How to Understand the hemoglobin & its role in the body

An in-depth explanation of the structure of the hemoglobin molecule, the process by which it binds with the oxygen in the lungs, how it dumps the same oxygen molecule at the appropriate location in the body and how carbon-dioxide gets attached to the hemoglobin molecule are the topics which the narrator in this video explains with diagrams and a few equations. To clearly understand the concepts, cursory knowledge of the following topics is required: * Equilibrium chemical reactions, * The concept of diffusion across a membrane, * Protein structures, * Saturation point and pressure, * and 2D graph interpretation. All these concepts however, are taught in school/college level science courses and are easy to grasp.
