Many aquatic animals can withstand very long periods of hypoxia. Many aquatic animals respond to hypoxia by utilizing anaerobic mechanisms. Many animals adjust their respiratory and cardiovascular systems to maintain adequate supply of oxygen from hypoxic waters. Some fishes increase the ventilation rate of their gills so that more water flows and more oxygen can be absorbed. Similarly, ram ventilators open their mouths and swim so that water enters them and flows from gills.

Dear students, now we shall discuss hypoxia at high altitudes. As a result, the partial pressure of oxygen is also reduced in the environmental oxygen as well as in the blood oxygen level. Dear students, when partial pressure of oxygen is reduced, it stimulates the carotid and aortic body chemo receptors in mammals. As a result of this, lung ventilation rate increases so that more oxygen can be absorbed from the environment and less quantity of oxygen can be dealt with. But, there is a problem with this. When the ventilation rate increases, oxygen is more intended to be absorbed but with that, the carbon dioxide also loses in the excess of carbon dioxide. That results in a fall in the pH in the cerebrospinal fluid. Rather, it increases the pH of cerebrospinal fluid. Increase in pH of the cerebrospinal fluid causes a reduction in ventilation. So, this is counter-act of this factor. The hypoxia-induced high ventilation rate reduces due to the increase in pH level. If the hypoxic conditions are continuously maintained, then the animal acclimatizes. The blood pH and the cerebrospinal fluid pH of the CSF are maintained by excreting large quantities of bicarbonate. This acclimatization takes some time. In humans, it takes about a duration of one week.
