- For the average healthy human, why is the pulse rate lower immediately upon standing compared the the pulse rate in the reclining position? (Mark all that apply) O When reclining, there is a gravitational force working on our body the allows the heart to exert less pressure to pump blood to the head without working against gravity When we stand up, immediately the pulse rate goes down due to the hearts current state of exerting less force while in the reclining position. O The heart has to work harder against gravity to pump blood to all regions of the body when in the reclining positionBelow is the client's resting 12-lead EKG.

Multiple Choice The autonomic nervous system initiates the heart's contractions. Sympathetic nerves release.norepinephrine at adrenergic nerve endings that decreases the activities of the sinoatrial and atrioventricular nodes. Parasympathetic nerves release acecholine at cholinergic nerve endings that decreases the activities of the sinoatrial and atrioventricular nodes. The heart is only regulated by the sympathetic nerves, not the parasympathetic nerves.
