Flow of blood in the body

Flow of Blood in the Body By Evan Huang
The Flow of Carbon Dioxide Carbon dioxide rich blood flows through veins into the right atrium of the heart. Next, the carbon dioxide rich blood passes through the Tricuspid valve and into the right ventricle. Third, the carbon dioxide rich blood flows out of the heart into the lungs. Then, the carbon dioxide rich blood gets dropped off at capillaries which flows into tiny air sacs called alveoli in the lungs. Last air draws in oxygen and blowing out carbon dioxide.

The Flow of Oxygen Oxygen rich blood flows through arteries from the alveoli in the lungs into the left atrium. Second, the oxygen rich blood passes through the Mitral valve and into the left ventricle. Next, the oxygen rich blood flows through the largest artery in the body, the aorta. Last, the aorta splits into millions and millions of arteries that lead to capillaries which cells can pick up oxygen and get rid of carbon dioxide.
Capillaries
Capillaries are microscopic vessels in the body. Capillaries are where veins and arteries meet. Capillaries are like a shop, where oxygen is the goods and carbon dioxide is the money. Cells buy the “goods” and pay the “money.”
Veins
Veins are microscopic vessels in the body that carry carbon dioxide from capillaries to the heart and from the heart to the lungs.
Arteries
Arteries are microscopic vessels in the body that carry oxygen rich blood from the heart and lungs to cells.
Alveoli
Alveoli are tiny air sacs that store both carbon dioxide and oxygen.
