Study Notes
Respiratory Tract System
- The respiratory system facilitates gas exchange, allows breathing, produces sound, aids olfaction, and protects from foreign matter.
- Key functions include exchanging oxygen and carbon dioxide, moving air (breathing), and voice production.
- The function also includes assisting the sense of smell (olfaction), protecting the body from dust and microbes through mucus, cilia, and coughing.
Respiratory System Parts
- The respiratory system is composed of upper and lower parts.
- The Upper Respiratory Tract includes the nose, nasal cavity, laryngopharynx, and larynx.
- The Lower Respiratory Tract includes the trachea, bronchi, bronchial tree, and the lungs.
Upper Respiratory Tract
- It encompasses the structures involved in air intake and initial processing before reaching the lungs, such as the nasal cavity.
- Structures include the nasal cavity, pharynx (with its sections: nasopharynx, oropharynx, and laryngopharynx), and the larynx.
Nose
- The nose has important anatomical parts including the dorsum, alae, tip, nostrils (nares) and the columella.
- The nasal cavity has olfactory regions, respiratory regions, and the auditory tube opening.
- External nose components like the dorsum, alae, tip, nostrils, and columella.
Paranasal Sinuses
- Paranasal sinuses include frontal, ethmoidal, sphenoidal, and maxillary air sinuses.
Sinusitis
- Sinusitis involves inflammation of the sinus lining, commonly causing pressure in the facial area.
Pharynx
- The pharynx acts as a conduit for both air and food. The three parts include:
- Nasopharynx: functions only in respiration
- Oropharynx: involved in respiration and digestion.
- Laryngopharynx: passageway for air and food.
Larynx
- The larynx is a cartilaginous structure located between the pharynx and trachea, supporting the voicebox.
Lower Respiratory Tract
- The lower respiratory tract begins past the larynx, including the trachea, bronchi, bronchial tree, and the lungs.
- The trachea is a tube connecting the larynx to the bronchi.
- The trachea branches into two primary bronchi, one for each lung.
- The bronchi further divide into secondary and tertiary bronchi. The bronchi create the bronchial tree.
- Terminal bronchioles lead to alveoli, tiny air sacs where gas exchange takes place.
Lungs
- Lungs have lobes (superior, middle, and inferior) that are further subdivided into smaller units.
- Right lung has 3 lobes, while Left lungs have 2 lobes.
- Pleura membranes surrounding the lungs, vital for smooth lung movement during respiration, consist of visceral and parietal pleura and pleural cavity.
