Why do veins pop out your arm?

Answer 1

Your veins pop out for many reasons

1. You may be slightly muscular therefore the muscules push the veins up and out

2. Like me your veins may be close to your bone so when you move the bone they pop out

3. There isn't enough blood flow going through them

Hope this helps XD

Answer 2

Veins can bulge into the skin when they are containing the pressure of blood flow. The vessel walls expand until the blood can flow out through one-way valves on the path back to the heart.

Veins normally bulge when they are "lower" than the heart, because there is no pumping action to force the blood out. Raising an extremity (arm or leg) will normally reduce the pressure sufficiently that the vein will contract back into the exterior muscle tissue.

Answer 3

Veins in general pop out of your skin when your body is hot because your veins are trying to cool off. if you ever notice when your cool your veins hide and are not visible to the eye because the veins are trying to keep your blood the correct temperature. so when your overheating the veins in your head pop out to cool down.

Answer 4

They do on muscular hands, when hands have been working or have had extra pressure on them, or when the skin becomes frail/translucent usually due to old age. It has to due with how much blood (and at what pressure) is pumping through the veins and/or how much skin (with necessary proteins) is covering the hand.

Answer 5

Blood is pumped from the left ventricle of the heart throughout the body. Blood first enters arteries then to smaller branches of low-pressure arteries called arterioles, then to the smallest structures called capillaries. Capillaries nourish and remove waste products from cells. Blood pressure at the time blood enters capillaries is very low. From capillaries, very-low-pressure blood flows back to the heart via venules, so they eventually combine with larger veins.

Answer 6

The veins in arms and legs are closer to skin surface,some people have more prominent visable veins than others.

Answer 7

If a persons veins are out or visible it usually represents good circulation.
