NAME LAB TIME/DATE _ Endocrine System Physiology: Computer Simulation Metabolism The following questions refer to Activity 1: Determining Baseline Metabolic Rates. 1. Which rat had the fastest baseline metabolic rate? -------------------------The normal rat 2. Compare the baseline metabolic rates for the thyroidectomized rat and the normal rat and explain your results. The thyroidectomized rat had a lower baseline metabolic rate beause the removal of its thyroid gland prevented it

PhysioEX notes Autorhythmicity- heart’s ability to trigger its own contractions Phase O- a lot like depolarization in neuronal action potentials. Sodium channels open‚ increase of sodium INTO cell. Phase 1- sodium channels close‚ potassium channels close‚ decrease in potassium and sodium. Calcium channels open‚ increase of calcium into cell. Phase 2- Plateau phase‚ membrane still depolarized (contract). Potassium channels closed‚ L-type calcium channels stay open. Lasts 0.2 seconds/200

subjects that ingested the 6 gm. Of NaCl would increase over time in response to the increased osmolarity of the blood from all of the salt. Urine output would decrease and eventually the body would stabilize. Purpose: In this experiment‚ renal regulation of osmolarity will be demonstrated through the use of urinalysis. Materials and Methods: In this experiment‚ we assigned two groups. The first group was given 800ml of distilled to drink and the second was given 6mg of NaCl dissolved
