Question

Describe the flow of blood through the heart of human being.​

Answer 1

Answer:

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve

Answer 2

Explanation:

Veins are thin-walled and have valves that prevent the blood from flowing back in the wrong direction. Veins carry blood heading toward the heart. Blood coming from the tissues has delivered O2 and picked up CO2 from the cells.
