In this physiology lecture, Professor Zach Murphy explains the process of Internal Respiration, focusing on how oxygen and carbon dioxide are exchanged between systemic capillaries and the body’s tissues at the cellular level. We begin by reviewing the role of partial pressure gradients that drive oxygen from the blood into tissues and carbon dioxide from tissues into the blood. You’ll learn how oxygen delivery is affected by capillary perfusion, oxygen demand, and the local metabolic environment, including temperature, pH, and carbon dioxide concentration. The lecture highlights how these factors shift the oxyhemoglobin dissociation curve to the right (Bohr effect), promoting oxygen unloading during high metabolic activity. We also explore how carbon dioxide is transported back to the lungs via dissolved CO₂, carbaminohemoglobin, and bicarbonate (HCO₃⁻) through the chloride shift mechanism.
