Radial Vein

The upper limb has a venous drainage that includes a superficial system as well as a deep system. The superficial system empties towards the deep system. Within the forearm The radial veins are paired veins which go along with the radial artery. The veins of the deep system go along with the arteries, and are called venae comitantes. Commonly, the veins which go along with the arteries are in sets, and are therefore often described in the plural type venae comitantes.

Origin

The radial veins emerge via the deep palmar venous arch and attach the ulnar veins in order to empty within the paired brachial veins. The radial vein begins within the hand and adheres to the route of the radial artery. It travels on the lateral part of the forearm and splits it within an anterior (front) as well as a posterior (back) part.

Insertion

In the hand it travels in between the heads of the adductor pollicis muscle and after that to lay on the outer part of the forearm via the anatomical snuff box. To create the brachial vein the radial vein connects the ulnar vein from the opposite side. They travel the length of the forearm simply under the elbow, and also trail the path of the radial bone. Their path is likewise rather equivalent to the radial arteries. These veins help in emptying oxygen-depleted blood through the hand and forearm. In this procedure, the blood streams to the brachial vein and in order to get resupply with oxygen ultimately makes its way back towards the lungs and after that to the heart for recirculation.

Function

The radial artery brings deoxygenated blood via hand and the forearm, which receives oxygenated within the lungs. They empty this deoxygenated blood within the brachial vein which eventually carries the blood towards the right part of the heart. Then after travelling through the lungs it is recirculated in the entire body by left side of the heart.
