At least two body systems are needed to perform the function of breathing because to ensure breathing, the body performs two respiratory movements: inspiration, which is the entry of air into the lungs, and expiration, which is the elimination of carbon dioxide. Pulmonary breathing is a process in which air enters our lungs and is subsequently eliminated. involving muscles and gaseous reactions.
<h3>What is the path of air inside the human body?</h3>
The air penetrates through the nasal passages, passes through the pharynx, larynx and trachea, bronchi, reaching the lungs where it travels through the bronchioles until reaching the alveoli, where gas exchange takes place. The difference between inspired and expired air is in the concentration of oxygen and carbon dioxide.
With this information, we can conclude that The entire process of gas exchange in the body, which is called breathing, takes place in three basic steps, which are pulmonary ventilation, which corresponds to the flow of air in and out of the lungs.
