The video tutorial explores the respiratory system, detailing how oxygen travels from the atmosphere into the bloodstream. It demonstrates the use of tools to examine a mammal's lungs, explaining the structure and function of the trachea, bronchi, bronchioles, and alveoli. The role of the diaphragm in lung inflation is discussed, along with the pleural membrane's function. The tutorial also covers how ventilators assist patients who cannot breathe unaided, providing necessary oxygen.
