- Answer the question in 140 wordsA 28-year-old man has a fasting serum glucose concentration of 140 mg/dL and a glomerular filtration rate of 125 ml/min. The renal transport maximum for glucose in this patient is 300 mg/min. Which of the following best represents the rate of urinary glucose excretion (in mg/min) in this man? (A) 0 (B) 100 (C) 200 (D) 300 (E) 400Answer a, Anti-Diuretic Hormone (ADH) and Aldosterone both target kidney cells and increase water retention (keeping water in the blood, letting less go out with urine). ADH causes water retention directly- kidney cells let more water move from the urine back into the blood (the cells are a barrier between those two spaces). Aldosterone enhances water retention by causing more sodium to be retained, creating a stronger osmotic gradient. However, aldosterone also causes a loss of potassium to the urine for every sodium that is kept in the blood. a. Are these hormones both water-soluble or fat-soluble, or is there one of each? b. What chemical class does each belong to? c. Draw a picture hypothesizing how each might cause its target cells to have their effects. Don't look it up! You have all the information you need from the notes and explanation in this question to come up with a reasonable, logical hypothesis. d. If somebody has hyper-aldosteronism (secrete too much aldosterone,…
- Atrial Natriuretic Peptide helps to reduce overall blood pressure in a variety of ways. One way is by increasing Glomerular Filtration Rate. a. Why/how would increasing GFR cause decreased blood pressure? b. To increase GFR, would Atrial Natriuretic Peptide cause constriction or dilation of afferent arterioles at the kidneys? The efferent arterioles?a. A person ingests an ion-channel inhibitor, such that the ion channels present in the Loop of Henle are only able to pump at half their normal rate? b. What would this person notice about changes to their physiological filtration? (Answer a and b)Which of the following statements is true regarding Renal Function and the filtration of molecules? (this is not the same question as '48') 49. A. Large molecules like Glucose are not filtered into the renal tubules because Glucose is too big. B. Glucose molecules are ultimately secreted into the renal tubules; thát is why Glucose is found in the urine of a normal healthy person. C. Glucose molecules are filtered into the renal tubules but are rapidly reabsorbed; that is why very little glucose is found in the urine of a healthy person. D. Plasma Electrolytes are simply too big to be filtered into the renal tubules; that is why only a small concentration of extracellular electrolytes are is found in the urine of a healthy person.
- A 65-kg man is participating in a research study for which it is necessary to know the volumes of his body fluid compartments. To measure these volumes, the man is injected with 100 mci (millicurie) of H0 and 500 mg of mannitol. During a 2-hour equilibration period, he excretes 10% of the H,0 and 10% of the mannitol in his urine. Following equilibration, the concentration of H,0 in plasma is 0.213 mCi/100 ml and the concentration of mannitol is 3.2 mg/100 mL. • What is his total body water, his ECF volume, and his ICF volume? is the man's total body water appropriate for his weight?The presence of either protein or glucose in a urinalysis is abnormal but they end up in the urine for different reasons. For each of these molecules, briefly describe where in the urine production process (i.e., glomerular filtration, tubular reabsorption or tubular secretion) the problem occurs, and why it might happen. please helpch 25 act 9 please answer the questions in the picture attached
