Vascularity, in bodybuilding, is the condition of having many highly visible, prominent, and often extensively-ramified superficial veins. [1] The skin appears "thin"—sometimes virtually transparent—due to an extreme reduction of subcutaneous fat, allowing for maximum muscle definition. [citation needed]
They use near-infrared light reflection to create a map of the veins. [1] The received imagery is then either displayed on a screen or projected back onto the patient's skin. They may not increase the success of starting intravenous catheters in children, [ 1 ] since the difficulty may arise not in locating the vessel , but in physical ...
Veins become more visually prominent when lifting heavy weight, especially after a period of proper strength training. Physiologically, the superficial veins are not as important as the deep veins (as they carry less blood) and are sometimes removed in a procedure called vein stripping, which is used to treat varicose veins.
The veins will empty due to gravity or with the assistance of the examiner's hand squeezing blood towards the heart. [citation needed] A tourniquet is then applied around the upper thigh to compress the superficial veins but not too tight as to occlude the deeper veins. The leg is then lowered by asking the patient to stand. [citation needed]
The capillaries connect to venules, and the blood then travels back through the network of veins to the venae cavae into the right heart. The micro-circulation — the arterioles, capillaries, and venules —constitutes most of the area of the vascular system and is the site of the transfer of O 2 , glucose , and enzyme substrates into the cells.
Varicose veins and reticular veins are often treated before treating telangiectasia, although treatment of these larger veins in advance of sclerotherapy for telangiectasia may not guarantee better results. [18] [19] [20] Varicose veins can be treated with foam sclerotherapy, endovenous laser treatment, radiofrequency ablation, or open

The peripheral vascular system is the part of the circulatory system that consists of the veins and arteries not in the chest or abdomen (i.e. in the arms, hands, legs and feet). [1] [2] The peripheral arteries supply oxygenated blood to the body, and the peripheral veins lead deoxygenated blood from the capillaries in the extremities back to ...
