• a. It prevents the backflow of the blood from the right ventricle back to the right atrium.

• b. It prevents the backflow of the blood from the pulmonary artery back to the right ventricle.

• c. It prevents the backflow of the blood from the left ventricle back artery to the left atrium.

• d. It prevents the backflow of the blood from the aorta back artery to the left ventricle.

The difference between auricles and ventricles.

• Auricles receive blood; ventricles pump blood.
• Ventricles are responsible for oxygen exchange.
• Auricles are larger than ventricles.
• Auricles pump blood; ventricles receive blood.

What separates the two auricles?

• Interventricular septum
• Interatrial septum
• Coronary sinus
• Pulmonary vein

What separates the two ventricles?

• Coronary sinus
• Atrioventricular valve
• Pulmonary artery
• Interventricular septum

The auricle is separated from the ventricle by?

• Cardiac sk

• Coronary artery
• Semilunar valve
• Pulmonary vein

This enables the blood to move from the auricles to the ventricles.

• Cardiac Valves

• Aorta
• Pulmonary arteries
• Semilunar valves
