60- Bohr Effect

KYJ 60 - Bohr Effect.
 So I've been preparing for some new videos which I'll film in the next few weeks.  One is going to be on CO2, and how it is transported in blood.  Full of jargon.

One such term is the Bohr effect.
First know that 90% of CO2 is transported in plasma as bicarb (HCO3-), 5% is dissolved in plasma like bubbles in fizz drink.

In capillaries at the tissue end, blood is giving up
Oxygen and absorbing CO2.  It is transported to the lungs and CO2 is diffused off the blood and breathed out, and oxygen is diffused into blood, and transported back to tissues where the process repeats itself.

At that tissue end of respiration,  As co2 rises, blood pH and oxygen carriage falls. This is called the Bohr Effect.

The Bohr effect then shifts the oxyhaemoglobin curve to the right.
