Comment upon the following: Diameter of afferent arteriole and its capillaries is more than the diameter of efferent arteriole and its capillaries.

The glomerulus is a network of capillaries within the cup of the Bowman's capsule .

Which of the following hormone acts upon the renal tubule and blood capillaries?

Trace the changes in water and carbohydrate contents of the glomerulus filtrate as it passes through the renal tubules of a person suffering from diabetes mellitus.

In a device designed by Academician Rebinder the surface tension is determnined from the pressure difference required to form a bubble of air at the end of a capillary immersed in the liquid being investigated (fig). Calculated the surface tension if the radius of the capillary is r = 1 mm and the difference in the pressures during bubble formation is DeltaP = 14 mm of water column. The end of the capillary is near the surface of the liquid.

select the correct option: a. Glomerulus is a a tuft of capillaries formed by the afferent articles which is a fine branch of renal vein b. Giomerulus along with the bowman's capsule forms renal corpuscle c. Vasa recta is a find branch of afferent arteriole which runs parallel to Henie's loop d. in human kidney, cortical nephron and juxtamedullary nephrons are in equal proportion

High blood pressure is maintained in glomeruli than in other capillaries because (a) The variability of the diameters of arterioles causes higher resistance to blood flowing out of the glomeruli than that flowing out of the capillaries (b) Glomerulus has low hydrostatic pressure than capillary (c) Capillary has lesser diameter than glomerulus (d) All the above

Read following statements regarding various steps of urine formation. A. Blood flows through glomerular capillaries under a pressure created due to difference in diameter of afferent and efferent arterioles. B. Filtrate formed after ultrafiltration is isotonic to blood plasma. C. Reabsorption of glucose occurs throughout the tubules of nephron. D. Selective tubular secretion of H^+ and K^+ ions help in maintaining ionic balance of body. Select the option having only correct statements 1) A and C 2) B , C and D 3) A , B and D 4) C and D

Passage : Post office is useful to measure the value of unknown resistance correctly upto 2nd decimal place. It is based on Wheatstone bridge. Systematic diagrams of post office box are shown in the above figures. Each of the arms AB and BC contains three resistance of 10 Omega, 100 Omega and 1000 Omega . These arms are generally known as ratio arms. With the help of these resistance, we can introduce resistance P in arm AB and Resistance Q in arm BC. The resistance arm AD is complete resistance box containing resistance from 1 Omega "to" 5000 Omega . In this arm, we can introduced resistance R by taking out plugs of suitable values. The unknown resistance X is connected in fourth arm CD. These four arms actually form Wheatstone bridge shown in figure. For balanced conditions, no deflection is formed in galvanometer. At balanced condition PX= QR , X= (QR)/( P) While measuring surface tension of water using capillary rise method the necessary precaution to be taken is/are
