Homeostasis
If blood pressure is detected to be lower than required to optimally perfuse the tissues, what homeostatic response would occur?
The vasomotor centre would be inhibited and so the heart rate would decrease.
Vasoconstriction would occur; hence, total peripheral resistance would increase.
The strength of myocardial contraction would increase and so stroke vol-ume would decrease
Smooth muscle in the walls of veins would relax resulting in vasodilation.
Vasoconstriction would occur; hence, total peripheral resistance would increase.
The homeostatic response to decreased blood pressure is to undertake action to increase blood pressure. Vasoconstriction would achieve this by increasing the peripheral resistance. Choices A and D are the opposite of what would happen.
