The three basic types of blood vessels, including capillaries, arteries and veins.
• Arteries take oxygen-rich blood away from heart.
• Veins take blood back toward heart.
• Capillaries are very tiny blood vessels that form a connection between arteries and veins. Transfer of nutrients, oxygen and wastes in and out of body facilitated by the capillary.
3. The Blood
The heart pumps blood throughout body. The blood is a substance that carries water, nutrients, waste products and oxygen to and from body cells. A young person will have up to a gallon of blood, whereas an adult will have about 5 quarts of blood. It is important to note that blood looks like an ordinary red liquid, but it's in fact made up of solids, liquids and small amounts of carbon dioxide and oxygen. Different blood cells include red blood cells, white blood cells, plasma and platelets.
4. The Lungs
Lungs aren't technically a part of circulatory system organs, but they really help make it possible for heart to function correctly. Lungs provide oxygen for body. The lungs send oxygen-rich blood to the left side of heart and heart then uses blood vessels and arteries to transfer it to the rest of

    The respiratory system is responsible for taking in oxygen and releasing carbon dioxide. The lungs are the main organs in the respiratory system. According to the American Lung Association, red blood cells collect the oxygen from the lungs and carry it throughout the body where it is needed. As the red blood cells travel through the body, they collect the carbon dioxide, taking it back to the lungs where it is then exhaled.…
