Detailed explanation-1: -The correct option is: a. Our blood and other bodily fluids might become too acidic or basic. For instance, the buffer in blood is the carbonic acid and bicarbonate buffer. Without this buffer, blood would not have its optimal pH value.
Detailed explanation-2: -Human blood contains a buffer of carbonic acid (H2CO3) and bicarbonate anion (HCO−3) in order to maintain blood pH between 7.35 and 7.45, as a value higher than 7.8 or lower than 6.8 can lead to death. In this buffer, hydronium and bicarbonate anion are in equilibrium with carbonic acid.
Detailed explanation-3: -A variety of buffering systems permits blood and other bodily fluids to maintain a narrow pH range, even in the face of perturbations. A buffer is a chemical system that prevents a radical change in fluid pH by dampening the change in hydrogen ion concentrations in the case of excess acid or base.
