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.
Blood pH is tightly regulated by a system of buffers that continuously maintain it in a normal range of 7.35 to 7.45 (slightly alkaline). Blood pH drop below 7 can lead to a coma and even death due to severe acidosis. This causes depression of the central nervous system.High blood pH (above 7.45) is called alkalosis.ence, breathing directly affects blood pH. In its turn, blood pH is tightly monitored within a very narrow range (from about 7.3 to 7.5) by the group of nerve cells located in the medulla oblongata in order to have normal-body biochemistry.
