This video discusses: Gas pressure gradient across respiratory membrane Causes of the pressure gradient Capillary diffusion dynamics Adaptation during the exercise

This video discusses: Structure of the Hemoglobin Hb dissociation curve Factors affecting the dissociation curve Oxygen buffering by Hb

This video discusses: Total volume of the carbon dioxide transport to the lungs Three forms of the carbon dioxide transport Chloride shift Carbonic anhydrase Carbon dioxide pressure gradients in the tissue and lungs

This video discusses Bohr Effect Increased carbon dioxide pressure in the tissue helps unload oxygen in the tissues. This is opposite to the Haldene effect where increased oxygen pressure helps unload carbon dioxide in the lungs.

This video discusses: Alveolar ventilation Blood flow through lungs Calculating the ratio Evaluating the V/Q ratio Generalizations

Dr. Mobeen discusses oxygen pressure changes to help load or unload carbon dioxide from the hemoglobin.

Oxygen pressure changes are critical for CO2 movement in and out of the body. 

In lungs, we have more oxygen pressure which favors unloading of the carbon dioxide. This will help carbon dioxide eject from the body.

On the other hands in the peripheral tissues oxygen pressure is less. This allows carbon dioxide to be loaded on to the hemoglobin and move away from the tissue.

This video presents the lung function tests.

This video discusses: Control of respiration by a) Chemoreceptors, both central and peripheral. b) Neuronal control c) Respiratory rhythm d) Nerves involved in the respiratory control e) Effect of carbon dioxide and oxygen pressure changes on breathing rate and rhythm
