Human Respiratory System Lungs With Diaphragm Anatomy Stock Photo Alamy Learn the anatomy and physiology of the respiratory system, including the lungs, chest wall and diaphragm, in this educational video. For a free alternative, one may easily use luce & culver (1982) they cover the same ground, but with more detail regarding the effects of lung pathology on respiratory muscle use. for just the chest wall muscles, one could not do better than de troyer et al (2005). for the diaphragm, poole et al (1997) is best, though it is paywalled.
Human Respiratory System Lungs With Diaphragm Anatomy Stock Photo Alamy The lungs, chest wall, and diaphragm are all involved in respiration, both (a) inhalation and (b) expiration. (credit: modification of work by mariana ruiz villareal) figure 3. a tissue layer called pleura surrounds the lung and interior of the thoracic cavity. (credit: modification of work by nci) the chest wall expands out and away from the. Respiratory zone: respiratory bronchioles, alveoli. breathing cycle. inspiration diaphragm contracts and pulls down, intercostal muscles contract and expand the rib cage > air enters the lungs. expiration diaphragm relaxes and goes up, intercostal muscles relax and rib cage collapses > air exits the lungs. Figure 39.9.1 39.9. 1: inhalation and exhalation: the lungs, chest wall, and diaphragm are all involved in respiration, both (a) inhalation and (b) expiration. during this process, the chest wall expands out and away from the lungs. the lungs are elastic; therefore, when air fills the lungs, the elastic recoil within the tissues of the lung. Figure 9.4.1 9.4. 1: (a) birds have a flow through respiratory system in which air flows unidirectionally from the posterior sacs into the lungs, then into the anterior air sacs. the air sacs connect to openings in hollow bones.
