Questions & Step-by-Step Solutions

What is the role of the aortic valve?
  • Step 1: Understand that the heart has four chambers: two atria and two ventricles.
  • Step 2: Know that the left ventricle is one of the heart's chambers that pumps blood out to the body.
  • Step 3: Learn that the aortic valve is located between the left ventricle and the aorta, which is the main artery that carries blood to the body.
  • Step 4: Realize that when the left ventricle contracts, it pushes blood into the aorta through the aortic valve.
  • Step 5: Understand that the aortic valve opens to allow blood to flow out and then closes to prevent blood from flowing back into the left ventricle.
