The Hering-Breuer reflex is a protective mechanism that prevents over-inflation of the lungs during breathing. During exercise, as the rate and depth of breathing increase, stretch receptors in the lungs send signals to the brain to regulate respiratory patterns. Although the reflex is less active during intense exercise, it helps maintain appropriate ventilation and prevents damage to lung tissue by signaling when to inhibit further inhalation. This allows for efficient gas exchange while accommodating the increased oxygen demand of the body.

The lung is the organ involved in Hering - Breur reflex.
The Hering-Breuerinflation reflex, named for Josef Breuer and EwaldHering, is a reflex triggered to prevent over-inflation of the lung

The primary purpose of this reflex is to limit the possibility of overinflating the lungs.
The Hering-Breuer reflexes are also known as the "inflation reflex" and "deflation reflex." These reflexes help regulate breathing by preventing over-inflation of the lungs during inhalation and promoting exhalation when the lungs are deflated. They play a crucial role in maintaining respiratory rhythm and ensuring efficient gas exchange.
The reflex associated with the sensory stimulation of the pulmonary stretch receptors is known as the Hering-Breuer reflex. It is responsible for inhibiting inspiration to prevent overinflation of the lungs, promoting expiration and maintaining normal breathing patterns.
For an adult male, the most a lung can hold is about 6 liters of air. There is a reflex in the body that will prevent overstretching of the lungs. This is called the Hering–Breuer inflation reflex which is triggered by receptors on the surface of the lung and carried via the Vagus nerve.
The patellar reflex is generally more vigorous after exercise due to increased muscle activation and elevated excitability of the nervous system. This can result in a quicker and more pronounced response when the tendon is struck, leading to a stronger contraction of the quadriceps muscle and a more prominent knee jerk reflex.
Factors that influence the respiratory center in the brain include the levels of carbon dioxide, oxygen, and hydrogen ions in the blood, as well as input from chemoreceptors in the carotid arteries and aortic arch. Other factors such as emotional stress, physical activity, and temperature can also influence the respiratory center.
