Deoxygenated blood
There are three different types of blood vessels: arteries (which carry blood away from the heart) veins (which carry blood toward the heart) and capillaries (which carry blood from arteries to veins). So veins are a type of vessel, but not the only type.
There are three major types of blood vessels in the body, the arteries, capillaries and veins. The vessels that carry blood towards the heart are the veins.
Arteries carry blood away from the heart. Veins carry blood to the heart.
They are called veins. Arteries carry blood from the heart. Veins carry blood to the heart.
Veins are the blood vessels that usually carry oxygen-poor blood. The exception is the pulmonary vein, which carries oxygenated blood.
Veins carry blood to the heart. They usually carry oxygen-poor blood.
Veins are blood vessels that carry blood toward the heart.
In all cases except one, veins carry deoxygenated blood. The exception is the pulmonary veins which carry oxygenated blood to the heart from the lungs. Veins ALWAYS carry blood to the heart.
Veins carry stale, or deoxygenated blood from the body back to the heart. The exception to this rule is the pulmonary veins, which carry oxygenated blood from the lungs to the heart.
Cardiac veins carry blood from ? to ?
Veins carry oxygen depleted blood to the heart.
Red veins carry oxygenated blood.
