Section 1: Introduction to Pneumology
- What are the main functions of the respiratory system?
- a. Gas exchange:
- b. Acid-Base Balance:
- c. Phonation:
- d. Pulmonary defense mechanisms:
- e. Pulmonary metabolism and the handling of the bioactive materials:
The cells of the lung metabolize substrates to supply nutrients and energy for their own maintenance. The pulmonary capillary's endothelium contains a great number of enzymes that can produce, metabolize or modify naturally occurring vasoactive substances.
