Pulmonary Surfactant                                          Introduction Pulmonary surfactant is a surface-active organic complex of phospholipids and proteins. It reduces surface tension, prevents alveoli collapse after expiration, and makes respiration easy and smooth. Surfactant is crucial for life as it prevent atelectasis.

                                           Tidal Volume-Explained There are several lung volume types, some static and some dynamic. Tidal volume is one of the essential volumes.  Tidal volume and lung capacity are two critical aspects of overall health. Understanding tidal volume is crucial for optimizing respiratory health and increasing full fitness potential. It is essential in determining how much oxygen enters the body and how much carbon dioxide exits. Tidal volume is the amount of air that is inspired or expired during normal breathing.
