Summary Introduction

To discuss:

The subclavian vein, brachiocephalic vein, and superior vena cava; landmarks that define the transition from one to another.

Introduction:

The veins are afferent vessels of the cardiovascular system; they carry de-oxygenated blood from the organs to the heart. They are also called as capacitance vessels, as they have a flaccid and thin wall. When compared with arteries, they accommodate 64% more volume of blood. The veins have low blood pressure than arteries and have a steady blood flow.
