Step by step
Solved in 2 steps
- Drugs that increase urine flow (diuretic drugs) are often employed in the treatment of hypertension (high blood pressure) or other disease states. Three physiological categories of such drugs are ones that (i) function as loop diuretics, (ii) inhibit the action of aldosterone, and (iii) block Na+ channels in the collecting ducts. Explain why each of these categories would be expected to increase Na+ excretion and urine flow.If a patient’s urinary plasma flow is 600ml/min and hematocrit is 50%, what will be his urine blood flow ?Urine creatinine: 180 mg/dL . Plasma creatinine: 2.3 mg/dL . Urine output: 1.6 mL/mi Creatinine Clearance (C) = (Urine Creatinine × Urine Flow Rate) / Plasma Creatinine What is C
- Give the 4 factors affecting the urine volume in physiological system. Explain how each factor affects the volume of urine.Which of the following is a physiologic response of the kidneys to decreased plasma volume? decreased sodium reabsorption O increased antinatriuretic protein secretion dilatation of the afferent renal arterioles increased tubular permeability to waterA person ate a bag of salty potato chips but did not drink any fluids. What is the effect of this on his urine concentration and the rate of urine production. Explain the mechanisms involved.
- Glomerular filtration is affected by forces that oppose and promote filtration. What are these forces and explain the theory behind net filtration pressure?Describe how each of the following works to regulate reabsorption and secretion, so as to affect urine volume and composition: renin-angiotensin system, aldosterone, antidiuretic hormone, and natriuretic peptidesis specific gravity (of urine) directly realted to urine output volume? like as one decreases the other one does as well or am i off?
- Describe how each of the following works to regulate reabsorption and secretion, so as to affect urine volume and composition: renin-angiotensin system, aldosterone and antidiuretic hormone.What is the relationship between electrolytes and urine pH? What physiological mechanisms facilitate this relationship?Please explain why fluid intake can decrease urine specific density
