BIOD 152- Module 7 Exam Updated 2024What are the 2 methods of renal control mechanism? - -H+ secretion-conversion of bicarbonateWhen and where does H+ secretion occur? - -in response to pH of the extracellular fluid-secretes through renal filtrateExplain the conversion of bicarbonate in the renal control mechanism - -bicarbonate isreplenished in the plasma by reclaiming it from the rental filtrateHow is the renal control mechanism used during alkalosis? - renal collecting ductintercalated cells can secrete bicarbonate while simultaneously recovering H+ to lower thepH of the bloodNormal blood serum levels - Normal pH = 7.35-7.45Normal PCO2 = 35-45 mm (pressure of carbon dioxide)Normal HCO3- = 22-26 mEq/L (bicarbonate)When is acidosis and alkalosis disorders metabolic? - isn't caused the the pressure of CO2in the bloodWhen is acidosis and alkalosis disorders respiratory? - whether the cause is higher or lowerCO2 pressure in the bloodWhat can happen if there is severe acidosis? below 7 pH - central nervous system ismarkedly depressed causing:-coma-imminent deathWhat can happen if there is severe alkalosis? above 7.8 pH - nervous system is markedlyexcited causing:-extreme nervousness-muscle contractionPreview Mode
