Superior Vena Cavas (plural noun) refer to the two large veins that carry deoxygenated blood from the upper body back to the heart. These veins are essential components of the circulatory system and play a crucial role in maintaining blood flow and circulation.
The superior vena cavas are the largest veins in the body and are located in the chest region. They emerge from the junction of the major veins in the upper body, including the jugular veins, subclavian veins, and occasionally the azygos vein. Their primary function is to collect deoxygenated blood from the head, neck, upper limbs, and chest, and return it to the right atrium of the heart.
Superior vena cavas are responsible for transporting deoxygenated blood, rich in waste products and carbon dioxide, towards the heart to be replenished with oxygen. From there, the blood will continue its journey through the pulmonary circulation, where it undergoes oxygenation in the lungs.
In situations where there is an obstruction or constriction in the superior vena cavas, blood flow back to the heart may be impeded. This can lead to symptoms such as swelling in the upper body, difficulty breathing, and changes in blood pressure. In some cases, medical intervention might be required to address the underlying issues affecting the superior vena cavas and ensure normal blood flow.
