The Respiratory System

Mr. Anderson's podcast explores the respiratory system, focusing on its function of oxygen intake and carbon dioxide expulsion. He discusses the challenges of high altitudes, like Mount Everest, and how animals adapt to different environments. The podcast compares fish gills and human lungs, explaining countercurrent exchange and the structure of human lungs, including alveoli and the role of surfactants. Breathing mechanics are explained through diaphragm function, and the exchange of gases is detailed, highlighting hemoglobin's role in oxygen transport and bicarbonate in carbon dioxide removal.
