Topic 2. Exercise Physiology

Physiology is the study of how the body functions. This topic explores the efficiency of these systems during exercise.

2.1 Ventilatory System

The structure and function of the ventilatory system supports life. The health of our ventilatory system can be measured in a variety of ways that change with technology. The overall best bet is a healthy lifestyle that ensures the oxygen transport system is functioning at its optimum levels.

2.1.1 - List the principal structures of the ventilatory system
2.1.2 - Outline the functions of the conducting airways
2.1.3 - Define the terms PULMONARY VENTILATION, TOTAL LUNG CAPACITY, TIDAL VOLUME, EXPIRATORY RESERVE VOLUME, INSPIRATORY RESERVE VOLUME and RESIDUAL VOLUME.
2.1.4 - Explain the mechanics of ventilation in the human lung.
2.1.5 - Describe the nervous and chemical control of ventilation during exercise.
2.1.6 - Outline the role of hemoglobin in oxygen transportation.
2.1.7 - Explain the process of gaseous exchange at the alveoli.
