As blood enters the lungs, a small amount of CO2 is carried by hemoglobin with the formula HbCO2.
HbH+ is carried by some hemoglobin.
2 in the pulmonary capillaries are carried as HCO3 in the blood.
Pushing this equation to the far right by breathing fast can cause you to stop breathing for a while, and pushing it to the left by not breathing is even more temporary, because breathing will soon resume due to the rise in H+.
The normal PO2 in the lungs is saturated with hemoglobin.
Each red blood cell is capable of carrying at least 1 billion molecules of oxygen, and each hemoglobin molecule contains four polypeptide chains.
The iron atom can bind to O2.
Carbon monoxide is an air pollutant that comes from incomplete combustion of natural gas, gasoline, kerosene, and wood and charcoal.
People can be unaware that they are breathing in CO.
When CO is in the bloodstream, it combines with the iron of hemoglobin 200 times more tightly than oxygen, and the result is death.
The reason that homes have CO detectors is because of this.
Blood entering the capillaries is a bright red color.
Cells continuously use up oxygen in their respirations, which leads to the lower PO2.
Carbon dioxide enters the blood from the tissues because the PCO2 of the fluid is higher than the blood.
Carbon dioxide is collected in fluid.
This reaction is sped up by carbonic anhydrase.
The release of H+ from this reaction could change the pH of the blood, which is highly undesirable, because cells need a normal pH in order to remain healthy.
The H+ is absorbed by the globin portions.
The reduced hemoglobin formula is HbH+.
The normal pH of the blood is maintained by HbH+.
The blood that leaves the capillaries is a dark maroon color.
