NSER 7110 EXAM QUESTIONS AND ANSWERS LATEST UPDATE 2025-2026
cardiac output - Answers volume of blood ejected by the heart each minute
CO is determined by - Answers heart rate and stroke volume
heart rate and stroke volume are controlled by - Answers autonomic nervous system
The heart is under constant control of the parasympathetic nervous system via - Answers the
vagus nerve
The PNS is the - Answers "zen" of the ANS, keeping everything mellow
the sympathetic nervous system (SNS) is the - Answers "stimulant" of the ANS.
The ANS increases or decreases - Answers heart rate and stroke volume based on physical and
chemical demands to ensure adequate cardiac output
The parasympathetic nervous system decreases heart rate by - Answers reducing SA node firing
and slowing AV nodal conduction.
PNS minimally decreases stroke volume by decreasing contractility in the - Answers atria
PNS does not affect contractility in the - Answers ventricles
The sympathetic nervous system increases heart rate and stroke volume by: - Answers 1.
Stimulating alpha (a) receptors
2. stimulating the Beta 1 (B1) receptors
SNS: Stimulating alpha (a) receptors in the peripheral vessels to - Answers vasoconstrict
SNS Stimulating the Beta 1 (B1) receptors in the heart to - Answers increase SA node firing,
increase AV nodal conduction, and increase contractility
SNS Stimulating the Beta 1 (B1) receptors in the heart also - Answers stimulates Beta 2 (B2) in
the lungs to bronchodilate
Baroreceptors - Answers sensory receptors located in the aortic arch and carotid arteries
Baroreceptors detect changes in - Answers BP
Baroreceptors detect changes bp and respond accordingly - Answers with either a
parasympathetic or a sympathetic reflex action.
Chemoreceptors located in the - Answers aortic arch and carotid arteries
