[{'content': 'Which of the following is NOT caused by sympathetic stimulation? \nSelect and explain. \nA. Increased BP, B. Increased HR, C. Increased venous capacitance, D. Increased total peripheral resistance', 'role': 'user'}, {'content': 'Answer: C \nExplanation: Increased venous capacitance is NOT caused by sympathetic stimulation. Impoant effects of increased sympathetic stimulation: Aeriolar vasoconstriction Increased stroke volume Increased hea rate Venoconstriction and decrease in venous capacitance The increase in mean systemic filling pressure is caused mainly by venous contraction. All these efffects together about an increased aerial pressure. Ref: Guyton and Hall 13th edition Pgno: 260', 'role': 'assistant'}]
