Venous Plexus of the Pharynx Posterior

The pharyngeal venous plexus (or posterior pharyngeal plexus) is part of the human venous system and is responsible for collecting and draining blood from the posterior pharyngeal wall and surrounding tissues. The venous plexus consists of many small veins that connect to each other and form a complex structure.

The main function of the venous plexus of the pharynx is to maintain normal blood flow in this area. It collects blood from the back of the throat, tonsils, soft palate, back of the tongue and other tissues of the head and neck. In addition, the venous plexus also collects blood from the occipital and temporal regions, as well as the base of the skull.

An important aspect of the functioning of the venous plexus is its ability to maintain a balance between the inflow and outflow of blood. When blood flow increases, the veins dilate to accommodate the additional blood volume, and when blood flow decreases, the veins contract and compress to maintain normal blood volume.

In addition, the pharyngeal venous plexus also plays an important role in the body's immune system. It contains many lymphoid cells that are involved in protecting the body from infections and other pathogenic agents.

Thus, the venous plexus of the pharynx is an important component of the venous system and plays a key role in maintaining normal blood circulation in the head and neck.

Venous plexus of the pharynx posterior or posterior venous pharyngeal plexus, in contrast to the front, it is located on the lateral surfaces, and behind the body of the pharynx

Overlapping the bulb, the venous plexus of the pharynx is wide and strongly pronounced. They are connected to each other by a fan-shaped plexus that covers the body of the pharynx.

The posterior venous plexus of the pharyngeal canal brings blood from the back of the pharynx and through the posterior carotid vein it flows into the general venous system. It also supplies blood to the larynx
