The left ventricle has a thicker muscular wall than the right ventricle in order to withstand the highest pressure generated.
True
False
The right ventricle pumps deoxygenated blood to the lungs for oxygenation.
True
False
There are four valves present in the human heart.
True
False
What is happening at point A?
The bicuspid valve opens for blood to flow from left atrium to left ventricle
The bicuspid valve opens for blood to flow from left ventricle to aorta
The bicuspid valve closes to prevent backflow of blood from left atrium to left ventricle
The bicuspid valve closes to prevent backflow of blood from left ventricle to left atrium
What is happening at point B?
Bicuspid valve is forced open
Bicuspid valve remains closed
Semi-lunar valve is forced open
Semi-lunar valve remains closed
When does ventricular systole occur?
From points A to B
From points A to C
From points B to C
From points B to D
What causes the changes in pressure in the ventricles?
Opening and closing of atrioventricular valves
Opening and closing of semi-lunar valves
Contraction and relaxation of muscles in ventricles
Contraction and relaxation of ventricles
One cardiac cycle is made up of
one atrial systole + one ventricular diastole
one atrial systole + one ventricular systole
one ventricular systole + one ventricular diastole
one ventricular systole + one atrial diastole
