What else can I help you with?
Why do you have veins that have oxygen in them?
The only veins that have oxygen in them are the pulmonary veins. The definition of a vein is a blood vessel that carries blood to the heart. This blood is usually de-oxygenated, but the pulmonary veins are the exception.
Which vessels transport blood toward the heart?
Veins usually transport blood towards the heart.
Which blood vessels that usually return blood to the heart?
veins
How are artiries and veins alike?
They both carry blood in them, but veins take blood to the heart, artiries take blood from the heart, usually!
Do veins carry oxygenated blood away from the heart?
Veins carry blood to the heart. They usually carry oxygen-poor blood.
Which type of blood vessel usually carries oxygen-poor blood?
Veins are the blood vessels that usually carry oxygen-poor blood. The exception is the pulmonary vein, which carries oxygenated blood.
What percentage of blood is stored in the veins?
Approximately 60-70% of the body's blood volume is stored in the veins at any given time. This is because veins function as capacitance vessels, able to hold a larger proportion of blood compared to arteries which have a smaller storage capacity.
What is one of the smallest blood vessels which connect the arteries and the veins is a?
The capillaries are the smallest blood vessels and are usually found between arteries and veins.
What usually carries blood away from the heart?
veinsAnswerArteries are the blood vessels that carry blood away from the heart, not veins. Veins are the blood vessels that carry blood towards the heart. The only exceptions being the pulmonary and umbilical veins, both of which carry oxygenated blood.
What are the blood vessels that Carry?
The pulmonary arteries, which carry blood from the heart to the lungs, are the only arteries which carry deoxygenated blood. Conversely, the pulmonary veins, carrying blood from the lungs to the left atrium of the heart, are the only veins carrying oxygenated blood. Usually veins carry deoxygenated blood.
What kind of blood does vein carry?
Usually veins carry blood low in oxygen back to the heart except for the pulmonary veins. They carry blood higher in oxygen.
Carries blood to the heart?
Veins carry blood to the heart from the body, and arteries carry blood from the heart. Usually, the blood in veins is deoxygenated (ie. has very little oxygen left), and arteries have oxygenated blood. However, in the pulmonary ("lungs") circulatory system, it is the opposite (ie. veins ALWAYS carry blood TO the heart, whether oxygenated or not, and vice versa).
