During the transport of carbon dioxide, blood does not become acidic due to:

Explanation

Option A: Although much COz is carried-in blood, blood does not become acidic. It is due to CO, transport and the buffering action of blood. The main buffer present in the blood is bicarbonate (which is formed during CO, transport in the blood).Option B: Neutralization of H/CO3 by NaHCO3, is not correct because it suggests the use of an external source of bicarbonate ions to neutralize the hydrogen ions produced during the transport of CO2, which is not the case. While sodium bicarbonate (NaHCO3) is involved in the regulation of acid-base balance in the body, it is not directly involved in the transport of CO2.Option C: Absorption by leukocytes, is not correct because leukocytes (white blood cells) do not play a significant role in the transport of CO2 in the bloodstream.Option D: Non-accumulation, is not correct because CO2 is indeed accumulating in the blood during transport, and it is the role of buffering systems to prevent the accumulation of hydrogen ions that would lead to acidosis.
