Lab 14 The Urinary System BIO202L
Student Name: Hayley Proper
Access Code (located on the lid of your lab kit): AC-S1UH84M
Pre-Lab Questions
?What is the function of the ureter .1
.The function of the ureter is to carry urine from the kidneys to the bladder
.Compare and contrast the male and female urethra .2
While the female urethra carries only urine, the male urethra carries semen and urine
.but they both carry urine
.Describe the two layers of the kidneys .3
The first layer contains blood vessels and is called the renal cortex and the inner layer is
.called the renal medulla and looks like pyramids
Experiment 1: Kidney Filtration
Table 1: Solutions Present in Each Container Before 60 Minutes Submersion
Beaker Dialysis Tubing Solution
No it wasn’t Yes it was Congo Red
No it wasn’t Yes it was Yellow Food Coloring
Table 2: Solutions Present in Each Container After 60 Minutes Submersion
Beaker Dialysis Tubing Solution
No it wasn’t Yes it is Congo Red
Yes it was No it wasn’t Yellow Food Coloring
Post-Lab Questions
What specific part of the kidney does the dialysis tubing represent? What is this part’s .1”
”?function
The tubules and there function is to transport water and other things that travel through the
.kidneys
What does the yellow food coloring represent at the end of the experiment? What does the .2”
” ?Congo Red represent
.The yellow food coloring is urine and the congo red represents blood
, Lab 14 The Urinary System BIO202L
” ?Why is it important that the kidney filters the blood .3”
.Because without it we could get infections and if they buildup then it could lead to death
Experiment 2: Urinalysis
Table 3: Urine Test
Abnormal Normal Test
Acidic Urine (below 4.5) - Diabetes, starvation, dehydration,
.respiratory acidosis
7.5 - 4.5 pH
Alkaline Urine (above 7.5) - Kidney disease, kidney failure, urinary
tract infection, respiratory alkalosis.
.Glucose present (red or green color after test); diabetes mellitus None Glucose
.Protein present (violet color after test); kidney disease None Protein
.Yeast present (bubbles form after test); yeast infection in urinary tract None Yeast
Large amount of ketones present (sweet smell of urine); starvation,
prolonged vomiting, diabetes, hyperthyroidism, and other metabolic Little or
Ketones
None
.disorders
