MIC 211 Lecture Notes - Lecture 19: Hypoventilation, Metabolic Acidosis, Buffer Solution
Document Summary
Explain the terms; isotonic, hypertonic, hypotonic: hypertonic, more solute outside so cell shrinks because water leaves cells to the solute, hypotonic, more solute inside so cell swells and bursts because water goes in the cells to solute. Isotonic: total molar concentration of dissolved solutes is equal outside and inside. State the normal ph of the blood: 7. 38-7. 42. Describe why the ph of the venous blood is lower than the ph of the arterial blood. It carries waste products like co2 and acids produced by glucose burnt inside cells: both cause the ph to fall. Describe the sources of h+: carbonic acid and bicarbonate ion buffer system, o h2co3 hco3-+ h. Describe the ways each of the following are involved in keeping the [h+] where it should be (between 7. 35 and. It will react with water: breathing out will put co2 into the watery air.
