Due Date: Dec. 8

Using the pictures in the Urinary System chapter of your textbook as a reference, locate the following parts on the preserved pig kidney and kidney models in lab:

fibrous capsule
renal column
renal pelvis
major and minor calyx (kidney models only)
renal papilla
renal cortex
renal pyramid
renal medulla
ureter

Locate the following microscopic structures on the large flat model depicting the histology of the nephron:

renal corpuscle
glomerulus
Bowman's (glomerular) capsule
proximal convoluted tubule (PCT)
loop of Henle (ascending, thin and descending limbs)
distal convoluted tubule (DCT)
collecting duct
afferent arteriole
efferent arteriole
peritubular capillaries
vasa recta

1.  In which part of the nephron does filtration of the blood occur?
 

2.  Name two filterable components of the blood that become part of the filtrate:

3.  Name two non-filterable components of the blood that do not end up in the filtrate because they are too large:

4.  In what segment of the nephron does most of the process of reabsorption occur?

5.  In what segment of the nephron does most of the process of secretion occur?
