Function of pace maker is

To regulate the formation of urine
To regulate the process of digestion
To initiate heart beat

The correct answer is C. To initiate heart beat.

A pacemaker is a small device that is implanted in the chest to regulate the heart beat. It does this by sending electrical signals to the heart muscle, which cause it to contract and pump blood.

The other options are incorrect because:

  • Option A is the function of the kidneys.
  • Option B is the function of the digestive system.
  • Option D is the function of the respiratory system.
