Veins return blood to the heart from all the organs of the body. Arteries carry blood with oxygen and nutrients away from the heart to the rest of the body. The large veins parallel the large arteries and often share the same name. In addition, many unnamed small veins form irregular networks and connect with the large veins.

2025年1月9日 · Explore the intricate human venous system, detailing its structure, function, and the vital role veins play in circulatory health. The human venous system is essential for circulating blood back to the heart, ensuring oxygen-depleted blood is returned for reoxygenation.

The venous system is the system of veins in the systemic and pulmonary circulations that return blood to the heart. In the systemic circulation the return is of deoxygenated blood from the organs and tissues of the body, and in the pulmonary circulation the pulmonary veins return oxygenated blood from the lungs to the heart.

Veins are flexible, hollow tubes that are part of the circulatory system that moves blood through your body. Veins bring oxygen-poor blood back to your heart, which pumps your blood. Arteries carry oxygen-rich blood away from your heart.

What is the vascular system? The vascular system is made up of the vessels that carry blood and lymph fluid through the body. It's also called the circulatory system.
