Step by step
Solved in 3 steps
- The following substances are normal constituents in urine. Determine their metabolic origins in the human body. Urea - Creatinine- Indican - Uric acid- 2.Why is analysis of urine important in the diagnosis of diseases?The presence of either protein or glucose in a urinalysis is abnormal, but these two molecules 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.which blood pH would cause the kidneys specifically the collecting ducts to excrete bicarbonate (HCO3-) into the blood? note: this works through the carbonic acid bicarbonate buffer system. Basic, acidic, or neutral.
- 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 helpGout—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?Describe the three processes involved in urine formation: filtration, secretion and reabsorption. Discuss the formula: E = F – R + S.
- Of the following solutes, which ones are least likely to be found in the urine of a healthy person: erythrocytes, glucose, sodium ions, and/or hydrogen ions? Explain why you normally wouldn’t expect to find this (these) solute(s) in the urine.Answer the following questions: a. Is glucose normally present in urine? In what condition can it be detected in urine? b. In the presence of positive result in Fehling's and Benedict's tests, how would you eliminate the reducing effect of uric acid and creatinine?Diabetes insipidus (DI) is a condition where the action of antidiuretic hormone (vasopressin) is inhibited. If normal urine concentration is 300 mOsm/L, what would you expect the urine concentration to be of a patient with DI?
- Use the following information to answer the next three questions. Component Plasma Glomerular Urine Filtrate urea 0.03 0.03 2.00 uric acid 0.004 0.004 0.05 glucose amino acids 0.10 0.10 0.00 0.05 0.05 0.00 salts 0.72 0.72 1.50 proteins Table 1: Composition of Plasma, Glomerular Filtrate, and Urine (g/100 mL fluid) of a Healthy Aduln 8.00 0.00 0.00 The two components listed above that are completely reabsorbed from the glomerular filtrate before it becomes urine are O proteins and amino acids. urea and glucose. O urea and uric acid. O glucose and amino acids.A urinalysis is a test that examines physical, chemical and microscopic aspects of urine. Examining urinary fluid can reveal much about the functioning of the body, as changes from the normal characteristics or appearance may reflect specific diseases. Currently, commercially-available chemical reagent sticks can be used to detect substances in urine. Of the following, which are substances that reagent sticks can test for? a. Substances produced by the body, and naturally found in urine. b. Substances produced by the body, but not usually present in urine. c. Substances not normally found in the body. d. a. and c. only e. a., b., and c.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.
