Pulmonary Physiology, Introduction, Dr. D. Penney

Pulmonary Physiology - Introduction
Module 1 - Dr. D. Penney

Pulmonary physiology focuses on the function of the lungs in gas exchange. Oxygen and carbon dioxide exchange at the lung, carriage by the blood, and O2 delivery to peripheral tissues are fundamental since humans are aerobic organisms.

In our discussion of this topic we will consider gas pressures and volumes, respiratory pressures and volumes, the pulmonary circulation, gas diffusion and transport, oxygen delivery and uptake, and metabolic and defense systems of the lung.

Pulmonary physiology is one of the most important areas of human function - and it is also one of the most interesting. As in the case of the heart/circulation, we are presented with a pump and its associated plumbing through which a mixture of gases flow. Many of the same physical principles apply in the two systems.


The Objectives of this learning exercise is to provide you with facts and concepts about the normal functioning of the pulmonary system such that you are able to:

  • Understand more advanced pulmonary material in the future.
  • Integrate an understanding of pulmonary physiology into your future career.
  • Perform credibly on the course examinations.
