Topic: Body Transport System Subtopic: The movement of blood through the heart
What happens when blood enters ventricles?
Answer: When the blood enters the ventricles, more blood enters the atria, ventricles contract making the valves between the chambers close to prevent backward flow of blood into the atria. The blood is then pumped out of the semi-lunar valves located between the arteries and ventricles.
