Question

Describe and explain how blood flows from the foot to the lungs?

Answer 1

Explanation:

pulmonary veins empty oxygen-rich blood from the lungs into the left atrium. As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve. ... As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.
