Question bank: Human Body: Respiratory System

Describe the process of inspiration in the human respiratory system, identifying the organs and structures responsible for this action. Then, explain the importance of the humidity and heating of the air we breathe and how the respiratory system performs these functions to protect the lower airways.

The respiratory system plays an essential role in obtaining oxygen and eliminating carbon dioxide, maintaining the blood balance in the body. When performing daily activities applying knowledge from the Natural Sciences, it is important to protect the organs of the respiratory system from various pollutants. Among the organs listed below, which one has the primary function of filtering, humidifying, and warming the air we breathe?

Breathing is an essential physiological process for the maintenance of life. There are several mechanisms for regulating this function that allow controlling the frequency, depth, and tidal volume of breathing through internal (homeostatic) and external (sensory) stimuli. Which systems are responsible for transmitting these stimuli?

In the work environment, the use of personal protective equipment (PPE) is essential to ensure the safety of workers exposed to chemical and biological substances involving the risk of respiratory system contamination. Considering the structure of the human respiratory system, which of these organs is responsible for filtering and humidifying the air that enters the body during breathing?
