Question

14) In a simulation of the filtratio the on membrane, which substance should be able to pass through B) leukocyte C) erythrocyte D) protein 15) Why can't a plasma protein move through the dialys is tubing of the simulated filtration A) opposite electrical charge B) shape incompatible with receptor C) too small D) too large 16) After the nephron loop. where in the renal tube would a urea molecule drain into next? A) proximal tubule B) distal tubule C) vasa recta D) glomerulus 17) In what part of the renal tube does most reabsorption of substances occu A) proximal tubule B) glomerular capsular space C) distal tubule D) nephron loop 18) Substance X was isolated in a urine sample but it is too big to pass through the glomerular filtration membrane. How is this possible? A) The glomerulus must be infected and hyper-permeable B) The kidney must be damaged. C) It was secreted later in the distal tubule. D) It isn't possible. There was a flaw in the urinalysis. 19) Substance Y is not present in the urine; however, it was originally filtered through the glomerulus. How is this possible? A) It was secreted in the distal tubule. B) It was resorbed in the proximal tubule. C) It was not filtered by the glomerulus. D) It was phagocytized during the countercurrent exchange. 20) What can a urinalysis test tell a health practitioner about a patient? A) whether the kidney is functioning properly B) whether the blood is too acidic C) whether the patient is having problems with their pancreas D) Any of these can be indicated by a urinalysis test.

Explanation / Answer

17)Answer-:(A) Proximal tubule,

PCT is lined by simple cuboidal brush border epithelium Which increase the surface area for reabsorption,

Nearly all of the essential nutrients and 70-80% of electrolytes and water are reabsorbed by this segment, PCT also help to maintain the PH and ionic balance of the body fluid by selective secretion of hydrogen ion,ammonia and potassium ion into the filterate and absorption of HCO3 from it,

20)Answer-:(D) Any of these can be indicated by a Urinalysis test,

•A urinalysis is commonly a part of routine health screening,

Urinalysis is commonly used to diagnosed a urinary tract (or) Kidney failure ,infection and detected and manage a wide range of disorder,

The progression of some chronic conditions such as diabetes mellitus and High blood pressure,
