Question

If you help I'll give you a brain list

and for the record The question wants me to explain how the blood in the heart reaches the lungs

It's everything in the photo; all you have to do now is explain it.

Answer 1

Blood leaves the heart through the pulmonic valve, it then moves through the pulmonary arteries which branches to the left and right lungs.

When the deoxygenated blood reaches the lungs, it is then oxygenated and returns to the heart through our pulmonary veins.

Hope this better explains it!
