NUR 3125 Lecture Notes - Lecture 4: Lactic Acidosis, Nephron, Anion Gap
Document Summary
If the h+ are high in number, the ph is low (acidic). If the h+ are low in number, the ph is high (alkaline). The ph scale ranges from 0 to 14: Each number represents a factor of 10. If a solution moves from a ph of 6 to a ph of. 5, the h+ have increased 10 times. ph. Acids are formed as end products of protein, carbohydrate, and fat metabolism. To maintain the body"s normal ph (7. 35-7. 45) the h+ must be neutralized or excreted. The bones, lungs, and kidneys are the major organs involved in the regulation of acid and base balance. H2co3 (can be eliminated as co2 gas) [regulated by lung] co2 + h2o h2co3 hco3. Sulfuric, phosphoric, lactic and other organic acids. Eliminated by the renal tubules with the regulation of hco3. A buffer is a chemical that can bind excessive h+ or oh without a significant change in ph.
