add example. 1  en The Amur Leopard (from the name of the river flowing at the border between Russia and China, or Far Eastern leopard, Panthera pardus orientalis) is quite certainly the rarest and most endangered big cat in the world because of a wild population of only 30 to 35 individuals [ 1 ].
Rebreathing resulted in acidosis because the pH value began to dip below the normal range between 20 and 30 secods--as soon as it went below 7.35. Acidosis is the result of impaired respiration (hypoventilation)that leads to the accumulation of too much carbon dioxide in the blood.
The lungs and kidneys are the major organs involved in regulating blood pH. 1  The lungs flush acid out of the body by exhaling CO 2. 2  Raising and lowering the respiratory rate alters the amount of CO 2 that is breathed out, and this can affect blood pH within minutes. Raising and lowering the respiratory rate alters the amount of CO 2 that is breathed out, and this can affect blood pH within minutes. 2  The kidneys excrete acids in the urine, and they regulate the concentration of bicarbonate (HCO 3 - , a base) in blood.
