Ascending aorta
The initial segment of the aorta arising from the left ventricle, giving off the coronary arteries before continuing as the aortic arch.
The heart drives blood through the circulation. Arteries carry blood away from the heart to supply tissues or, in the pulmonary circuit, to the lungs.
With 639 modeled pieces across 423 FMA concepts, the arterial layer is the most granular system in the BodyParts3D web atlas, tracing major trunks (aorta, pulmonary trunk, celiac trunk) down to regional cerebral, thoracic, abdominal, and limb branches.
Carries blood away from the heart under high pressure generated by ventricular contraction.
Distributes oxygenated blood from the left ventricle via the aorta and its branches to supply all systemic tissues and organs.
Carries deoxygenated blood from the right ventricle via the pulmonary trunk and pulmonary arteries to the lungs for gas exchange.

The initial segment of the aorta arising from the left ventricle, giving off the coronary arteries before continuing as the aortic arch.
The curved segment of the thoracic aorta in the superior mediastinum that gives rise to the major arterial trunks supplying the head, neck, and upper limbs.
The continuation of the descending aorta below the diaphragm, supplying the abdominal viscera, retroperitoneal organs, and bifurcating into the common iliac arteries.
The major arterial vessel arising from the right ventricle that divides into the left and right pulmonary arteries to carry blood to the lungs.
The first major anterior branch of the abdominal aorta, supplying oxygenated blood to the stomach, liver, spleen, pancreas, and proximal duodenum.
A major intracranial artery formed by the union of the vertebral arteries along the ventral surface of the pons, supplying the brainstem, cerebellum, and posterior cerebrum.

By anatomical definition, arteries carry blood away from the heart.
Systemic arteries distribute oxygenated blood to body tissues, while pulmonary arteries carry blood to the lungs.
The arterial system contains 639 modeled 3D pieces in this atlas—the highest piece count of all 15 systems.
The heart provides the muscular pumping force that drives blood into the pulmonary trunk and ascending aorta.
After arterial blood perfuses capillary beds in tissues, the venous system collects and returns the blood back toward the heart.
In the pulmonary circuit, arteries carry blood from the right side of the heart to the lungs where oxygen is replenished.
