Veins are vessels of the circulatory system that support circulation by conveying blood to the heart.
Blood flowing through the circulatory system transports nutrients, oxygen, and water to cells throughout the body.
● Deep veins are located within muscle tissue. They have a corresponding artery nearby.
● Superficial veins are closer to the skin’s surface. They don’t have corresponding arteries.
● Pulmonary veins transport blood that’s been filled with oxygen by the lungs to the heart. Each lung has two sets of pulmonary veins, a right and left one.
● Systemic veins are located throughout the body from the legs up to the neck, including the arms and trunk. They transport deoxygenated blood back to the heart.
