POSTCAVA Meaning and
Definition
-
The term "postcava" refers to one of the major blood vessels found in the circulatory system of vertebrates, including mammals and birds. It is also known as the posterior vena cava or the caudal vena cava. The postcava is responsible for returning deoxygenated blood from the lower regions of the body and various organs back to the heart.
In humans, the postcava starts at the level of the fifth lumbar vertebra by the convergence of the two common iliac veins. It ascends through the abdominal cavity, receiving blood from the lower limbs, pelvis, and abdominal organs, such as the liver and kidneys, before entering the right atrium of the heart. Along its course, the postcava receives multiple tributaries, including the lumbar veins, renal veins, ovarian/testicular veins, and hepatic veins.
The postcava plays a crucial role in maintaining proper blood circulation and oxygenation. It acts as a conduit for deoxygenated blood to return to the heart, where it can be sent to the lungs for oxygenation before being pumped to the rest of the body. By efficiently collecting blood from various organs and regions, the postcava ensures the continuous flow of blood throughout the body, allowing for proper nutrient delivery, waste removal, and maintenance of homeostasis.
In summary, the postcava is a major blood vessel that returns deoxygenated blood from the lower body and various organs to the heart, facilitating proper circulation and oxygenation in vertebrates.
