Inflamation
Veins as seen through tissue are normally sort of a greenish-blue color.
Because they are closer to the surface. There could be other reasons.
There is nothing different about the veins in their arms. It's actually dependant on how pale their skin is. The paler your skin is, the clearer you can see the veins in your arms, apart from that, there is no difference between people with "veiny" arms and "non-veiny" arms.
Well veins are always good.. You always need them to have blood move around your body but if you mean.. "Is it alright if the veins are popping out or big when you workout?" then the answer is yes its normal to have them popping out during workouts... When you workout your arms blood goes there and the veins get bigger to deliver the blood faster to your arms.. i hope this helps
The restriction of blood to your arm will cause you numbness (to fall asleep). This happens when something is pushing on your veins, either your muscles or for example if you fall asleep on it.
If you're over 40, you probably see them; those little purple veins that suddenly seem to appear on your legs. Veins are the soft, thin-walled tubes that return blood from the arms and legs to the heart. Because veins work against the force of gravity, they have valves that allow forward blood flow, but not reverse. Your legs and arms have two major types of veins: superficial and deep. The superficial veins are near the surface of the skin and are often visible. The deep veins are located near the bones and are surrounded by muscle. Connecting the deep and superficial veins is a third type of vein, the perforator vein. Contraction (squeezing) of the muscles in the arms and legs with exercise helps blood flow in the veins.Varicose veins are enlarged, bulging superficial veins that can be felt beneath the skin, generally larger than 3-mm in diameter. They are usually located on the inside of the calf or thigh and develop due to weakness of the vein wall and loss of valve function. Under the pressure of gravity, they continue to enlarge, and in the course of time, they may become elongated, twisted, pouched, and thickened.Spider veins or telangiectasia are tiny dilated, veins, usually less than 1-mm in diameter, located at the surface skin layers. Spider veins cannot be felt. Veins larger than the spider veins, but still under 3-mm are called reticular veins.
Eat fatty foods only & do not exercise.Your arms will get bigger, so will the rest of you.If you are looking for big arms to show the girls....exercise using weights.
Because the blood is moving inside them
Arms are attached to the shoulders by ligaments and muscles. Veins and arteries pass through from the neck and chest to each arm.
Basillac veins are located in the subcutaneous fat of upper limbs, ie human arms. They help drain blood from the hands and forearms.
Veins can be found in different parts of the body. Veins in the hands called metacarpal veins, median arch vein, basilic, ulnar vein, brachial, veins in the feet and the back, near gastronemius muscle.
Generally, arteries, veins and capillaries. In the arm, some examples would be the axillar, brachial, radial and ulnar arteries. Veins could include the cephalic and median cubital veins.
