The cardiac cycle

Question 1

What side pumps the deoxygenated blood?

Answer 1

right side, right atrium and right ventricule
pulmonary artery and vena

Question 2

What side pumps oxygenated blood?

Answer 2

left side, left atrium and left ventricule
pulmonary vein and aorta

Question 3

What are the semilunar valves?

Answer 3

valves found in the aorta and pulmonary artery which prevent backflow of blood into the ventricles

Question 4

What re the atrioventricular valves?

Answer 4

valves found between the atrium and ventricle

Question 5

What happens during the Atrial systole?

Answer 5

ventricles are relaxed and atria contract, this decreases their volume so increases the pressure which forces AV valves to open
blood is pushed into ventricles so pressure slightly increased

Question 6

What happens during Ventricular systole?

Answer 6

the atria relax, ventricules contract which decreases the volume and increases the pressure forcing AV valves to close
When pressure increases enough the SL valves are forced open and blood is pumped out through the arteries

Question 7

What happens during the diastole?

Answer 7

Both atria and ventricles relax, pressure in arteries is higher than the ventricles so the SL valves shut
Blood starts to enter the atria from the veins so this starts to increase the pressure of the atria eventually, pressure exceeds the ventricule pressure
AV Valves open slightly and blood begins to passively flow into the ventricles

Question 8

What is the equation for Cardiac output?

Answer 8

Stroke volume x heart rate
