How does circulatory system works
Answers
Answer:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Answer:
The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
The now oxygen-rich blood, returns from the lungs and enters the left atrium. The oxygen-rich blood then flows from the left atrium to the left ventricle. The blood is then pumped through the main artery that supplies blood to the body, called the aorta, to supply tissues throughout your body with oxygen.
