Study Notes
Lung Anatomy
- Right lung has three lobes: superior, middle, and inferior.
- Left lung has two lobes: superior and inferior, with a unique cardiac notch for the heart's space.
- Horizontal fissure separates the superior and middle lobes of the right lung.
- Oblique fissure separates the middle lobe from the inferior lobe in the right lung and also divides the lobes of the left lung.
Respiratory Structures
- Thyroid gland is an endocrine gland located in the neck, playing a significant role in metabolism.
- Diaphragm is the primary muscle of respiration, separating the thoracic cavity from the abdominal cavity.
- Apex refers to the topmost part of the lung, while the base is the lower portion resting on the diaphragm.
Pharyngeal Regions
- Nasopharynx is the upper part of the pharynx, located behind the nasal cavity.
- Oropharynx is the middle part, located behind the oral cavity.
- Laryngopharynx is the lower part, connecting the pharynx to the larynx.
Larynx Components
- Larynx houses vocal cords and is crucial for sound production.
- Cricoid cartilage provides structural support, located just below the thyroid cartilage.
- Thyroid cartilage is the largest cartilage of the larynx, forming the Adam's apple.
- Hyoid bone supports the tongue and is unique as it doesn't articulate directly with other bones.
- Epiglottis acts as a flap to cover the trachea during swallowing, preventing food from entering the airway.
Oral Structures
- Tongue is a muscular organ crucial for taste, manipulation of food, and speech.
- Uvula hangs at the back of the throat, aiding in swallowing and speech.
- Soft palate is the soft, flexible part at the back of the roof of the mouth.
- Hard palate is the bony front part of the roof of the mouth.
Nasal Anatomy
- Inferior, middle, and superior nasal conchae are bony structures inside the nasal cavity that humidify and filter air.
Bronchial Tree
- Primary bronchi branch from the trachea into right and left lungs.
- Secondary bronchi subdivide further into lobar bronchi, serving respective lobes.
- Tertiary bronchi lead to smaller airways called bronchioles.
Lung Capacities and Volumes
- Total Lung Capacity (TLC) ranges from 4200-6000 ml, includes all lung volumes.
- Vital Capacity (VC) consists of Tidal Volume, Inspiratory Reserve Volume, and Expiratory Reserve Volume.
- Inspiratory Reserve Volume (IRV) is the extra air that can be inhaled beyond normal tidal volume.
- Tidal Volume (TV) is the volume of air exchanged during normal breathing.
- Residual Volume (RV) is the air that remains in the lungs after maximal exhalation, about 1200 ml.
- Expiratory Reserve Volume (ERV) is the air that can still be exhaled after normal exhalation.
