  • Question 1
    1 / -0
    Ultrafiltrate generated by the glomerulus has all the constituents of the blood plasma except
    Solution
    Ultrafiltrate generated by the glomerulus has all the constituents of the blood plasma except Proteins because proteins are relatively larger in physical size and cannot pass through the minute pores called filtration slits or slit pores present in the epithelial layer of Bowman's capsule.
    So, the correct answer is 'Protein'.
  • Question 2
    1 / -0
    Collecting duct of nephron extends kidney from cortex to 
    Solution
    A. Capsule region or renal capsule is a fibrous layer that surrounds the kidney.
    B. Medulla is the innermost part of the kidney.
    C. Hilus or hilum is a deep notch or a cavity present in the medial portion of kidney.
    D. Ureters are the ducts through which urine passes from kidneys to the bladder.
    Collecting ducts are the last parts of nephrons and extends from cortex to the medulla in the kidneys.
    So, the correct answer is 'Medulla'.
  • Question 3
    1 / -0
    If the GFR is 140 ml/min and the filtration fraction is 20%, then the renal plasma flow (RPF) is _______ ml/min.
    Solution
    GFR or Glomerular filtration rate is the amount of filtrate formed by kidneys per minute.
    RPF or Renal plasma flow is the amount of blood plasma that is delivered to kidneys.
    Filtration fraction or FF is the ratio of GFR to RPF.
    Therefore, FF = GFR/RPF
    In the given question, GFR = 140 ml/min and FF= 20 % or 0.20
    Putting the values in the formula,
    0.20 = 140/RPF
    RPF = 140/0.20 = 700
    So, the correct answer is '700'.
  • Question 4
    1 / -0
    Frog is 
    Solution
    A) Ammonotelic is an animal which excretes ammonia.
    B) Ureotelic is an animal which excretes urea.
    C) Uricotelic is an animal which excretes uric acid.
    Since, frogs excrete ammonia, they are known as ammonotelic.
  • Question 5
    1 / -0
    Removal of proximal convoluted tubule from the nephron will result in
    Solution
    Correct Answer :C
    Explanation :
    • The kidney has proximal convulated tubule which is responsible for the absorption of the material such as glucose, salts, proteins and ions such as potassium and sodium.
    • If the proximal convulated tubule will be removed, it will result in malfunctioning of the kidney.
    • In absence of absorption, the urine will be more diluted .
    • Hence, the correct answer is C. More diluted urine
  • Question 6
    1 / -0
    The bunch of blood capillaries of nephron is called ..............
    Solution
    Each nephron consists of a Malphigian body, proximal and distal convoluted tubule and a collecting duct. The Malphigian body contains a cup like structure, the Bowman's capsule and a tuft or bunch of capillaries called the glomerulus
    So, correct answer is 'None of the above'
  • Question 7
    1 / -0
    The net pressure gradient that causes the fluid to filter out of the glomeruli into the capsule is
    Solution
    Correct Answer : C
    Explanation :
    • In the kidney, the fluid to be filtered out of the glomeruli into the capsule, a pressure gradient is required.
    • The net pressure gradient is 20mm Hg.
    • One-fifth of the plasma fluid is filtered out of the Bowman's capsule. The filtration rate is 10-15mm Hg.
    • Hence, the correct option is C. 20mm Hg.
  • Question 8
    1 / -0
    The two main parts of nephron are
    Solution
    A) Bowman's capsule is a cup-like structure at the beginning of the tubular component of a nephron. Renal tubules are long, fine, convoluted tubules which deliver urine from the glomeruli to the renal pelvis.
    B) The glomerulus is a tuft of capillaries located inside the Bowman's capsule. 
    C) Bowman's capsule and glomerulus are a part of the nephron.
    D) The glomerulus along with the Bowman's capsule is called as the malpighian body.
    So the correct answer is 'Glomerulus and renal tubule'.
  • Question 9
    1 / -0
    What is the excretory unit in human being?
  • Question 10
    1 / -0
    Find out the incorrect statement :

    Solution
    A) Ammonia is the most toxic form and requires a large amount of water for its elimination this is the reason it is necessary to eliminate it from the body. B)Kidneys do not play an important role in ammonia removal as it is converted into urea in the liver and then removed by the kidneys. C) Human kidneys can only produce hypertonic urine nearly five times concentrated than the initial to maintain the water level inside the body. D)Urea may be retained in the kidney matrix of some animals to maintain the desired osmolarity as chemical changes occur which leads to an adverse effect on the body. So the correct option is 'Urea may be retained in the kidney matrix of some animals to maintain the desired acidity'.
