Acid-Base Balance
Normal blood pH ranges from 7.3-7.4. Decreased pH is termed acidemia and is caused by an increase in the concentration of hydrogen ions ([H+]). Increased blood pH is termed alkalemia and is caused by a decrease in the [H+]. The buffer systems that maintain this pH balance are bicarbonate…

the bicarbonate from building up in the red blood cells, which would slow down or stop the reversible conversion of CO. 2 to HCO 3-. Facilitated diffusion. occurs in the movement of CO. 2 across the respiratory surfaces as bicarbonate (HCO 3-) diffuses out of the red blood cells and into the epithelium where it is converted back to CO 2.

It only reflects changes in the bicarbonate buffer system, the most important of the blood buffers. In Calgary the normal range is 20 - 24 . If the bicarbonate is < 20 = acidemia. If the bicarbonate is >24 = alkalemia. B.E/B.D. the Base Excess or Base Deficit - reflects the change in all blood buffering systems.

The red blood cell is in the right atria, meaning it is currently deoxygenated and in the pulmonary circulation circuit. At this time the hemoglobin is not binding O2, but the red blood cell is carrying CO2waste, in the form of bicarbonate, to the lungs to be exhaled.

Alkalosis - blood pH above 7.45. Alkalosis causes excitability of nervous tissue - spasms, convulsions & death. Respiratory acidosis and respiratory alkalosis are primary disorders of blood PCO2 (Table 27.4) Metabolic acidosis and metabolic alkalosis are primary disorders of bicarbonate concentration
homeostasis and acid base balance

ACIDS AND BASES IN THE HUMAN BODY
The body uses different mechanisms to control the blood's acid-base balance such as the release of CO2 from the lungs, adjusted kidney function for excretion of substances and controlled buffering of blood via concentrations of the bicarbonate ion. 6. Acidosis and alkalosis. are the two abnormalities of …
