The following are some of the blood vessels associated with the heart: Tricuspid valve: Prevents the backflow of blood as it is pumped from the right atrium to the right ventricle.īlood vessels are intricate networks of hollow tubes that transport blood throughout the entire body.Pulmonary valve: Prevents the backflow of blood as it is pumped from the right ventricle to the pulmonary artery.Mitral valve: Prevents the backflow of blood as it is pumped from the left atrium to the left ventricle.Aortic valve: Prevents the backflow of blood as it is pumped from the left ventricle to the aorta.Heart valves are flap-like structures that allow blood to flow in one direction. Systole phase: The ventricles contract and pump blood to the arteries.Diastole phase: The heart ventricles are relaxed and the heart fills with blood.Below are the two phases of the cardiac cycle: The Cardiac cycle is the sequence of events that occurs when the heart beats. Sinoatrial Node: A section of nodal tissue that sets the rate of contraction for the heart.
