Select any of the following that will result in a response of increasing blood pressure:


Astimulation of aortic baroreceptors
Bnerve impulses along cardiac nerves
Cactivation of the CAC in the medulla oblongata
Drelease of the neurotransmitter norepinephrine at the SA and AV nodes
Eincrease in carbon dioxide concentration in the blood passing through the aorta

Verified Answer :

Final answer:

Several factors can increase blood pressure, including nerve impulses along cardiac nerves, activation of the CAC in the medulla oblongata, and the release of norepinephrine. Additionally, an increase in carbon dioxide concentration in the blood can also elevate blood pressure. However, stimulation of aortic baroreceptors generally reduces blood pressure.


Explanation:

Understanding Blood Pressure Regulation

Blood pressure regulation is a complex process influenced by various physiological factors. Among the options provided, certain factors can indeed lead to an increase in blood pressure:

  1. Nerve impulses along cardiac nerves: These impulses enhance heart rate and contractility, leading to increased cardiac output and thus higher blood pressure.
  2. Activation of the CAC in the medulla oblongata: The Cardioacceleratory Center (CAC) activates sympathetic nervous system responses that constrict blood vessels and increase heart rate, both of which elevate blood pressure.
  3. Release of norepinephrine at the SA and AV nodes: Norepinephrine increases heart rate and force of contraction, resulting in elevated blood pressure.
  4. Increase in carbon dioxide concentration in the blood passing through the aorta: High levels of CO2 can trigger a reflex that increases heart rate and constricts blood vessels to enhance oxygen delivery, consequently raising blood pressure.

The stimulation of aortic baroreceptors, on the other hand, typically occurs in response to increased blood pressure; their stimulation usually leads to a decrease in heart rate and blood pressure as part of a negative feedback mechanism.
