The inferior vena cava (or IVC) is a large vein that carries de-oxygenated blood from the lower half of the body into the heart. The vein connects to the heart at a valve attached to the right atrium. In the other direction the vein travels retroperitoneally along the posterior wall of the abdominal cavity, anterior to the vertebrae and to the right of the abdominal aorta until it branches into the iliac veins which receive blood from the legs. In geology, a vein is a regularly shaped and lengthy occurrence of an ore; a lode. ... Red blood cells (erythrocytes) are present in the blood and help carry oxygen to the rest of the cells in the body Blood is a circulating tissue composed of fluid plasma and cells (red blood cells, white blood cells, platelets). ... The heart and lungs (from an older edition of Grays Anatomy) The heart (Latin cor) is a hollow, muscular organ that pumps blood through the blood vessels by repeated, rhythmic contractions. ... This page is about the muscular organ, the Heart. ... A diagram of a thoracic vertebra. ... AORTA can also mean always-on real-time access, referring to WAN computer networks. ...
There are exceptions to this in anastomoses between the two. Two good examples are the azygos vein system and in the venous plexuses next to the spinal cord but the preceding statement is largely true. The azygos vein is so named because it is unpaired, having no matching vein on the left side of the body. ... The spinal cord is a part of the vertebrate nervous system that is enclosed in and protected by the vertebral column (it passes through the spinal canal). ...
Health problems attributed to the IVC are typically associated to something pressing against it, and not to ruptures. Two common sources or pressure are the aorta, and, a fetus within a pregnant woman. AORTA can also mean always-on real-time access, referring to WAN computer networks. ... Fetus at eight weeks A fetus (alternatively foetus or fœtus) is an embryo in later stages of development, from the third month of pregnancy until birth in humans. ...
The vein that carries de-oxyginated blood from the upper half of the body is the superior vena cava. The superior vena cava (also known as the anterior vena cava) is a large but short vein that carries de-oxygenated blood from the upper half of the body into the heart. ...
The inferiorvenacava, larger than the superior, returns the blood from the lower half of the body, and opens into the lowest part of the atrium, near the atrial septum, its orifice being directed upward and backward, and guarded by a rudimentary valve, the valve of the inferiorvenacava (Eustachian valve).
The blood entering the atrium through the superior venacava is directed downward and forward, i.e., toward the atrioventricular orifice, while that entering through the inferiorvenacava is directed upward and backward, toward the atrial septum.
The valve of the inferiorvenacava (valvula venœ cavœ inferioris [Eustachii]; Eustachian valve) is situated in front of the orifice of the inferiorvenacava.
