Question

Explain the homeostatic feedback mechanisms that control ventilation and circulation to include the pacemaker of the heart.

Answer 1

Are you meaning ventricular fibrillation when you say ventilation? That in itself makes this a confusing question.

The homeostatic feedback mechanisms (there are several):

One you have the central nervous system which tells us when to breathe, when to move, when to pump blood or not pump blood (you get the picture)

Two you have the medulla oblongata which is the central regulator of these functions: breathing, circulation, digestion, swallowing, etc.

Three you have the inspiration and expiration which provides fresh oxygen to the blood supply.

Four you have the electrical impulses propogated by the SA node (pacemaker of the heart/also P Wave) that travels through Bachmann's Bundle to make the Atria contract and pump blood.

All of these pieces play an integral part in what I believe you're asking about. Let me know if I missed your question.
