chapter 19: Kidneys (summary)
What is the renal blood flow order? - correct answer-afferent arteriole - glomerulus - efferent
arteriole - peritubular capillaries
Fluid filters from the glomerulus into - correct answer-Bowman's capsule
after fluid enters the bowman capsules it flows through - correct answer-1. proximal tubule
2. loop of Henle
3. distal tubule
4. collecting duct
* then drains into renal pelvis
Urine flows through the ureters to the - correct answer-bladder
Filtration - correct answer-movement of fluid from plasma into bowman's capsule
reabsorption - correct answer-movement of filtered material from tubule to blood
Secretion - correct answer-movement of selected molecules from blood to tubules
amount of solute excreted - correct answer-amount filtered - amount reabsorbed + amount
secreted
* E= F-R+S
Bowman's capsule epithelium has special cells called - correct answer-podocytes that wrap
around the glomerular capillaries and create filtration slits
mesangial cells - correct answer-control blood pressure and filtration within glomerulus/ help
support glomerular capillaries
filtered solutes must first pass through - correct answer-glomerular capillaries endothelium -
basement membrane- finally through podocyte filtration slits before reaching the lumen of
Bowman's capsule
filtration allows most components of plasma to enter the tubule except ? - correct
answer-blood cells and almost all plasma proteins
Glomerular filtration rate (GFR) - correct answer-the amount of fluid that filters into
Bowman's capsule per unit time
what is the average GFR - correct answer-7.5 L/ hr
How can hydrostatic pressure in glomerular capillaries be altered? - correct answer-By
changing resistance in the afferent and efferent arterioles
