Document Summary
Basic speech science 2013 4th exam review sheet. Boyle"s law: volume and pressure are inversely related, raise volume lower pressure & vice versa, unequal pressures will always equalize if possible. Airways: nasal/oral cavity pharynx larynx trachea bronchi bronchioles alveoli. Alveoli = air exchange (air rich in carbon dioxide exchanged for air rich in oxygen) Medulla oblongata: reflex seat for respiration in the brain, initiates nerve impulses to certain thoracic muscles, signaled when fresh oxygen is needed. Thorax (vertebrae, ribs, sternum, diaphragm): thorax contains lungs, heart, and respiratory airways, back is spinal column. Pleural linkage: costal (parietal) pleura: membrane that lines the rib cage, thin layer of viscous fluid (sticky, adhesive) between the two. Terms for lung volumes (approximate values in liters) Tidal volume: the amount of air exchanged during the ins and outs of quiet breathing (~5 liters) Vital capacity: the amount of air exchanged during a maximum inhalation and exhalation (~5 liters)
