A large artery stemming from the left ventricle of the heart through which blood travels on its way to the body.
The largest artery in the body that delivers oxygenated blood from the left ventricle to the entire body.
The largest artery in the body, which carries oxygenated blood pumped from the left muscular chamber of the heart, extends through the chest and abdomen, and branches into arteries supplying blood to the entire body.
The body’s main artery originating from the left ventricle of the heart, extending upward then downward to the pelvis, and which carries oxygenated blood to its branches and hence to the body tissues.
The main artery in the body, which sends blood containing oxygen from the heart to other blood vessels around the body.
Congenital narrowing of the aorta, which results in high blood pressure in the upper part of the body and low blood pressure in the lower part.
The vessel that carries blood from the left ventricle of the heart to the vessels that serve the rest of the body.
Main trunk of the arterial blood circulatory system from which all other arteries (except the pulmonary) branch. This large artery stems from the heart at the left ventricle, passes upward (ascending aorta) toward the neck, arches (aortic arch) and loops, and descends down¬ ward (descending aorta) along the left side of the vertebral column through the chest region (thoracic aorta), through the diaphragm to the abdomen (abdominal aorta), where it divides into two iliac arteries. Major arteries (e.g., carotid, coronary) branch from the aorta, transporting the aorta’s freshly oxygenated blood to the various organs of the body. The aortic value, situated between the left ventricle and the aorta, prevents blood from flowing back from the aorta into the heart.
The largest artery in the body. All other arteries branch out from the aorta to carry oxygen-rich blood from the heart to the rest of the body tissues. The aorta, which is about an inch wide, begins in the left ventricle, one of the four chambers of the heart. When the heart beats, the aortic valve opens to allow oxygen-rich blood to flow from the ventricle into the aorta.
The largest artery in the body. All other arteries branch out from the aorta to carry oxygen-rich blood from the heart to the rest of the body tissues. The aorta, which is about an inch wide, begins in the lower left chamber, or left ventricle, of the heart. When the heart beats, the aortic valve opens to allow oxygen-rich blood to flow from the ventricle into the aorta. When the beat ends, the valve closes to prevent blood from flowing back into the ventricle. Arteries branching off the aorta carry blood into the upper body, arms, neck, and head. In the lower abdomen the descending aorta divides into two smaller arteries, which supply blood to the legs and the organs in the abdomen, including the stomach, kidneys, intestines, spleen, and reproductive organs.
The main artery of the body, from which all others derive. It arises from the left ventricle (ascending aorta), arches over the top of the heart and descends in front of the backbone (descending aorta), giving off large and small branches and finally dividing near the pelvis to form the right and left iliac arteries. The part of the descending aorta from the aortic arch lo the diaphragm is called the thoracic aorta; the part below the diaphragm is the abdominal aorta.
The large vessel which opens out of the left ventricle of the HEART and carries blood to all of the body. It is about 45 cm (1½ feet) long and 2-5 cm (1 inch) wide. It passes first to the right, and lies nearest the surface behind the end of the second right rib-cartilage; then it curves backwards and to the left, passes down behind the left lung close to the backbone, and through an opening in the diaphragm into the abdomen. There it divides, at the level of the navel, into the two common iliac arteries, which carry blood to the lower limbs.
The main trunk of the arterial system of the body.
The largest artery in the body, through which blood leaves the left ventricle.
The major trunk of the system of arteries that carries blood away from the heart to the tissues.
In the intricate network of human anatomy, the largest blood vessel, known as the artery, takes center stage. It assumes the crucial responsibility of transporting blood from the left ventricle, a chamber of the heart, to every nook and cranny of the body, ensuring a continuous circulation.
The aorta, the main artery of the body, serves the vital function of supplying oxygenated blood to all other body parts. Originating from the left ventricle, the primary pumping chamber of the heart, it forms an arch over the heart before descending behind it through the chest cavity. Ultimately, it terminates in the abdomen, where it branches into the two common iliac arteries, supplying the legs. The aorta boasts a robust and thick-walled structure, equipped with a large diameter to accommodate the high pressure and significant volume of blood coursing through it.
The aorta, along with other arteries, can experience narrowing due to a condition called atherosclerosis, characterized by the accumulation of fat deposits on its walls. This narrowing can lead to hypertension or high blood pressure. There are specific disorders that affect the aorta, such as coarctation of the aorta, which is a congenital condition where the aorta is unusually narrow from birth, and aortitis, which refers to the inflammation of the aortic wall. Both aortitis and atherosclerosis can increase the risk of developing an aortic aneurysm, which is the abnormal ballooning of the aortic wall. In some cases, surgical intervention may be necessary to address the aortic aneurysm.
