blood flow through the heart and around the body

• though what does deoxygenated blood return to the heart


  the vena cava
• after the blood enters through the vena cava where does it enter


  into the right atrium
• what happens when the deoxygenated blood is in the right atrium


  the right atrium contracts and the blood moves into the right ventricle through the tricuspid valve
• what happens when the deoxygenated blood enters the right ventricle


  it contracts and closes the tricuspid valves and forces blood through the pulmonary artery via the semi lunar valve
• where does the blood go once in the pulmonary artery


  it will be transported to the lungs to become oxygenated
• where does the blood go once it is oxygenated in the lungs


  it will pass though the pulmonary vein to get back to the heart
• where will the pulmonary vein take the blood


  to the left atrium
• when the left atrium contracts and pushes the blood into the left ventricle what valve will it pass through

  bicuspid valve
• what will happen once the blood is in the left ventricle


  it will contract forcing the blood through the semi lunar valve and to the aorta where it will be pumped around the rest of the body
