Study Notes

Respiratory System Overview

The respiratory system is composed of three main parts: upper, middle, and lower respiratory tracts.

Upper Respiratory Tract

Includes the nose, paranasal sinuses, pharynx, and larynx.
Provides entry for inhaled air.
Mucus-producing cells trap bacteria and particulates.
Cools and moistens the inhaled air.
The larynx functions as the organ of speech.

Middle Respiratory Tract

Comprises the trachea, supported by cartilaginous rings for structure.

Lower Respiratory Tract

Contains the right and left main bronchi, leading to bronchioles and alveoli.
Alveoli are lined with mucous for protection, except in the alveoli themselves.

Alveoli Functions

Produce pulmonary surfactant, a mixture of lipids, proteins, and carbohydrates.

Tuberculosis

Caused by the bacterium Mycobacterium tuberculosis.
Can be acute or chronic, leading to granulomas, fibrosis, and cavitation.
Abscesses result from the destruction and dilation of bronchial walls due to pus accumulation.
Hematogenous spread can lead to tuberculosis in distant sites such as the urogenital tract or brain.
Bacterial dissemination may also result in intestinal tuberculosis.
