Document Summary
Transport mechanism: of oxygen and carbon dioxide in the blood. Regulation of blood ph: altered by changing blood c02 levels. Production of chemical mediators: angiotensin-converting enzyme (ace) Voice production: movement of air past vocal folds, makes sound and speech. Olfaction: occurs when airborne molecules are drawn into the nasal cavity. Protection: preventing microorganisms from entering, removing them from respiratory surfaces. Upper respiratory tract: nasal cavity, pharynx (throat, larynx. Lower respiratory tract: trachea, bronchi, lungs. Bony ridges in the nose: superior, middle, inferior. Lined with stratified squamous epithelium: contains hairs. Channels created from the conchae: superior, middle, inferior. Cavities in the skull: makes it lighter. Contains olfactory epithelium: for sense of smell. Contains pseudostratified ciliated columnar with goblet cells: warms air due to high vascularity, mucous and tears moistens air and traps dust, cilia moves mucous towards pharynx. A muscular tube: extends from the choanae to esophagus. Has tonsils immunological functions: palatine, lingual and pharyngeal tonsil.
