in/out the ventricles and the atriums.

the vein thats most subjected to venipuncture is located in the Antecubital fossa (the inner bend of the elbow) in the median antecubital vein(median cubital)

A dorsal vein in the hand is one. Most commonly, for blood draws in a lab, the antecubital vein (at the location opposite where the elbow flexes, between the forearm and the upper arm) is used.

1. Valves in the veins which stop blood flowing backwards

2. As the muscles around the veins contract (from general activity eg walking) they squeeze the veins, therefore forcing blood back to the heart (in just that direction because of valves)

Tortuous, swollen veins in the distal esophagus are called esophageal varices. They are caused by portal hypertension, or elevated pressure in the portal circulation. Esophageal varices can cause severe internal bleeding.
Esophageal varices are varicose veins at the end of the esophagus.

Six hours or more of inactivity. Or at least that's what some squirrel told me but it can't be true because you sleep for six hours every ngiht.

No. If a vein is blown it can no longer be used for an injection.

nothing, if you press it for a long period of time you may loose blodd circulation

Varicose veins can occur anywhere in the body, but are more commonly found on the legs.

blood. It is a blood vessel but more specifically a vein. Note there are two: superior vena cava (from upper part of body) & inferior vena cava (coming from lower part of body). They carry oxygen-poor blood back to the heart's right atrium then on to the lungs via the pulmonary artery to exchange carbon dioxide for fresh oxygen.

normal blood flow in portal vein and patent portal vein is a sign of the normal physiological condition of liver blood web and clearness of portal venous way

Some foods that known to improve blood circulation are salmon, goji berries, oranges, avocados, and lemons. Other foods on the list are dark chocolate, garlic, ginger, and watermelon.

== == The eye has been irritated by something. Redness is a sign of a unhappy eye, one that has been exposed to too much of something, such as dust, wind, lack of sleep, or too much alcohol drinking. Other causes could be exposure to welding flash, chemical fumes, or even harsh shampoo or soap. Treatment is simple.........warm water bath of the eye, with repeated applications of warm water. Cover the eye, and rest in a dark place, with BOTH eyes closed for an hour at least. Conjunctivitis is the technical term for red eyes. It can also be the result of allerfies, a virus like a cold, or caused by a bacteria like "Red Eye," an irritation or injury, or a serious infection. If you wear contacts remove them until the condition is entirely cleared up. If you normally wear eye makeup, discontinue and discard it. I would use eye drops rather than plain water. Often children bring bacterial "Red Eye" home from school with them. It is spread by hand contact, and can effect all members of the family. Red eye is characterized by redness and a discharge from the eye. Your family doctor can treat Red Eye with mild antibiotic drops. If the condition persists more than 1 day, or you have pain, or the eye tears excessively or is sensitive to light, or the redness is growing worse, I would see an optometrist ASAP. Don't trust your family doctor to treat eye conditions. I did, and almost lost an eye because he mis-diagnosed a serious eye infection as "just irritation from your contacts."

Every phlebotomist hopes to see large, prominent veins that are easily visible just below the surface of the skin. Veins with an elastic (sometimes described as a 'bouncy') quality usually indicate large, healthy veins that are less likely to collapse.

The medial cubital or cephalic veins are the most common veins used in venipuncture. Veins which are fibrosed, fragile or inflamed should be avoided.

The femoral vein is the main vein in a human leg.

The great saphenous vein is the superficial vein on the medial side of the tibia. It is the longest vein in the body.

the total blood flow is controlled by the number of capillaries that are open at any given moment, so outside the tightening and loosening of those muscles ... very little.

The veins become slightly distended and the arteries empty a bit quicker.

At rest about 20% of the capillaries are open at any given time.

Cephalic

The blood in veins appear green on the skin because the skin serves as a filter for the color red which perceives the color as green. Under normal light, blood appears as a red color.
