The Aorta and Its Branches

The aorta is the largest artery in the body and is divided into 3 parts: the ascending aorta, arch of the aorta, and descending aorta.

Thumbnail
Ascending Aorta

The ascending aorta is the first portion of the aorta; it includes the aortic sinuses, the bulb of the aorta, and the sinotubular junction.

Thumbnail
Arch of the Aorta

The arch of the aorta follows the ascending aorta and begins at the level of the second sternocostal articulation of the right side.

Thumbnail
Thoracic Aorta

The thoracic aorta is the section of the aorta that travels through the thoracic cavity to carry blood to the head, neck, thorax and arms.

Thumbnail
Abdominal Aorta

The abdominal aorta is the largest artery in the abdominal cavity and supplies blood to most of the abdominal organs.

Thumbnail
Arteries of the Pelvis and Lower Limbs

The abdominal aorta divides into the major arteries of the leg: the femoral, popliteal, tibial, dorsal foot, plantar, and fibular arteries.

Thumbnail
Principal Veins

Veins are blood vessels that carry blood towards the heart, have thin, inelastic walls, and contain numerous valves.

Thumbnail
Veins of the Head and Neck

In the head and neck, blood circulates from the upper systemic loop, which originates at the aortic arch.

Thumbnail
Veins of the Upper Limbs

The veins of the upper extremity are divided into superficial and deep veins, indicating their relative depths from the skin.

Thumbnail
Veins of the Thorax

The veins of the thorax drain deoxygenated blood from the thorax region for return to the heart.

Thumbnail
Veins of the Abdomen and Pelvis

The major veins of the abdomen and pelvis return deoxygenated blood from the abdomen and pelvis to the heart.

Thumbnail
Veins of the Lower Limbs

The deep veins of the lower extremity have valves for unidirectional flow and accompany the arteries and their branches.
