Scenario: DW is a 65-year-old, 135 kg male who visited his primary care physician for a routine examination. His blood pressure was 158/100 mmHg and his heart rate was 71 bpm. Stroke volume and cardiac output were normal. Serum renin levels were in the normal range. A chest x-ray revealed left ventricular hypertrophy. Other clinical findings were unremarkable.
For this problem, pharmacologic therapies include diuretics, ACE inhibitors, beta-adrenergic receptor antagonists, and vasodilators. Explain the physiological effects on the cardiovascular system for each of these 4 classes of drugs and why these could be helpful.

Case presentation: Mrs. Lianne Thomson, a Caucasian female of 45 years old with a BMI of 26, presents to the office with dull ache pain and tingling over the right hand, wrist and elbow. She is a full-time massage therapist with a career of 15 years and her pain is gradually getting worse during the last month. Symptoms started about two months ago apparently during her long shifts while she is working. This pain is rated as a 5 or 6 out of 10 and increases in intensity specially after a long day at work. Patient have not experienced this type of pain before and there a remarkable past medical, social and family history.

“My Brother Calls Me ‘Bug Eyes’”: A Case Study on the Endocrine System
Nineteen-year-old Krista waited impatiently as Dr. Weisman scribbled in his chart. She hoped he was scribbling an explanation of what was wrong with her. She was tired of not feeling like herself and tired of being so stressed about it. She was particularly tired of how her eyes seemed to bulge outward, so much that her 10-year-old brother had started calling her “Bug Eyes.”
Dr. Weisman finally put down his pen and looked at Krista. “Well, your blood pressure and pulse are elevated. You’ve lost weight without trying, you have difficulty sleeping, you perspire more than usual and you’ve had continuing bouts of diarrhea. Those things, combined with the swelling in the front of your neck, suggest that you may be suffering from more than the stress of college life. I think we need to run some blood tests to check your thyroid function.”
Krista blinked in surprise. “All of those things can be caused by a problem with my thyroid? Even the way my eyes look?”
Dr. Weisman nodded. “Your thyroid secretes several hormones that have widespread and varied effects. The protrusion of your eyes is a condition called exophthalmos – it is an inflammatory response to abnormal levels of thyroid hormones. The fact that you have this condition in addition to your other symptoms makes me fairly certain this is a thyroid problem.”
Krista hoped Dr. Weisman was right. Having a medical explanation for her symptoms would mean that she wasn’t losing her mind. Several days later, Krista met again with Dr. Weisman.
“Let’s talk about your test results,” he said. “Your thyroid hormone levels are elevated, but your level of thyroid-stimulating hormone (TSH) is lower than it should be. Those results suggest that you probably have Graves’ disease, which means that your thyroid is overactive. But there’s good news too—this is a condition that we can treat relatively easily.”
Krista felt a twinge of relief at the doctor’s words, but a flurry of questions poured out of her mouth. “What made my thyroid go crazy? And what is TSH? If it’s a thyroid hormone, why is it low instead of high like everything else? And what kind of treatment do I need? Will it fix my thyroid? Will I…”
Dr. Weisman laughed and held up his hand to stop the barrage of questions. “Hold on, Krista. I’ll explain everything, and with the right treatment, your brother may not be able to call you ‘Bug Eyes’ much longer.”

None of these are correct |
filtration in the many glomerular capsules is somewhat constant except for certain conditions. Which of the following may alter GFR?
excess body fluids will decrease GFR |
||
low body volume will increase GFR |
||
excessive body fluid will increase GFR |
||
Secretion of Renin will have no effect on GFR |
||
Atrial natriuretic peptide, when secreted, will stimulate sodium retention by the kidneys. |
||
The secretion of Angiotensin II will cause vasodilation and decreased thirst. |
Which choice represents an accurate route for urine?
minor calyx to major calyx to nephron |
||
major calyx to the renal pyramid to the bladder |
||
major calyx to the renal pelvis to the ureter |
||
nephron to renal sinus to renal column |
Why does aldosterone secretion help during periods of dehydration?
Aldosterone induces sodium reabsorption which increases water retention |
||
Aldosterone stimulates the collecting ducts to be impermeable to water, increasing urine production |
||
Aldosterone blocks the action of Renin |
||
Aldosterone causes angiotensinogen to be neutralized. |
||
Two of these choices are correct |

Why would sodium reabsorption help maintain body fluid volume?
Sodium weighs a lot so it helps make us feel full. |
||
Where salt goes, water follows. |
||
Sodium is never reabsorbed in the nephron. |
||
Sodium is a negative ion. |
The loop of the nephron is primarily located in which 'layer' of the kidney?
