Biol 373 Units 4a and 4b: Renal Function
__ nephrons have deeper loops of Henle in the kidney's medulla with respect to __ nephrons - correct
answer ✔✔Juxtamedullary; cortical
Nephron - correct answer ✔✔The functional unit of the kidney
The medulla consists of - correct answer ✔✔Loop of Henle and collecting ducts
The cortex consists of - correct answer ✔✔Bowman's capsules, proximal and distal tubules
Filtration - correct answer ✔✔Movement of water or solutes from blood into tubules
Is filtration selective? - correct answer ✔✔Nope! Anything that can be filtered (is small enough to be in
other words) will be
Reabsorption - correct answer ✔✔Selective movement of water or solute back into the blood
Secretion - correct answer ✔✔Intentional removing of molecules from blood and adding to filtrate
Where does secretion occur? - correct answer ✔✔Proximal and Distal tubules
The renal corpuscle consists of which 2 components: - correct answer ✔✔glomerulus and Bowman's
capsule
Glomerulus - correct answer ✔✔Series of capillaries where filtration occurs
Filtration fraction - correct answer ✔✔% of total plasma volume that filters into tubule
, What are barriers to filtration? - correct answer ✔✔Glomerular capillar endothelium,
The basement membrane
Epithelium of Bowman's capsule
List the 3 types of capillaries - correct answer ✔✔Continuous
Fenestrated
Sinusoid
What does GFR stand for - correct answer ✔✔Glomerular filtration rate
Factors that influence GFR include: - correct answer ✔✔Net filtration pressure

Filtration coefficient
Myogenic response - correct answer ✔✔Intrinsic response of arteriolar smooth muscle to pressure
changes
Tubuloglomerular feedback - correct answer ✔✔Flow through tubule influence GFR
Macula densa - correct answer ✔✔Modified tubular epithelium
