.1
Explain the feedback mechanisms that control ventilation and circulation to include
the pacemaker of the heart.

Respuesta :

It should be noted that the homeostatic feedback mechanisms that are important to regulate the ventilatory pattern of respiration involves the medulla and the pons.

Homeostatic feedback mechanisms.

The pons are divided into two groups. Firstly, the pneumotaxic center sends signals that inhibit inspiration as it limits the activity of the phrenic nerve. Due to this, the signals of the apneustic center and the tidal volume decreases.

Secondly, the apneustic center signals inspiration for deep and long breaths and controls the intensity of breathing. The stretch receptors of the pulmonary muscles inhibit the apneustic center, therefore, it increases tidal volume.

Also, the medulla has two functional regions as well which are the ventral respiratory compartment, that stimulates expiratory movements, and the dorsal respiratory region that triggers inspiratory movements.
