ANATOMY & PHYSIOLOGY II
System Assignment
Urinary System
The purpose of this assignment is to ensure that you are working diligently to keep up
with the material and to give you practice both researching answers and answering
questions specifically and succinctly.
To receive credit for this assignment, your answers must be in your own words, and:
❏ well-written, with terms correctly spelled.
❏ NOT copied from any course handouts;
❏ NOT be copied from your or any other textbook (with the exception of
definitions);
❏ NOT be identical to another student’s answers; and
❏ NOT be dictated by academic support services in the ARC.
The due date for this assignment will be announced in class.

1. Definitions. Provide a simple, concise definition for the following terms (1 pt each):
hyperglycemia
nephron
osmolarity
ureter
juxtaglomerular apparatus (JGA)
filtrate
glomerular filtration rate (GFR)
renal pelvis
1
A
B
C
D
E
F
G
H
2. Matching. Match the labels on the figure with the terms below (2 pts each).
capsule
renal column
cortex
renal pelvis
major calyx
pyramid
minor calyx
ureter
3. What is the function of the ureter? (1 pt)
4. What is the function of the urethra? (1 pt)
2
5. Fill in the blank spaces to complete the concept map (8 pts).
Interlobar
artery
6. Once your concept map is complete, color the boxes as described below (3 pts):
 Color the boxes that “contain” oxygenated blood RED.
 Color the boxes that “contain” deoxygenated blood BLUE. (To be technically
correct, one of the boxes can be half red/half blue.)
 Color the boxes that “contain” filtrate/urine YELLOW.

7. The epithelial cells that line the renal tubules are highly specialized to fit their
important function in either secretion or absorption. In the table below, briefly summarize
both the structural and the functional aspects of these cells (4 pts).
Cell type:

Function
PCT cells

Loop of
Henle cells

DCT cells

Collecting
duct cells

*Hint: This column can be answered with a nice, well-labeled drawing!

As blood passes into the glomerulus, it is subjected to an increase in hydrostatic
pressure that is crucial for filtrate formation.
8. What is hydrostatic pressure? (1 pt)
9. Explain how this increase in pressure is achieved (2 pts).
10. When the filtrate is produced, what types of molecules can pass into the renal
tubule? (1 pt)
11. What types of things can’t/shouldn’t (under normal circumstances) pass from the
blood supply to the filtrate? (1 pt)
12. Describe the organization and function(s) of the juxtaglomerular apparatus. In your
answer, list the two important monitoring cells found in the JGA and include their jobs in
filtrate formation (3 pts).
5
The diagram below illustrates the negative feedback relationship that occurs between
the kidney and the hypothalamic/pituitary axis during the regulation of water balance in
the blood. Note: + indicates a stimulatory effect and – indicates an inhibitory effect.
13. Use the list of terms below to fill in the blanks in the diagram. (Note that two of the
boxes should get two terms each; they’re numbered 1 and 2) (4 pts).
Rising blood osmolarity
Falling blood osmolarity
Water reabsorption
Increases porosity
Rising blood volume
Falling blood volume
ADH
14. When you are done, label the following on the diagram (1 pt):
 collecting duct
 hypothalamus
 posterior pituitary
