Hemoglobin
|
Millions of molecules which are called hemoglobin are found in red blood cells. Oxygen and carbon dioxide bind to them.

Pulmonary Vein
|
These are the veins that carry blood that is rich in oxygen from the lungs to the left atrium.
|
|
|
Pulmonary Artery
|
The blood vessels that carry blood that is low in oxygen from the right ventricle to the lungs.
|
|
|
Varicose Vein
|
These have valves that do not work properly, allowing blood to flow backward, creating swollen veins. They are common on legs and look like raised, bluish blood vessels.
|
|
