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.
