Question 1

stroke volume X heart rate

Answer 1

cardiac output

Question 2

baroreceptors monitor blood pressure located in the

Answer 2

aorta and carotid sinus

Question 3

if BP increases baroreceptors know->

Answer 3

goes to medulla
activate vagus nerve to activate parasympathetic
goes back to normal

Question 4

if BP goes down afferent info->

Answer 4

medulla
cardiac nerve
releases norepinephrine
HR increases
cardiac output increases
normal

Question 5

BP detected by baroreceptors

Answer 5

sends afferent info
to medulla
to sinal atrial node
para or sympathetic
