1. The Urinary and Reproductive Systems
Laboratory Twelve
The Urinary and Reproductive Systems
Your practicum grades will be posted inside the glassed-door cabinet. You can do self-stamped grade card to Ann or Cherryl, or stop by the lab after a week past your exam to obtain your grades if Cherryl is available.

2. Urinary Tract
Review detailed structure in kidney (male model in the lab)
Nephron: functional unit of kidney. There are 100s and 1000s of nephrons in this little section of kidney
renal corpuscle: There are two arterioles supplying and draining the glomerulus, the thicker one is the afferent arteriol and the thinner one is the efferent arteriol.
Study:
the dissected kidney…Go over different parts of the kidney: Renal cortex, renal medulla, renal pyramid with renal papilla
Nephron: functional unit of kidney…There are 100s and 1000s of nephrons in this little section of kidney, but only two of them are shown here
renal corpuscle: Go over renal corpuscle structures. There are two arterioles supplying and draining the glomerulus, the bigger one is the afferent arteriol

3. Male Reproductive System
Study both parasagittal and midsagittal view
Erectile bodies are much better seen in the purple model than the other model
Study both parasagittal (the cut section over the model) and midsagittal view (the cut section off the model)
Erectile bodies are much better in the purple model than the other model

4. Female Reproductive System
Study Uterus model as well
Parasagittal will not be used in practicum, but midsagittal view and the little model will be used. Ligament spensory can not be seen in the midsagittal section, but you can see it in the lab manual illustration.
Study Uterus model as well…Broad ligament and suspensory ligaments are viewed only on fig 13.9, p247.
Learn the external reproductive structures shown on fig 13.10, on the female pelvis model.

5. Follicle Development in Human Ovary
Each ovum develops before birth, but stops developing until menstrual cycle. some ova/follicles start maturing during menstrual cycle. The process of a follicle rupturing is called ovulation
Study the illustration on your lab manual for Primary, secondary, and graafian follicles. It’s better than the model in the lab.

6. Human Breast

7. Urinalysis (Measuring the Urine Composition)
Perform the following tests:
pH (acidity): average = 6
Clinistix (glucose): average = 0
Ketostix (ketones): average = 0
Hemastix (blood): average = 0
Albustix (Proteins): average = 0
Blistix or Ictotest (bilirubin): average = 0
These components are not normally seen in urine
Record your result on your handout
work in groups to find the associated disorder or disease for each abnormal result. Abnormal components of urine and associated disorders are found in your textbook

8. Bilirubin Test Cut off a square piece from the sheet
Put test square (mat) on paper towel
Place 10 drops urine on square (used pipette goes into regular trash)
Place 1 tablet on square. Do not touch the tablet
Add 1 drop of water onto tablet and wait 5sec
Add second drop onto tablet. It should spread over the tablet
Positive result if the square around the tablet gets dark; otherwise, it’s negative
