Vedclass · Answer

(A) The parasympathetic nervous system is part of the autonomic nervous system that acts to 'rest and digest'.In the context of the heart,the parasympathetic nervous system (via the vagus nerve) releases acetylcholine.This neurotransmitter binds to receptors on the heart,which leads to a decrease in the heart rate.Additionally,it reduces the force of contraction,thereby decreasing the cardiac output (the volume of blood pumped by the heart per minute).Therefore,both the heart rate and the cardiac output are decreased.
