What is the mitral valve?
Which vessels carry oxygenated blood from the lungs to the heart?
What are the pulmonary veins?
During atrial systole, what happens?
What is the atria contract and push blood into the ventricles?
Which valves close to produce S1?
What are the tricuspid and mitral valves?
Which chamber receives oxygenated blood from the lungs?
What is the left atrium?
Which valve is located between the left ventricle and aorta?
What is the aortic valve?
Which chamber receives blood from the pulmonary veins?
What is the left atrium?
During ventricular systole, which valves open to allow blood to leave the ventricles?
What are the pulmonary and aortic valves?
Which valves close to produce S2?
What are the pulmonary and aortic valves?
Which chamber pumps oxygenated blood to the entire body?
What is the left ventricle?
What are the two atrioventricular valves?
What are the tricuspid and mitral valves?
What part of the aorta curves and gives rise to arteries supplying the head and arms?
What is the aortic arch?
What causes the AV valves to close during ventricular systole?
Increased pressure inside the ventricles.
Explain the difference between S1 and S2.
What is S1 is caused by closure of the AV valves; S2 is caused by closure of the semilunar valves.
