heart rate and stroke volume based on physical and chemical demands to ensure
adequate cardiac output - ANSWER-The ANS increases or decreases

reducing SA node firing and slowing AV nodal conduction. - ANSWER-The

increases heart rate and stroke volume by:

vasoconstrict - ANSWER-SNS: Stimulating alpha (a) receptors in the peripheral vessels
to

increase SA node firing, increase AV nodal conduction, and increase contractility -
ANSWER-SNS Stimulating the Beta 1 (B1) receptors in the heart to
