Respiratory System Lab New Youtube This is the new version of the respiratory system for the anatomy and physiology ii lab. Normal quiet breathing moves approximately 500 ml of air into and out of the lungs with each breath. inspiratory reserve volume. the amount of air that can be taken in forcibly over the tidal volume is the inspiratory reserve volume, which is normally between 2100 ml to 3200 ml. expiratory reserve volume.
Lab 9 Respiratory System Hbs Lab 9 Respiratory System Review She Introduction: breathing is an involuntary event. humans, when they are not exerting themselves, breathe approximately 15 times per minute on average. the primary function of the respiratory system is to deliver oxygen to the cells of the body’s tissues and remove carbon dioxide, a cell waste product. The respiratory bronchioles have a diameter of 0.5 millimeters and feature a few alveoli scattered along their walls. the epithelium here remains low cuboidal. each respiratory bronchiole branches into between 2 and 11 alveolar ducts that still contain smooth muscle fibers in their walls. Functionally, the respiratory system can be divided into the conducting zone, terminating at the terminal bronchioles; then air flows into the respiratory zone, where the actual gas exchange occurs. though we view each system individually in this lab, it is important to keep in mind that all organ systems overlap and work together in such a way. In contrast to the conducting zone, the respiratory zone includes structures that are directly involved in gas exchange. the respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole (figure 22.10), which then leads to an alveolar duct, opening into a cluster of alveoli.
