What does the superior mesenteric artery supply?
The superior mesenteric artery provides oxygenated blood and nutrients to the intestines. These organs are part of the digestive system. The artery branches off of the aorta, which is the body’s largest blood vessel. Superior refers to the artery’s location above other arteries that supply the intestines.

Article first time published onWhat does the internal thoracic artery supply?
The internal thoracic artery functions to supply the anterior chest wall, from the clavicle to the umbilicus. This area of supply also includes supply to the sternum and breasts.
What are mediastinal arteries?
Small branches of the thoracic aorta that supply nerves, pleura, lymph nodes and other tissue in the posterior mediastinum.

Which blood vessels give rise to the femoral artery?
The common femoral artery forms as a continuation of the external iliac artery below the level of the inguinal ligament. It is found just medial to the midpoint of the inguinal ligament in the inguinal crease region.
What artery supplies the right lateral wall of the heart?
The marginal branch of the right coronary artery provides blood supply to the lateral portion of the right ventricle. The posterior descending artery branch supplies blood to the inferior aspect of the heart.
What are mesenteric arteries?
The mesenteric arteries take blood from the aorta and distribute it to a large portion of the gastrointestinal tract. Both the superior and inferior mesenteric arteries arise from the abdominal aorta. Each of these arteries travel through the mesentery, within which they branch several times before reaching the gut.
What artery supplies the large intestine?
The blood supply to the large intestine originates in the superior and inferior mesenteric arteries.
What does the celiac artery supply?
The celiac artery supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen, and the superior half of both the duodenum and the pancreas. These structures correspond to the embryonic foregut.
What do lumbar arteries supply?
cardiovascular system. The lumbar arteries are arranged in four pairs and supply the muscles of the abdominal wall, the skin, the lumbar vertebrae, the spinal cord, and the meninges (spinal-cord coverings).
What artery supplies the diaphragm?
The blood supply to the diaphragm is from the superior phrenic, musculophrenic, inferior phrenic, pericardiacophrenic, and lower internal intercostal arteries.
What is the most common origin of the inferior phrenic arteries?
The inferior phrenic arteries usually originate from the aorta or celiac artery, and less frequently from the renal, hepatic or left gastric arteries.
What two veins merge to form the superior vena cava?
On each side, the subclavian vein, the principal vein of the upper extremity, joins with the internal jugular, the principal vein of the head and neck, here, behind the medial end of the clavicle, forming the brachiocephalic vein. The two brachiocephalic veins enter the thorax and unite, forming the superior vena cava.
What does the thoracic aorta supply?
The thoracic aorta runs from the aortic arch to the diaphragm, which is the point of separation between the chest cavity and the abdominal cavity. It provides blood to the muscles of the chest wall and the spinal cord.
Which veins lead directly back to superior and inferior vena cava?
The superior vena cava is formed by the left and right brachiocephalic veins, which receive blood from the upper limbs, head and neck. The inferior vena cava returns blood from the abdomen and lower limbs. The hepatic veins of the liver and renal veins of the kidney drain directly into the inferior vena cava.
Where does the inferior mesenteric artery supply blood to?
Vascular supply The inferior mesenteric artery, also a branch of the abdominal aorta, supplies the distal third of the transverse colon, the descending colon and sigmoid colon, and the superior portion of the rectum as the superior hemorrhoidal artery.
Where does inferior suprarenal arteries come from?
