060 Hemoglobin and the Oxygen-Dissociation Curve

The video, presented by Leslie Samuel, explores hemoglobin and the oxygen dissociation curve. It begins with an overview of the respiratory system, detailing how blood circulates through the heart and lungs. The role of red blood cells in oxygen transport is explained, focusing on hemoglobin's structure and function. The video describes how hemoglobin binds oxygen, causing conformational changes that facilitate further binding. This process is illustrated by the oxygen dissociation curve, which shows the non-linear relationship between oxygen pressure and hemoglobin saturation. The video concludes with an invitation to explore more resources on the website.
