SUBCLAVIAN VEINS Meaning and
Definition
-
The subclavian veins are large blood vessels located in the upper chest region that play a crucial role in the circulatory system. They are paired veins, meaning that there is one on each side of the body. The subclavian veins are responsible for draining deoxygenated blood from the upper limbs, as well as certain areas of the head and neck.
Originating from the brachiocephalic veins, the subclavian veins receive blood from the corresponding upper limbs via smaller veins known as the axillary veins. These veins merge with the internal jugular veins to form the brachiocephalic veins near the base of the neck. The subclavian veins then continue their course to connect to the superior vena cava, which is the largest vein in the body, responsible for carrying deoxygenated blood from the upper body to the heart's right atrium.
The subclavian veins are essential for maintaining proper blood circulation and facilitating the return of deoxygenated blood from the upper extremities to the heart. They are encased in muscle, connective tissue, and bone structures, providing protection against external forces. Their location close to major arteries and nerves in the upper chest allows for efficient delivery of oxygen-depleted blood while also playing a role in regulating body temperature.
In summary, the subclavian veins connect the upper limbs, head, and neck to the superior vena cava, ensuring the return of deoxygenated blood to the heart.

Etymology of SUBCLAVIAN VEINS
The word "subclavian" has its roots in Latin. It comes from the combination of two Latin words: "sub" meaning "below" or "under", and "clavis" meaning "key". This term was used to describe the position of something below or under the key bone.
The term "veins" originates from the Latin word "vena", which simply means "vein".
Therefore, "subclavian veins" refers to the veins that are located below or underneath the clavicle (collarbone). These veins are major blood vessels that carry deoxygenated blood from the upper body back to the heart.
