What anatomic site regulates the pulse rate and force?

Question

Quizplus · Accepted Answer

The cardiac sinoatrial node, located in the right atrium of the heart, is responsible for initiating and regulating the heartbeat, including the pulse rate and force. It acts as the natural pacemaker of the heart, sending electrical signals that cause the heart muscle to contract and pump blood throughout the body.

The other options listed are involved in other physiological processes, such as regulating temperature (thermoregulatory center), maintaining oxygen levels in the blood (peripheral chemoreceptors), or controlling blood flow through the heart (cardiac atria and valves), but they are not specifically responsible for regulating the pulse rate and force.
