The 'Lub' sound of the heart is caused by .....
Atrioventricular valves closing
Semilunar valves closing
Blood flowing through the Pulmonary artery and aorta
Blood Flowing down into the ventricles
Which of the following is true about the semi-lunar valves in the heart?
They are between atria and ventricles
They close when pressure in the arteries is higher than pressure in the atria
They prevent backflow of blood into the atria
They open when pressure in the ventricles is higher than pressure in the arteries
During ventricular systole, which of the following occurs?
Atrioventricular valves close and semilunar valves close
Atrioventricular valves close and semilunar valves open
Atrioventricular valves open and semilunar valves are open
Atrioventricular valves open and semilunar valves close
Define diastole
when the heart is relaxing
when the heart is contracting
