  • Question 1
    1 / -0
    Glucose is taken back from glomerular filtrate through
    Solution
    Correct Option: A
    Explanation:
    • All of the aldohexoses that were originally filtered out through capillary are reabsorbed within the blood capillary. 
    • The organic process(reabsorption )of glucose and mineral ions in the tubule takes place by active transport. 
    • The cells that form up the wall of the nephron are custom-made by having a plicate membrane (providing a large surface area) and an outsized variety of mitochondria (to supply the energy for active transport). Whereas the reabsorption of water takes place passively by diffusion(osmosis). Hence, Glucose is taken back from capillary vessel filtrate through Active transport.
  • Question 2
    1 / -0
    Glomerulus and Bowmans capsule constitute
    Solution
    Nephrons are the cells of kidney which are composed of a renal corpuscle and a renal tubule.  The renal corpuscle is also known Malpighian body. It consists of cup like double walled structure known as Bowman’s capsule and the bunch of capillaries present in the Bowman’s capsule is known as glomerulus. It helps in filtration of blood at high pressure. So, the correct answer is option 'Malpighian body'.

  • Question 3
    1 / -0
    The basic structural/functional unit of kidney is
    Solution
    Nephrons are the cells of kidney which are considered as smallest functional unit because it is microscopic structure which actively participates in functions of kidney like blood filtration and osmoregulation. A healthy adult has 0.8 to 1.5 million nephrons in each kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle filters the blood components. The filtrate is transferred to renal tubule for process of tubular secretion and tubular reabsorption which further forms the urine by maintaining its concentration. So the correct answer is 'Nephron'.
  • Question 4
    1 / -0
    Substrate which is not reabsorbed in urine is
  • Question 5
    1 / -0
    Henles loops occur in
    Solution
    In mammals the excretory organ is Kidney. The nephron is the structural and functional unit of the kidney. The body of the nephron is divided into renal corpuscle (Glomerulus and its surrounding Bowmans capsule), Proximal convoluted tubule( PCT), Henle's loop and Distal convoluted tubule( DCT). Hence, Henle loops occur in nephrons of mammals.
    So, the correct answer is 'Nephrons of mammals'.
  • Question 6
    1 / -0
    Filtration occurs in 
    Solution
    Bunch of capillaries present in the Bowman’s capsule is known as glomerulus. The process of filtration in the glomerulus is known as ultrafiltration. The blood enters the glomerulus under high pressure from the afferent arteriole and leaves through efferent arteriole. Due to the high pressure in the glomerulus, the blood gets filtered into the Bowman's capsule by the process of glomerular filtration. The glomerular filtrate contains water, glucose, salts and urea. The filtered blood has platelets, RBC, fat and WBC's.
    So the correct answer is 'Glomerulus'.
  • Question 7
    1 / -0
    Bony fishes are
    Solution
    Ammonia is excretory material in bony fishes because ammonia is a excretory product which is a very toxic substance to tissues and extremely soluble in water. It requires large amount of water to dissolve, about 0.5 L of water is needed per 1 g of nitrogen to maintain ammonia levels in the excretory fluid below the level in body fluids to prevent toxicity. So, this mode of excretion is desirable in aquatic animals. The process of excretion of ammonia is known as ammonotelic.
    So, the correct answer is 'Ammonotelic'.
  • Question 8
    1 / -0
    Bowmans capsule is constituent of
    Solution
    The nephron is the structural and functional unit of the kidney. The body of the nephron is divided into renal corpuscle (Glomerulus and its surrounding Bowmans capsule), Proximal convoluted tubule( PCT), Henle's loop and Distal convoluted tubule( DCT). The nephrons along with collecting ducts are called as uriniferous tubules. Hence Bowman's capsule is a constituent of 'Uriniferous tubule'.
    So, the correct answer is 'Uriniferous tubule'.
  • Question 9
    1 / -0
    Function of loop of Henle is 
    Solution
    The nephron is the structural and functional unit of the kidney. The body of the nephron is divided into renal corpuscle, proximal convoluted tubule ( PCT), Henle's loop and distal convoluted tubule( DCT). The primary function of the Loop of Henle is the recovery of water and sodium chloride from the filtrate. Hence function of Loop of Henle is conservation of water.
    So, the correct answer is 'Conservation of water'.
  • Question 10
    1 / -0
    Duct of Bellini is connected with
    Solution
    The most distal portion of collecting duct is called as Ducts of Bellini. They receive renal filtrate from several collecting ducts and open into the minor calyx. Hence Ducts of Bellini is connected with collecting duct.
    So, the correct answer is 'Collecting duct'.
