Final answer:

If total peripheral resistance were to increase, the body could compensate by arterial vasoconstriction and venoconstriction to maintain mean arterial pressure.

Step-by-step explanation:

If total peripheral resistance were to increase, the body could compensate in several ways to maintain mean arterial pressure. Two possible compensatory mechanisms are arterial vasoconstriction and venoconstriction. Arterial vasoconstriction increases resistance in the arteries, while venoconstriction increases venous return to the heart. Both of these responses help increase blood pressure. In addition, the body may also increase stroke volume and heart rate, as well as increase blood volume, to maintain mean arterial pressure.
