Which of the following variation(s) control(s) blood flow to the heart?
1) Local metabolic control mechanisms
2) Local myogenic control mechanisms
3) Central neural innervation
A)1, 2, and 3
B)2 and 3 only
C)1 only
D)1 and 3 only

Quizplus · Accepted Answer

Local myogenic control mechanisms can regulate blood flow by responding to changes in pressure, while central neural innervation can regulate blood flow by responding to signals from the brain. Local metabolic control mechanisms can also regulate blood flow, but they typically only affect blood flow in specific tissues or areas of the body. Therefore, options 2 and 3 are both correct, while option 1 is not necessary for controlling blood flow to the heart.
