The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart.It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.
It is a network of veins that sit in a cavity. It sits on both sides of the sphenoidal bone and pituitary gland , approximately 1 × 2 cm in size in an adult. [ 2 ] The carotid siphon of the internal carotid artery , and cranial nerves III, IV, V (branches V 1 and V 2 ) and VI all pass through this blood filled space.
The walls of the dural venous sinuses are composed of dura mater lined with endothelium, a specialized layer of flattened cells found in blood and lymph vessels.They differ from other blood vessels in that they lack a full set of vessel layers (e.g. tunica media) characteristic of arteries and veins.
It is a large-diameter (24 mm) short length vein that receives venous return from the upper half of the body, above the diaphragm. Venous return from the lower half, below the diaphragm, flows through the inferior vena cava. The SVC is located in the anterior right superior mediastinum. [1]
The azygos vein transports deoxygenated blood from the posterior walls of the thorax and abdomen into the superior vena cava.. It is formed by the union of the ascending lumbar veins with the right subcostal veins at the level of the 12th thoracic vertebra, ascending to the right of the descending aorta and thoracic duct, passing behind the right crus of diaphragm, anterior to the vertebral ...
Oxygen-poor blood enters the right side of the heart through two large veins. Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs.
