Function – 1. To reduce the surface tension of alveoli mainly during expiration, thus reduces the work of lung inflation. 2. Waterproofing. Surfactant synthesis starts after 26 weeks of fetal life. Therefore premature infants,with insufficient surfactant suffer from HMD.
18 cze 2009 · The lung is uniquely designed to accomplish its major functions of movement of air and the delivery of oxygen to and removal of carbon dioxide from the circulation.
• relate the function of any portion of the respiratory tract to its gross and microscopic anatomy. The term respiration has three meanings: (1) ventilation of the lungs (breathing), (2) the exchange of gases between air and blood and between blood and tissue fluid, and (3) the use of oxygen in cellular metabolism. In this chapter, we
Understanding the structure and function of the lungs, along with the common respiratory diseases that a ect them, underscores the importance of maintaining respiratory health through lifestyle choices, regular medical check-ups, and prompt treatment of respiratory conditions.
5 paź 2018 · The primary function of the lungs is gas exchange. Knowledge of the anatomy and airflow pathways is important to understand how gas moves to the blood from the atmosphere. Human airway anatomy starts at the oro- and nasopharynx and terminates at the alveoli.
The lung is uniquely designed to accomplish its major functions of movement of air and the delivery of oxygen to and removal of carbon dioxide from the circul ation.
The main function of the lungs is to perform the exchange of oxygen and carbon dioxide with air from the atmosphere. To this end, the lungs exchange respiratory gases across a very large epithelial surface area—about 70 square meters—that is highly permeable to gases.
