Document Summary
Describe ph, how it is calculated, and the normal ph of the body. Describe and understand the relationship between free hydrogen ion concentration, acid, Explain what a volatile acid is, what a nonvolatile acid is, and where they come from. List the three ways the body regulates against increases in free hydrogen ions (h+). Explain how buffers work to help maintain ph when the levels of h+ change. Explain how the respiratory system regulates the levels of volatile acids in the body. Describe how the kidneys regulate ph by excreting h+ and reabsorbing bicarbonate ions. Describe the types of alkalosis and acidosis and their causes. There is a high sensitivity to hydrogen ions in many body chemical reactions and inside. H+ ions can alter the shape of proteins to act as enzymes that speed up chemical reactions: therefore, any change in concentration of h+ will affect the activity of almost every cell.
