Objective68,70: Recognize How Chemical Buffers Interact to Protect the Body Against Lethal Changes of pH, Recognize How the Lungs and Kidneys Interact to Protect the Body Against Lethal Changes of pH

This page clearly explained to me how bicarbonate, phosphate, and protein buffers act to keep the our bodies in homeostasis by not letting our pH levels get out of whack. It showed me how the binding or releasing of H+ regulate and keep our pH levels at a constant level. It explains that blood pH stays very close to 7.4.
