Explanation The blood transports oxygen and carbon dioxide through continuous interchange of ions while transporting. So, there is a paradoxical relationship between oxygen and carbon dioxide whenever a diver dives into the water. This happens because of varying levels of partial pressure of gases, carbon dioxide and oxygen in the pulmonary capillaries denoted as PA CO2 and PA O2, respectively. As the diver goes down or descends, the O 2 (oxygen) tends to move into the blood contained in the pulmonary capillary from the alveoli. This systemic regulation helps tissue metabolism by providing more O 2 . This regulation becomes a disadvantage when the diver dives back to the surface leading to the expansion of lungs and decrease in the levels of PA O2 ...
