Learn how the size of a person will also affect the amount of fluid carried in a blood vessel with information from a nurse and respiratory therapist in this free video on blood vessels.

Find out how lower and higher arterial pressure will affect blood flow with information from a nurse and respiratory therapist in this free video on blood vessels.
In the human body, there are about 60,000 miles of blood vessels through which the heart pumps blood. There are approximately 300 million capillaries in the human body.

The smallest blood vessels are the capillaries, which is where the exchange mechanism of oxygen and carbon dioxide takes place. Learn about the tiny wall space within capillaries that moves oxygen and nutrition to surrounding tissue with information from a nurse and respiratory therapist in this free video on blood vessels.
The blood vessels that carry oxygenated blood through the body are the arteries, which pump blood away from the heart. Identify oxygenated blood by its red color with help from a nurse and respiratory therapist in this free video on blood vessels.
The blood vessels that carry blood towards the heart are the veins, which carry blue, de-oxygenated blood. Learn how the veins carry blood to the heart for oxygenation with information from a nurse and respiratory therapist in this free video on blood vessels.
Blood vessels look blue because they are veins carrying de-oxygenated blood back to the heart. Blood is only red when it is combined with oxygen. Identify veins by their blue color with information from a nurse and respiratory therapist in this free video on blood vessels.
