When blood pressure decreases, baroreceptors send impulses to the cardioacceleratory center, which increases heart rate and stroke volume via the sympathetic nerve.
Quando la pressione sanguigna diminuisce, i barorecettori inviano impulsi al centro cardioacceleratorio, che aumenta la frequenza cardiaca e la gittata sistolica attraverso il nervo simpatico.
| Front | What happens when blood pressure decreases? |
|---|---|
| Back | - baroreceptors in aortic arch and carotid arteries - detect decrease in blood pressure - receptors send impulses to cardio acceleratory centre in medulla oblongata - CAC sends more impulses to SA node - via sympathetic nerve - heart rate and stroke volume increase |
