Question

What is the benefit of residual volume in the respiratory process?

Answer 1

The exchange of oxygen and carbon dioxide in living organisms take place by a process known as the respiratory system and the exchange of gases occurs through the larynx, trachea, bronchial tubes and lungs in the respiratory system. There are two types of the respiratory system external respiratory respiration and internal respiratory system.

Complete answer: The respiration system helps to regulate the blood pH, supplies the body with oxygen and exhales out carbon dioxide, rids the body of some excess water and heat, filters inspired air, contains receptors for smell and produces the sound in the respiration system. The gases pass into the lungs throughout the process of inhalation and during exhalation, gases come out of the respiration system. There are three sections in the pharynx, which includes the nasopharynx, oropharynx and the laryngopharynx. The lungs would be extremely large during the time of the gas exchange and some air remains inside the lungs during the process of gases exchange in the respiratory system. The fluctuations in respiratory gases are prevented with the help of residual volume that is also found inside the respiratory system. After the maximum expiration, the residual volume functions open inside the alveoli. In the lungs after full exhalation, the residual volume remains inside the lungs and helps to check the proper functioning of the lungs during the respiratory problem.

Note: Gaseous exchange in the lungs is performed with the help of sac-like structures called alveoli. The exchange of gases takes place via the process called diffusion. The blood carries both oxygen and carbon dioxide.
