Week 6: Respiratory System – Anatomy

Learning Objectives

1. Describe the gross anatomical features of the respiratory tract.
2. Trace the flow of air into and out of the lungs.
3. Explain how Boyle’s law relates to the changing intrapleural and alveolar air pressures and volumes during respiration.
4. Define various pulmonary volumes.

Introduction

The respiratory system plays a vital role in carrying air to and from the lungs. Air enters through the nose or mouth and passes through the pharynx and larynx before traveling down the trachea and bronchial tree to reach the lungs. The process of inhalation occurs when pressure within the lungs decreases below atmospheric pressure, facilitating airflow. This decrease in pressure is achieved by increasing the volume of the thoracic cavity. The lungs, encased within closed pleural cavities, move in tandem with the chest wall. The pleural membrane, a double-layered structure, protects each lung. Lung function can be assessed through spirometry, a technique that measures pulmonary volumes. Let’s dive deeper into the fascinating anatomy and mechanics of this essential system!
