Gas Exchange in Humans | IGCSE , O Level Biology pptx
This comprehensive presentation on gas exchange in humans breaks down the critical processes that underpin respiration. It details how specialized gas exchange surfaces—primarily the alveoli—facilitate the rapid diffusion of oxygen into the bloodstream and the removal of carbon dioxide. The presentation explains the structure of the respiratory system, including the roles of the trachea, bronchi, and diaphragm in ventilation, and illustrates the differences in gas composition between inhaled and exhaled air using practical experiments.
