MCDB ANATOMY (CELL BIOLOGY). COMPLETE2024/2025 QUESTIONS AND ANSWERS.
1 . Starting at the ejection phase, put the following steps of the
cardiac cycle in order from first to last. - Isovolumetric
relaxation
- AV valve opens
- isovolumetric contraction
- aortic valve closes
- filling
- AV valve closes
- aortic valve opens: 1. aortic valve closes
2. Isovolumetric relaxation
3. AV valve opens
4. filling
5. AV valve closes
6. isovolumetric contraction
7. aortic valve opens
2. Select all of the statements that are true regarding the
ventricular pressure volume relationship.
- Since the heart is compliant, increased preload can result in
increased stroke volume.
- Decreased compliance implies that for the same volume,
pressure in higher. - Afterload is set by the end-diastolic volume
and determines the point when the atrial-ventricular valve
opens.
- Sympathetic stimulation increases contractility and stroke
volume.

2024/2025 QUESTIONS AND ANSWERS.
- Decreased slope of the ESPVR line increases stroke volume
- Parasympathetic stimulation does not alter contractility.: -
Since the heart is compliant, increased preload can result in
increased stroke volume.
- Decreased compliance implies that for the same volume,
pressure in higher.
- Sympathetic stimulation increases contractility and stroke volume.
- Parasympathetic stimulation does not alter contractility.
3. Which of the following intrinsic or extrinsic changes would
result in a decrease in stroke volume?
- An increase in diastolic blood pressure
- Increased contractility
- Arterial constriction
- A decrease in ventricular compliance
- Venous constriction
- An increase in preload: - An increase in diastolic blood pressure -
Arterial constriction
- A decrease in ventricular compliance
4. Provided below are the pressures in the left atrium, left
ventricle, and aorta at a given point during the cardiac cycle of
three different NORMAL patients. Based on the three pressures,
what phase of the cardiac cycle is patient 1 in? (Filling, Ejection,
Isovolumetric Relaxation, Isovolumetric Contraction )
Based on the three pressures, what phase of the cardiac cycle is
patient 2 in? (Filling, Isovolumetric Relaxation, Ejection,
