Question

21.- The following factors facilitate glomerular filtration except one(inward force) A.- It is a passively process in which hydrostatic pressure force fluid and solutes through a membrane. B.- The fenestration(capillary pores) allow all blood components except blood cells to pass through C.- The basement membrane electrically repels many negatively charged macromolecular anion such as plasma proteins. D.- The glomerular capillaries are drained by a high resistance efferent arteriole whose diameter is smaller than the afferent arteriole that feed them. E.-The Colloid Osmotic Pressure in Glomerular Capillaries. 22.- Glomerular Filtration Rate: A. - It is the pressure exerted by the proteins in the blood. B. - It is the volume of filtrate formed each minute by the combined activity of all 2 million glomeruli of the kidneys C.-This pressure can be controlled by changing the diameter of the afferent arterioles D. It ils mainly determined by the hydrostatic pressure in the glomerulus E. - The ability of a filtration membrane to allow another substance to pass through it membrane. 23. Find what is the correct approach to the action of ADH ( Antidiuretic Hormone ) A.-Its role is to increase blood volume, and therefore blood pressure B.-It reduces blood Na+, there by decreasing blood volume and blood pressure. , by enhancing Na+ reabsorption urine output. It makes the principal cells of the collecting duct more permeable to water by causing aquaporin to be inserted into their apical membranes.. D.- Powerful vasodilator action nsin I E.- It facilitates the conversion of angiotensinogen to angiote

Explanation / Answer

Answers

21. The factor that does not facilitate glomerular filteration rate is the inward force called the colloid osmotic pressure in glomerular cappilaries.
- This colloid osmotic pressure tends to pull the water back in capillaries decreasing the filterate rate.
Hence, Option E

22. Glomerula filteration rate is : The volume of filtrate formed per minute by the combined activity of all 2 million glomeruli of the kidneys.
Option B

23. The correct approach to the action of ADH is : It inhibits diuresis or urine output. It makes the principal cells of the collecting duct more permeable to water causing aquaporin to be inserted into apical membranes.
- ADH is released when body has low fluid volume prom posterior pituitary to prevent diuresis.
Hence, Option C
