Answers:
1!. Vena cava --> right atrium --> right ventricle --> lungs --> left atrium --> left ventricle --> aorta
2!. When blood is traveling back to the heart (in the veins), it has to have help from surrounding tissues and muscles!. Pumping muscles help push blood back toward the heart!. Valves are important to prevent backflow and keep the blood moving in the right direction!.Www@Answer-Health@Com
