FMA47201 3D mesh
Superior vena cava
The large venous trunk in the superior mediastinum that returns deoxygenated blood from the head, neck, upper limbs, and thorax into the right atrium.
Veins return blood toward the heart. Superficial and deep networks collect blood from the tissues; the pulmonary veins bring oxygenated blood back from the lungs.
The BodyParts3D reference dataset models 404 venous pieces across 225 FMA concepts, encompassing caval tributaries, cardiac veins, the hepatic portal tree, cranial venous sinuses, and limb veins.
Collects blood from systemic capillary beds through superficial and deep venous networks and returns it toward the right atrium.
Drains nutrient-rich blood from the digestive tract and spleen through the hepatic portal vein to the liver for processing.
Returns freshly oxygenated blood from the lungs to the left atrium via the pulmonary veins.

The large venous trunk in the superior mediastinum that returns deoxygenated blood from the head, neck, upper limbs, and thorax into the right atrium.
The primary venous channel on the posterior surface of the heart that collects blood from the myocardium and empties into the right atrium.
A major venous trunk (modeled across 18 segments in the atlas) that conveys blood from the gastrointestinal tract, pancreas, and spleen to the liver.
A longitudinal venous trunk ascending along the posterior thoracic wall that drains the thoracic wall and upper lumbar region into the superior vena cava.
A major tributary of the hepatic portal system draining blood from the spleen, parts of the stomach, and the pancreas.
The venous trunk draining filtered blood from the left kidney into the inferior vena cava.
Every anatomical structure assigned to the Veins layer in atlas.json. Curated landmarks include a Learn more guide, and all 225 structures can be selected directly in the 3D viewer.
Launch the 3D viewer with the Veins activated. Orbit the camera, use the Exploded View slider to separate overlapping pieces, and click individual structures to inspect their FMA reference ID and anatomical metadata.
You have not selected any structures in the Veins inside the 3D viewer yet during this session. Click Explore in 3D or any structure card above to inspect a structure on the 3D model.
Veins return blood toward the heart from throughout the body.
Superficial and deep venous networks collect blood from systemic tissues.
Pulmonary veins bring oxygenated blood back from the lungs to the left side of the heart.
The hepatic portal vein (FMA50735) routes venous blood from digestive organs to the liver.
Systemic veins empty into the right atrium, while pulmonary veins return oxygenated blood from the lungs to the left atrium.
The hepatic portal venous network carries absorbed nutrients from the digestive organs directly to the liver for metabolic processing.
Lymphatic vessels return excess interstitial fluid collected from tissues back into the venous circulation.
