Case
Studies Tasks:
Revisit Jane (One Last Time): Jane was riding her horse on a warm
sunny day (101 degrees Fahrenheit) when suddenly her horse stopped
and reared up in the air. Jane was not prepared for this and fell
hard backwards into the ground. As she hit the ground Jane's leg
was gashed open by a large, sharp boulder that she fell next to.
Jane began to bleed severely. Jane's body spends the next couple
hours physiologically compensating for her blood loss. From what we
have learned so far this quarter, we know that her blood loss
causes blood volume, blood pressure, and cardiac output to plummet.
Through a Urinary lens, but including other systems: Create a
diagram to explain how Jane's body is physiologically responding to
the blood loss in order to restore to homeostasis and how that will
affect urine production. Make sure to include the following:
Nephron
Collecting Duct
Aldosterone
ADH
Renin
Angiotensin II
Water
Sodium
ions
Glomerular Filtration Rate (and pressures affecting it)
Afferent arterioles
Efferent arterioles
Nitric
Oxide (NO)
ATP
Vasoconstriction/Vasodilation
Epinephrine
Adrenal Medulla
juxtaglomerular apparatus

Brian recently went to the doctor due to symptoms of headaches,
anxiety, vision impairment, and confusion. After performing some
diagnostic tests the Doctor received the following results in
regards to blood pH, pCO2. The Doctor also found this situation to
be chronic rather than acute. Based on the data below, provide the
diagnosis (Based on what you have covered in this unit) and create
a diagram that shows how the renal system would compensate to bring
the body back to normal. In your diagram, make sure to include at
least:
Renal
tubules, arterioles, bicarbonate buffer, H+ ions
ABGs:
pH -
7.30
pCO2 -
50 mmHg
HCO3-
- 28 mEq/L
