Question

What are the major chemical buffer systems of the body?

A. The urinary and respiratory
B. The urinary and digestive
C. The bicarbonate, phosphate, and protein
D. The bicarbonate, nucleic acids, and protein
E. The bicarbonate, phosphate, and nitrate

Answer 1

The major chemical buffer systems of the body include the bicarbonate, phosphate, and protein buffers. These buffers help maintain the pH of the blood and surrounding cells in the body's tissues and extracellular fluid.

Step-by-step explanation:

The major chemical buffer systems of the body include the bicarbonate, phosphate, and protein buffers.

The bicarbonate buffer is the primary buffering system in the body's tissues and extracellular fluid, maintaining the pH of the blood and surrounding cells.

In addition to the bicarbonate buffer, proteins such as albumin and hemoglobin, as well as phosphates, also help maintain the pH of the biological system.
