What did William Harvey invent?
He discovered the circulation system of the body
What organ is considered primarily a part of the circulatory system?
The heart is a probably the most important organ/part of the circulatory system. It is the muscle that pumps your blood through various parts of your body. As oxygen-rich blood goes through your body, it slowly loses its oxygen, and returns using veins like a highway to get back to your heart and lungs
What is the main job of blood?
Blood carries oxygen from the lungs to your heart, where the heart pumps it throughout the body. Your blood is red because the red blood cells have hemoglobin that gives it the red color. If there is no oxygen, your blood will turn blue, which has carbon dioxide. Blood is needed to allow your cells to swim throughout the body. For example, white blood cells need to swim fast to reach and attack the virus.
