The body of a typical 70 kg adult human contains ~1 kg of calcium, almost all of it in the form of bone mineral. Under normal conditions, a person loses ~175 mg of calcium per day in the urine and replaces a similar quantity of calcium by absorption through the gut. If a person suddenly stopped consuming any calcium at all but the rate of urinary calcium loss remained the same, how long would it take for the body calcium stores to decrease by 5%?

The normal level of calcium in blood ranges from 8.5 to 10.2 mg/dL. It must be tightly controlled. Mention the hormones that participate in the control of calcium level and explain the role of these hormones in the process of calcium homeostasis.
Gout—a condition that results in joint swelling and pain—is caused by the formation of sodium urate (NaC5H3N4O3) crystals within tendons, cartilage, and ligaments. Sodium urate precipitates out of blood plasma when uric acid levels become abnormally high. This sometimes happens as a result of eating too many rich foods and consuming too much alcohol, which is why gout is sometimes referred to as the “disease of kings.” If the sodium concentration in blood plasma is 0.140 M, and Ksp for sodium urate is 5.76 * 10 - 8, what minimum concentration of urate would result in precipitation?

Hiro is a 46-year-old male who has recently acquired severe food poisoning, which caused 72 hours of frequent vomiting and diarrhea. The third day after his symptoms began, Hiro experienced heart palpitations and confusion. He had trouble answering simple questions and felt disoriented. His care team was concerned about these new symptoms and decided to perform a urinalysis and several blood tests to determine the cause. These are Hiro’s results: Blood Calcium Level: 4.6 mEq/L Blood Sodium Level: 140 mEq/L Blood Potassium Level: 2.9 mEq/L Urine Specific Gravity: 1.020 Hiro’s electrolyte imbalance is caused by vomiting and diarrhea. Which of the following could also cause his condition? (Select all that apply.) Excessive laxative use Diuretics Excess aldosterone secretion Diabetic ketoacidosis Folic acid supplements
