what portions of the respiratory system are referred to as anatomical dead space

Bronchi and SubdivisionsĪirways branch ☒3x → bronchial tree. Maneuver, air in lungs used to pop out obstruction. Homeostatic Imbalance - Smoking inhibits and destroys cilia Trachealis flexibility allows esophagus to expand Submucosa, connective tissue layer, seromucous glands, 16-Ģ0 C-shaped cartilage rings encased by adventitia, outerĬartilage rings ensure trachea remains open during pressureĬhanges. Mucosa, contains goblet cells, cilia and is elastic. Conducting zone: respiratory passageways.Respiratory zone: site of gas exchange, bronchioles,.22 Lower respiratory system consists of conducting and respiratory zone structures Laryngopharynx - Food and air passage, continuous withĮsophagus posteriorly. Oropharynx - Food and air passes, epithelium different, for more ‘trauma’ due to food stuffs etc. Pharyngeal tonsil traps and destroys pathogens. ‘Throat’, 13 cm, walls composed of skeletal muscle, three

Paranasal Sinuses - Nasal cavity surrounded by ring of Increases mucosal surface area, enhances air turbulence,įorcing particles onto mucous membranes. Nasal conchae: scroll-like mucosa covered projections. Ciliated cells moveĬontaminated mucous to throat to be swallowed. Epithelial cells secreteĭefensins → natural antibiotic. Glands/cells secrete fluids with enzymes, lysozyme

Respiratory mucosa: most nasal cavity, contains gobletĬells that rest on lamina propria, which is richly supplied.

Olfactory mucosa: superior region, smell receptors.

Rest nasal cavity lined with two types of mucous membranes: Skin with sweat glands, hair follicles → Vibrissae → filter

Internal Respiration: diffusion Ox from blood to tissue, COĢ2 Upper Respiratory System Warms, Humidifies, and Filters Air Nose and Paranasal Sinusesįunctions nose: airway respiration, moistens + warms air, filtersĪnd cleans air, resonating chamber for speech, houses.

Transport Respiratory Gasses: Ox lungs to tissue cells,ĬO2 tissue cells to lungs (cardiovascular system).

External Respiration: Ox from lung to blood, CO 2 blood to.

Pulmonary Ventilation: breathing, inspiration and.

Major function is supply body with ox and dispose of CO 2 ,Īccomplished by 4+ processes collectively called respiration: Warning: TT: undefined function: 32 Chapter 22 The Respiratory System Referred images found at the back
