question 32 of 41
what is the typical ph of biological fluids in humans, such as blood and extracellular fluid?
13.9
19.2
3.6
7.4

Explanation:

The typical pH of human blood and extracellular fluid is tightly regulated to be around 7.4, which is slightly alkaline. Values like 13.9 (strongly alkaline), 19.2 (invalid pH, as pH ranges 0-14), and 3.6 (acidic) do not match the normal physiological range.

Answer:

7.4
