a.
To determine: The amount of Ca2+ a person filters in a day.
Introduction: GFR (glomerular filtration rate) describes the amount of fluid that filters into Bowman’s capsule per unit time.
b.
To determine: The amount of Ca2+ a person must excrete to balance the Ca2+ level in the body.
Introduction: The total body Ca2+ is all the calcium in the body, which is distributed among three compartments: extracellular fluid, intracellular Ca2+, and extracellular matrix (bone).
c.
To determine: The percentage of filtered Ca2+ to be reabsorbed by the renal tubule.
Introduction: The Ca2+ loss from the body occurs primarily through the kidneys, with a small amount excreted in feces.

- Which of the following does not contribute to the process of filtration? (a) active transport by epithelial cells lining renal tubules (b) large surface area for filtration (c) low permeability of glomerular capillaries (d) high hydrostatic blood pressure in glomerular capillaries (e) podocytesarrow_forwardWhich of the following does not contribute to the high salt concentration in the interstitial fluid of the kidney medulla? (a) active transport of sodium from the upper part of the ascending limb (b) diffusion of salt from the ascending limb of the loop of Henle (c) reabsorption of salt from various regions of Bowmans capsule (d) counterflow of fluid through the two limbs of the loop of Henle (e) diffusion of urea out of the collecting ductarrow_forwardGiven: The concentration of glucose in the blood is 1 mg/mL. This person then decides to go for a brisk run, which doubles GFR. a. What effect will this have on the amount of inulin and glucose present in their urine? Why? (answer a )arrow_forward
- Table 3. Serum creatinine values at admission and after 12h Admission +12h SCR(mg/dL) 1.55 1.42 Using the “MDRD” (Modification of Diet in Renal Disease) equation for estimating glomerularfiltration, provided below, and the data available in the above table, calculate the patient's (a 34 year old white male) estimated glomerularfiltration rate (eGFR) at admission and 12h after admission.MDRD GFR Equation (mL/min/1.73 m2)= 175 × (Scr)-1.154 × (Age)-0.203 × (0.742 if female) × (1.212 if African American)Based on your calculated values, state whether LF’s function is normal or abnormal?Previous research suggests that patients with asthma have an increased risk for chronic kidneydisease, but the mechanisms underlying this increased risk are poorly understood. Propose one potential mechanism by which asthma might impair kidney function, and discuss how this dysfunction may impair thebody’s ability to respond to respiratory alkalosisarrow_forwardA 60-year-old woman with history of lung cancer is admitted for weakness and lethargy for 4 weeks. Her serum [Na*] is 120 mEq/L. She weighs 60 kg. Her serum osmolality is 250 mOsm/kg H2O with urine osmolality of 616 mOsm/kg H2O. The diagnosis of SIADH is made. What would be her serum [Na], if she receives 1 L of isotonic saline? A. 122 mEq/L B. 116 mEq/L C. 118 mEq/L D. 120 mEq/L E. 124 mEq/Larrow_forwardWhich of the following is TRUE concerning renal handling of potassium? a. A high potassium meal will cause enhanced basolateral uptake via sodium-potassium pumps b. Most potassium reabsorption occurs at the distal tubules c. Aldosterone enhances potassium reabsorption at the proximal tubule d. Potassium is not filtered, so urinary excretion of potassium will only occur by stimulating potassium secretion e. Decreased extracellular potassium concentration increases aldosterone production and thereby reduces potassium secretionarrow_forward
- A 30-year-old woman begins drinking excessive amounts because of increased thirst. She weighs 50 kg (110 lbs). She excretes approximately 8 L of dilute urine daily. Her serum sodium concentration is 147 mEq/L. Which of the following peptides will most likely relieve her thirst and decrease her daily volume of excreted urine? a. Angiotensin I b. Angiotensin II c. Bradykinin d. Desmopressin e. Oxytocin f. Substance Parrow_forwardA patient comes to your medical practice with complaints of low urine output (not peeing). You use inulin to calculate the glomerular filtration rate (GFR) using the following information: Plasma level (P – constant over 24 hours): 10 mg/mL inulin. Urine sample (U): 144 mg inulin/mL urine. Urine formation (V): 10 mL/min. Using the fromula GFR=V ✕ U/P, you calculate a GFR of ... A) 144mL/min.. B) 14400 mL/min. C) 144 min./mL. D) 144 g mannitol/min.arrow_forwardExplain the role each of the following plays in GFR regulation: Intrinsic control: Renal autoregulation Myogenic mechanism Tubuloglomerular feedback mechanism Extrinsic control: neural and hormonal mechanism Sympathetic nervous system controls Renin-Angiotensin-Aldosterone mechanismarrow_forward
- Consider a 24 y/o 90 Kg male who has a blood glucose of 500 mg/dl. Glomerular function is normal and urinary flow rate is 3.88 L /day. What is the best estimate of his urinary glucose concentration?arrow_forwardIf the rate of urine formation is 2 ml/min, the urine inulin concentration is 25 mg/ml, and the plasma inulin concentration 0.5 mg/ml, then the GFR is 6.25 mL/min None of the choices are correct. (c) 0.04 mL/min D) 100 mL/min E) more data is needed to calculate the GFRarrow_forwardAll of the following are true about glucose recovery from the tubule fluid, except (choose the incorrect statement): A. All filtered glucose is released in the PCT unless plasma glucose abnormally high B. It is reabsorbed by coupling with Na+ recovery via a sodium glucose cotransporter C. Glucose recovery is made possible by low intracellular Na+ concentrations created by the NaK pump D. The CD recovers any glucose that is not reabsorbed by the PCT nephron loop and DCT this is not and will not be gradedarrow_forward
