The respiratory rate and the depth of inspiration are regulated by the medulla oblongata and pons However, these regions of the brain do so in response to systemic stimuli. Breathing occurs due to repeated contractions of a large muscle called the diaphragm The rate of breathing is regulated by the brain stem It monitors the level of carbon dioxide in the blood and triggers faster or slower breathing as needed to keep the level within a narrow range. An important characteristic of the human respiratory system is its ability to adjust breathing patterns to changes in both the internal milieu and the external environment.
Learn how the body’s muscles and nervous system help control your breathing. To achieve this tight regulation, peripheral receptors send information to a cns respiratory center whose output adjusts initiation, duration, depth, and rate of breathing The intercostal muscles and diaphragm are skeletal muscles that will not contract unless stimulated. The regulation of respiration involves a complex interplay between neural control centers in your brain, chemical sensors throughout your body, protective reflexes, and adaptive mechanisms that respond to changing demands like exercise. Respiration is an essential physiological activity that preserves the optimum level of oxygen and carbon dioxide within the body This article elaborates on mechanisms and factors for the control of respiration, so it's a very essential material for examinations like neet preparation.
