Study Notes
Components of the Respiratory System
- Includes the nasal cavity, air sinuses, pharynx, larynx, trachea, bronchi, lungs, and alveoli.
Function of the Respiratory System
- Facilitates gas exchange, allows for the sense of smell, and enables voice production.
Upper Respiratory Tract
- Comprises the nasal cavity, pharynx, larynx, and air sinuses.
Lower Respiratory Tract
- Consists of the trachea, bronchi, bronchioles, and alveoli.
Nasal Cavity
- Divided into right and left halves by the nasal septum. Each half has olfactory and respiratory parts.
- Features three conchae: superior, middle, and inferior, which create spaces called meatuses.
- Functions include warming, moistening, and cleaning inspired air.
Paranasal Air Sinuses
- Located in the maxillae, frontal, sphenoid, and ethmoid bones.
- Open into the nasal cavities and help condition inspired air, provide voice resonance, and lighten the skull.
Epistaxis
- Refers to nosebleeds, with common risk factors including vascular issues, infections, inflammation, trauma, and neoplasms.
Sinus Names
- Four paranasal sinuses: Maxillary, Frontal, Sphenoid, Ethmoid.
- Causes of sinusitis include inflammation, allergies, and polyps.
Pharynx
- A muscular tube positioned behind the nasal and oral cavities, divided into three segments: nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
- Contains the adenoid tonsil and eustachian tube openings, which help equalize pressure in the ear.
Oropharynx
- Situated behind the oral cavity and contains palatine tonsils.
Laryngopharynx
- Located behind the larynx, with the piriform fossa as a common site for lodging foreign objects.
Larynx
- Consists of cartilages, ligaments, membranes, and muscles, with key cartilages including the thyroid, cricoid, and epiglottis.
- Responsible for voice production via vocal cords.
Trachea
- A cartilaginous tube that begins in the neck and divides into right and left bronchi.
- The right bronchus is wider and shorter, while the left is narrower and longer, with both dividing into smaller bronchioles.
Alveoli
- Serve as the functional units of the respiratory system, facilitating gas exchange.
Lungs
- Soft, spongy organs covered by pleurae (visceral and parietal).
- The hilum of the lung transmits bronchi, pulmonary arteries, and veins.
Pleural Effusion
- Characterized by abnormal fluid accumulation in the pleural cavity, generally due to inflammation, tuberculosis, malignancy, or pneumonia.
Pneumothorax
- Occurs when air enters the pleural cavity, often from penetrating wounds.
Hydrothorax and Hemothorax
- Hydrothorax refers to fluid accumulation in the pleural cavity, while hemothorax involves blood collection.
Lung Differences
- Right lung has three lobes, is short and wide, lacking a cardiac notch.
- Left lung has two lobes, is long and narrow, and possesses a cardiac notch.
Muscles of Respiration
- Diaphragm is the primary muscle of inspiration.
- External intercostals aid in inspiration, while internal intercostals facilitate expiration.
