Islets of langerhans 7 of 27 how does insulin mainly decrease blood glucose increasing the permeability of body cells to glucose 8 of 27 what is the process that converts glucose to glycogen? glycogenesis 9 of 27 what is glycogenesis in response to? an increase in blood glucose 10 of 27 what is the name of the process which converts glucose into fatty acids? lipogenesis 11 of 27 what is lipogenesis in response to? an increase in blood glucose 12 of 27 what is the name of the process which converts non-carbohydrate sources into glucose in the liver? gluconeogenesis 13 of 27 what is gluconeogenesis in response to? a decrease in blood glucose 14 of 27 what is the name for the breakdown of lipids and triglycerides into glucose in the adipose tissue lipolysis 15 of 27 what part of the body detects temperature changes and determines a core temperature receptors in the hypothalamus 16 of 27 what is stimulated during thermoregulation by the hypothalamus after it detects an increase in temperature Heat Conservation Centre 17 of 27 what is stimulated during thermoregulation by the hypothalamus after it is stimulated by a decrease in temperature Heat Loss Centre 18 of 27 what is urea? A poisonous chemical made by the liver, that is transported to the kidneys and then excreted 19 of 27 what carries urine from the kidneys to the bladder ureter 20 of 27 what is the net effect of ultrafiltration fluid moves out of the capillary and into the lumen of the renal capsule 21 of 27 What is filtered into the lumen of the renal capsule during ultrafiltration SUMGAV 22 of 27 how is pressure created during ultrafiltration the dramatic change in diameter from the afferent atriole and the efferent atriole 23 of 27 where does selective reabsorption occur? proximal convoluted tubule 24 of 27 where does selective reabsorbtion go to back into the blood 25 of 27 during selective reabsoprtion, where is water absrobed into? collecting duct 26 of 27 during selective reabsoprtion where is glucose absorbed into proximal tubule 27 of 27
