Study Notes
Respiratory System Anatomy and Function
- The nasal cavity humidifies and warms inspired air, and ciliated mucosal cells remove contaminated mucus.
- The pharynx is a skeletal muscle tube connecting the nasal cavity and mouth to the larynx and esophagus, divided into nasopharynx, oropharynx, and laryngopharynx regions.
- The larynx attaches to the hyoid bone, functions in airway patency, air and food routing, and voice production.
- The trachea is a flexible tube composed of mucosa, submucosa, and adventitia layers, leading into the bronchi.
- The bronchi warm, cleanse, and saturate air, branching into secondary bronchi and further subdivisions within the lungs.
- The bronchial tree's tissue walls change as the air passages become smaller, with alterations in cartilage, epithelium, and smooth muscle.
- The respiratory zone is defined by the presence of alveoli, providing a large surface area for gas exchange.
- The respiratory membrane, composed of alveolar and capillary walls, facilitates gas exchange by simple diffusion and secretes surfactant.
- Pulmonary ventilation includes quiet and forced respiration, characterized by inspiratory and expiratory phases.
- Inspiratory and expiratory muscles, including the diaphragm, intercostal, and accessory muscles, are involved in the respiratory process.
- Brainstem respiratory centers, including the ventral and dorsal respiratory groups, and the pontine respiratory group, control automatic breathing.
- Central and peripheral input, including chemoreceptors and stretch receptors, regulate respiration and maintain pH levels in the blood.
