In this process, colloidal solutions are purified by carrying out filtration throuh special types of graded filters called ultra-filters. Filter paper allows the passage of electrolyte but does not allow the passage of colloidal particles.
The given figure represents a single nephron from a mammalian kidney. Identify the labelled parts, match them with the functions (i-iv) and select the correct option. (i). The site of ultrafiltration. (ii). Particularly sensitive to ADH. (iii). The main site for the reabsorption of glucose and amino acids. (iv). Largely responsible for the maintenance of blood pH.
Describe the mechanism of ultrafiltration in Bowman's capsule.
Refer to the given figure showing structure of Malpighian corpuscle. To facilitate ultrafiltration through glomerular capillaries "______"
Read the 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
Where do ultrafiltration, reabsorption and secretion occur in a nephrom ?
The ultrafiltration process of purification of colloidal solutions is based on:
Mention the factors that favour ultrafiltration in Bowman's capsule.
