Question

In living things, most chemical reactions occur near pH 7, and changes in pH do not normally occur. Describe how buffers maintain a pH of 7 in the human body.

Answer 1

Buffers usually consist of a weak acid and its conjugate base; this enables them to readily absorb excess H+ or OH–, keeping the system's pH within a narrow range. Maintaining a constant blood pH is critical to a person's well-being.

Step-by-step explanation:

Answer 2

3 systems in the human body work together to regulate the ph. Acid base balance, chemical buffer like bicarbonate,respiratory, lungs regulate the co2 in the body and the urinary system keep the body at about 7.3, only a very small deviation is allowed, 7.5. any higher the person goes through acidosis, which is life threatening.
