MCQ 1 DURING The Isovolumetric Relaxation Phase of the Pressure Volume Loop
(a) The intraventricular pressure drops by about 20mmHg
(b) The intraventricular pressure remains constant
(c) Occurs during passive ventricular filling
(d) Occurs in diastole
(e) Ends when the atrioventricular valves open
(b) The intraventricular pressure remains constant
(c) Occurs during passive ventricular filling
(d) Occurs in diastole
(e) Ends when the atrioventricular valves open
Answer
|
E
Isovolumetric relaxation, involves the closing of the aortic and pulmonary valves. The pressure decreases markedly, until the atrioventricular valves open and passive filling commences. |

(b) The end-diastolic ventricular volume is 190mL
(c) Isovolumetric relaxation occurs following closure of the atrioventricular valves
(d) Right ventricular contraction occurs before left
(e) During isovolumetric contraction atrial pressure rises
(b) The end-diastolic ventricular volume is 190mL
(c) Isovolumetric relaxation occurs following closure of the atrioventricular valves
(d) Right ventricular contraction occurs before left
(e) During isovolumetric contraction atrial pressure rises
ANSWER
E
