Question

how heart is working?​

Answer 1

$\huge{\underline{\underline{\mathfrak{Answer}}}}$

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.

Answer 2

Answer:

The human heart works like a pump sending blood around your body to keep you alive. ... This blood delivers oxygen and nutrients to all parts of your body, and carries away unwanted carbon dioxide and waste products.

Your heart and circulatory system works together to deliver blood to your organs so they can function.
