A 52 year old man presents with black tarry stools and hypotension. an endoscopy is ordered and reveals a bleeding ulcer in the
antrum of the stomach. baroreceptor-induced compensation for the mild hemorrhage will cause which of the following values to be lower than before the hemorrhage?
The decrease venous capacitance will increase preload due to increased total
peripheral resistance. This fall in blood pressure and blood volume is produced
by hemorrhage, which causes the baroreceptor<span> reflex to escalate the activity of the
sympathetic nervous system</span> and
decreases the activity of the parasympathetic nerves innervating the
<span>heart.</span>
