Detailed explanation-2: -A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart. The heart valves, which keep blood flowing in the right direction, are gates at the chamber openings.
Detailed explanation-3: -Which statement most accurately describes the human heart? It has two atria and one ventricle, and it pumps blood directly into veins.
