The larynx is at the superior (or cephalad) end of the trachea and is located just below the epiglottis and glottic opening. This is due to the influence of the hormone testosterone, which stimulates the overall growth of the larynx resulting in a deeper voice with time. These muscles are divided into 2 groups: the internal intercostal muscles and the external intercostal muscles. (Assume that her running direction is the positive direction.)

The difference in partial pressures causes the gases to diffuse passively along their pressure gradients from high to low pressure through the simple squamous epithelium lining of the alveoli. The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the bodys airwaythe respiratory tract through which air moves. It plays a vital role in the respiratory tract by allowing air to pass through it while keeping food and drink from blocking the airway. E) 6000 mL, Oxygen binds with hemoglobin in the blood to form: pg. aperture. This process is called obligate nose breathing. c. tonsils moisten the air entering the respiratory passageways pg. 440, The superior portion of each lung is the __________. c. expiratory reserve volume Several cartilage structures make up the larynx and give it its structure.
