The aorta is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries. The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
In human anatomy, the subclavian arteries are paired major arteries of the upper thorax, below the clavicle. They receive blood from the aortic arch. The left subclavian artery supplies blood to the left arm and the right subclavian artery supplies blood to the right arm, with some branches supplying the head and thorax. On the left side of the body, the subclavian comes directly off the aortic arch, while on the right side it arises from the relatively short brachiocephalic artery when it bifurcates into the subclavian and the right common carotid artery.
In human anatomy, the abdominal aorta is the largest artery in the abdominal cavity. As part of the aorta, it is a direct continuation of the descending aorta.
The renal arteries are paired arteries that supply the kidneys with blood. Each is directed across the crus of the diaphragm, so as to form nearly a right angle.
The celiacartery, also known as the celiac trunk or truncus coeliacus, is the first major branch of the abdominal aorta. It is about 1.25 cm in length. Branching from the aorta at thoracic vertebra 12 (T12) in humans, it is one of three anterior/ midline branches of the abdominal aorta.
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
In human anatomy, the bronchial arteries supply the lungs with oxygenated blood, and nutrition. Although there is much variation, there are usually two bronchial arteries that run to the left lung, and one to the right lung, and are a vital part of the respiratory system.
The facial artery is a branch of the external carotid artery that supplies structures of the superficial face.
In human anatomy, the superior epigastric artery is a terminal branch of the internal thoracic artery that provides arterial supply to the abdominal wall, and upper rectus abdominis muscle. It enters the rectus sheath to descend upon the inner surface of the rectus abdominis muscle. It ends by anastomosing with the inferior epigastric artery.
The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output.
The lingual artery arises from the external carotid artery between the superior thyroid artery and facial artery. It can be located easily in the tongue.
The thyrocervical trunk is a short artery of the neck. It arises from the subclavian artery, then promptly divides into its branches: the inferior thyroid artery, suprascapular artery, and (sometimes) the transverse cervical artery.
The suprarenal veins are two in number:
The inferior phrenic artery is a bilaterally paired artery of the abdominal cavity which represents the main source of arterial supply to the diaphragm. Each artery usually arises either from the coeliac trunk or the abdominal aorta, however, their origin is highly variable and the different sites of origin are different for the left artery and right artery. The superior suprarenal artery is a branch of the inferior phrenic artery.
The inferior thyroid artery is an artery in the neck. It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle. It then turns medially behind the carotid sheath and its contents, and also behind the sympathetic trunk, the middle cervical ganglion resting upon the vessel.
The middle suprarenal artery is a paired artery in the abdomen. It is a branch of the aorta. It supplies the adrenal gland.
The ovarian artery is an artery that supplies oxygenated blood to the ovary in females. It arises from the abdominal aorta below the renal artery. It can be found within the suspensory ligament of the ovary, anterior to the ovarian vein and ureter.
The inferior suprarenal artery is a paired artery that supplies the adrenal gland. It usually originates at the trunk of the renal artery before its terminal division, but with many common variations. It supplies the adrenal gland parenchyma, the ureter, and the surrounding cellular tissue and muscles.
The adrenal arteries are arteries in the human abdomen that supply blood to the adrenal glands.
