Body Anatomy and the Veins of the body

This is a tutorial on some of the important veins of the body. So I’m going to start at the heart and then work outwards and talk you through some of the important veins that you should know.

This is the right atrium and this is the right ventricle of the heart.

Deoxygenated blood returns to the heart, to the right side of the heart via the venous system. So this vessel superior to the right atrium is called the superior vena cava and below, you’ve got the inferior vena cava.

You can see the inferior vena cava running all the way down to the pelvic region where it splits.













The superior vena cava forms from these two branches. You can see that these vessels lie behind the clavicle. This and the breastbone, which I’ve removed here would lie anteriorly here.
The superior vena cava is formed from these two veins which drain into it and this is the brachiocephalic veins. So you’ve got the right and the left brachiocephalic veins.

This vein, which arches over here and runs underneath the clavicle is called the subclavian vein because it runs underneath the clavicle. So sub- meaning ‘under’, –clavian referring to clavicle.

Yyou’ve got the subclavian vein draining into the brachiocephalic vein, which joins with the other brachiocephalic vein to form the superior vena cava.

Also, then you’ve got these two vessels here, these two veins, which are coming down from the brain and the head.

This one, which is more medial is the internal jugular vein and this one, which is more lateral is the external jugular vein. The internal jugular vein drains the vein and the external jugular vein drains the head and face.
The External jugular

This external jugular vein comes and drains into the subclavian vein and where the internal jugular vein drains into becomes the brachiocephalic vein. So where it drains into the subclavian, it becomes the brachiocephalic brain.
