Sample questions
-
1.Match the items in Column I with those in Column II and write down the matching pairs.
Column I Column II (a) Bowman's capsule (i) Renal artery (b) Contains more CO₂ and less urea (ii) Regulates amount of water excreted (c) Antidiuretic hormone (iii) Renal vein (d) Contains more urea (iv) Glomerulus -
2.Study the diagram of the L.S. of the kidney and match the structure Renal Vein with its function.
- a.Has Malpighian capsules
- b.Carries oxygenated blood
- c.Transports urine to urinary bladder
- d.Has Henle's loops
- e.Carries deoxygenated blood
- f.Receives urine which flows into ureter
-
3.Maximum amount of water from the glomerular filtrate is reabsorbed in
- A.proximal convoluted tubule
- B.descending limbs of loop of Henle.
- C.ascending limb of loop of Henle.
- D.distal convoluted tubule.
-
4.Which of the following correctly explains the terms ultrafiltration and selective absorption in the context of the human excretory system?
- A.Ultrafiltration is the filtering of blood under high pressure in the glomerulus, allowing small molecules to pass into Bowman's capsule, while selective absorption is the reabsorption of useful substances like glucose and water back into the blood from the filtrate.
- B.Ultrafiltration is the absorption of waste products like urea into the nephron, while selective absorption is the filtering of blood to retain only large molecules like proteins in the glomerulus.
- C.Ultrafiltration occurs in the proximal convoluted tubule, where blood is filtered under low pressure, and selective absorption happens in the glomerulus to retain all nutrients.
- D.Ultrafiltration is the process of excreting urine from the bladder, while selective absorption is the reabsorption of all molecules, including waste, back into the bloodstream.
-
5.Match the following:
Excretion Egestion (a) It is the removal of metabolic wastes from the body. (a) It is the removal of undigested food material from the body. (b) It is related with kidney. (b) It is related with alimentary canal.
