The renal pelvis 1 of 34 what is the order of arteries from the renal arteries to the glomeruli? Segmental, interlobular, arcuate and cortical radiate 2 of 34 What is the name of the tall cells in the DCT which either serve as baroreceptors or chemoreceptors? Macula densa 3 of 34 What provides the blood supply to the DCT? Peritubular capillaries 4 of 34 What is the renal fascia? Dense fibrous layer which anchors the kidney to surrounding structures 5 of 34 What makes up the juxtaglomerular complex? the DCT and afferent arteriole 6 of 34 What is the function of the juxtaglomerular complex? Functions as an endocrine organ and produces EPO and the enzyme renin 7 of 34 Dangerously low GFR can be caused by what? Shock, dehydration, haemorrhage 8 of 34 What causes the release of renin from the juxtaglomerular complex? decrease in blood volume, decrease in blood pressure and obstruction of blood flow to kidneys 9 of 34 What happens when theres a reductio in GFR? Renin is released 10 of 34 For a person with normal blood pressure what is the GFR? 125ml/min 11 of 34 What are the cells found between adjacent capillaries which can alter the diameter of capillaries to adjust blood flow? Mesangial cells 12 of 34 What is colloid osmotic pressure? Osmotic pressure resulting from the amount of suspended proteins in the blood 13 of 34 At what pressure does filtration stop as the net hydrostatic pressure is 0mmhg? 40mmhg 14 of 34 What hormone produced in the heart increases GFR? Natriuretic peptides 15 of 34 What are the opposing forces at the glomerulus? Capsular hydrostatic pressure and blood osmotic pressure 16 of 34 What process is secretion of hydrogen in the PCT through? Counter transport 17 of 34 Where is the majority of water reabsorbed? Proximal convoluted tubule 18 of 34 What is the region of the nephron containing interrelated cells and associated with pH balance? The collecting duct 19 of 34 What could cause a large amount of dilute urine often? Absence of ADH 20 of 34 What hormone promotes calcium reabsorption? Parathyroid protein 21 of 34 What does ADH do? Promotes water reabsorption at the kidneys 22 of 34 What is the value for total water losses and gains every day? 2500mL 23 of 34 What aldosterone-sensitive portions of the DCT and collecting duct allow for exchange of? Sodium for potassium 24 of 34 What will someone who is drowning experience? Acute respiratory acidosis 25 of 34 What is Tm in reference to reabsorption in the kidneys? Transport maximum- Number of available carrier proteins in renal tubules 26 of 34 Which part of the nephron does aldosterone control the reabsorption of sodium ions? Distal convoluted tubule and the collecting duct 27 of 34 Where in the nephron is loss of water, Na+ and K+ regulated? The nephron loop and collecting duct 28 of 34 What is the effect of aldosterone on DCT and collecting system? Conservation of sodium and water 29 of 34 What counter transport is found in the renal tubules? Sodium for hydrogen 30 of 34 What can occur as a result of prolonged aldosterone stimulation? Hypokalemia 31 of 34 Where does the most secretion of K+ and H+ into the tubular fluid take place? The distal convoluted tubule 32 of 34 Which part of the nephron is under the stimulation of aldosterone and ADH? Distal convoluted tubule 33 of 34 What is the name of the plasma concentration at which a substance begins to appear in the urine? The renal threshold 34 of 34
