Video Summary
The human body has a narrow range of pH that is considered physiologically normal, which is between 7.37 and 7.42. The body uses buffers to maintain pH within this range. Buffers are substances that help maintain the pH of a solution within a specific range. They work by absorbing or releasing hydrogen ions (H+) to counteract changes in pH. ate, phosphate, and plasma proteins, and the most important buffers within cells are proteins like hemoglobin, and organic phosphates, like ATP.
