Hello, this is Professor Honey. This video explains lung volume and capacity, as well as the principles of gas exchange. Lung Volume and Capacity: Lung Volume [00:13]: This refers to the amount of air the lungs can hold. Tidal Volume (TV) [01:45]: The amount of air inhaled or exhaled during a normal breath (approximately 500 ml) Inspiratory Reserve Volume (IRV) [02:51]: The additional amount of air that can be inhaled after a maximal inhalation (approximately 3,100 ml) Expiratory Reserve Volume (ERV) [04:39]: The additional amount of air that can be exhaled after a maximal exhalation (approximately 1,200 ml) Residual Volume (RV) [04:50]: The amount of air remaining in the lungs after a maximal exhalation (approximately 1,200 ml) Lung Capacity [00:13]: The sum of two or more lung volumes. Inspiratory Capacity (IC) [05:32]: Tidal volume + Inspiratory reserve volume (approximately 3,600 ml) Functional Residual Capacity (FRC) [06:26]: Expiratory reserve volume + Residual volume (approximately 2,400 ml) Vital Capacity (VC) [08:06]: Tidal volume + Inspiratory reserve volume + Expiratory reserve volume (approximately 4,800 ml) Total Lung Capacity (TLC) [08:42]: Vital capacity + Residual volume (approximately 6,000 ml) Gas Exchange: Diffusion [10:07, 11:12]: The movement of gases from areas of high partial pressure to areas of low partial pressure. Gas exchange in the lungs occurs based on this principle. External Respiration [10:48]: Gas exchange between the alveoli and capillaries. Internal Respiration [10:52]: Gas exchange between the blood and tissue cells. The video also briefly discusses osmosis [20:33] and active transport [21:28].
