1.Aorta(LARGEST ARTERY)
Diameter: 350mm
Blood flow: 4900 milliliters per minute.
Common problem: Aortic Stenosis Location: Center of the thorax..
The aorta is the largest artery in the human body, as well as the main artery in the circulatory system. In fact, it’s nearly as big around as a garden hose and about a foot long. The aorta descends from the left ventricle of the heart down the center of the body, supplying most other major blood vessels in the circulatory system. Once the aorta reaches the boundary of the diaphragm, it is then referred to as the abdominal aorta. The abdominal aorta ends where it connects with the paired iliac arteries, which lead through the pelvic area to the common femoral arteries.
2.Inferior Vena Cava(LARGEST VEIN)
The largest vein in the human body is the inferior vena cava, which carries deoxygenated blood from the lower half of the body back up to the heart. Ultrasound imaging studies have found that the inferior vena cava varies considerably in size from one individual to another, with diameters ranging from 1.2 cm to 3 cm (0.47–1.18 in). The average inferior vena cava diameter for an adult is around 2 cm (0.78 in).
