1. Hemocytoblasts
2. Progenitor cells to RBCs, platelets, and granulocytes
3. Groups of pacemaker cells outside the SA node that cause a premature and irregular heartbeat
4. The brain's arteries rupture/burst, so excess blood spills and affects the brain & it's tissues (aneurysm)

Decreased pH (increased hydrogen) directly causes lower hemoglobin affinity for oxygen and hemoglobin binds tighter to oxygen at high pH than low pH. Carbonic anhydride also converts gaseous carbon dioxide to carbonic acid that releases a hydrogen ion that reduces pH of blood.
So from that you can deduct that decreased oxygen/abundance of carbon dioxide > pH decrease
Abundant oxygen/decreased car ion dioxide > pH increase

A lot more in depth than I was looking for haha, but nonetheless good job! Your turn.

Hi sorry for the interruption in the question marathon, but can somebody explain which out of the two, fetal hemoglobin or myoglobin, have a higher affinity for oxygen and why?
