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.
