What Are Venae Cavae?
The venous blood vessel cavae are a pair of largest veins in the dead body . There are two venae cavae which are the superior vena cava and the deficient venous blood vessel cava . The function of these veins is to transport deoxygenated blood from different parting of the body to the core . This deoxygenated blood is then transported through the pneumonic arteria to the lung where the blood gets oxygenated and send back to the heart from where it is transported back to all parts of the dead body through the aorta .
The oxygen channelise to the vital organ of the torso is then consumed and exchanged with carbon dioxide and the same deoxygenated blood is again carry to the heart through the superior and subscript vena cava . The superscript vein cava is located in the upper thorax and is constitute by brachiocephalic vein while the deficient venous blood vessel cava is situate in the back region of the soundbox and runs along the spine and parallel to the aorta .
Anatomically address , the wall of the vena cavae are made up of three layer of tissues . The knocked out stratum is composed of collagen and flexible fiber tissue . This bed makes the vena cava warm and pliant . The middle layer is made up of tranquil musculus . The third bed is made up of endothelium lining . This lining preclude the platelets from cluster together and allows free rate of flow of blood through the vein .
What Is The Function Of The Superior Vena Cava?
As posit , the super venous blood vessel cava is located in the upper thorax region . As the location of the mineral vein would indicate , the social function of the superior vena cava is to behave blood from the face , neck , branch , and other upper consistence locations to the correct atrium of the heart .
What Is The Function Of The Inferior Vena Cava?
Since the deficient vena cava is located along the pricker and the back , it in itself suggests that the function of deficient vena cava is to contain deoxygenated stock from the lower extremity like the ramification , back , abdomen and pelvis to the substance .
