  • Question 1
    1 / -0
    Choose the odd one out and give scientific reasons.
    Solution
    The odd one among the organs is the heart. the reason the heart is the odd one in the list because all the other organs are involved in some excretory function except for the heart. The function of the heart is to pump oxygenated blood throughout our body; it has nothing to do with any kind of excretion in the human body.
    So, the correct answer is C.
  • Question 2
    1 / -0
    Kidneys are made up of number of filters called _______.
    Solution
    Each of kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.
    Hence, the correct answer is (A)
  • Question 3
    1 / -0
    ________ produces bile pigments from the haemoglobin of broken red blood cells.
  • Question 4
    1 / -0
    The network of blood capillaries present in the Bowman's capsule is called?
  • Question 5
    1 / -0
    Filtration of blood occur in ________.
    Solution
    • Blood is filtered at the glomerulus that is a network of fine capillaries present in the Bowman's capsule of a nephron.
    • The process is known as glomerulus filtration in which fluid, ions, glucose, and nitrogen waste products are removed from the blood.
    • The Bowman's capsule collects the filtrate and passes it to the next parts of the nephron, namely the proximal tubule, the loop of Henley and the distal tubule. The filtrate is processed in the tubules finally to form urine.

    So, the correct answer is option B.

  • Question 6
    1 / -0
    The knot of blood vessel inside the Bowman's capsule is the?
    Solution
    The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. The Bowman's capsule surrounds a ball of capillaries called the capillary knot. high pressure is created in the capillary knot by the diameter of the capillary leaving the knot being narrower than the capillary entering.
    Hence, the correct answer is (B)
  • Question 7
    1 / -0
    Which of the following is not a part of the structure of uriniferous tubule?
  • Question 8
    1 / -0
    Which of the following are absent in both serum and glomerular filtrate?
    I. Ions
    II. RBC
    III. Fibrinogen
    IV. Albumin.
    Solution

    Serum does not include formed elements or blood cells and also the clotting factors or proteins as serum is the after clot component of the blood, however, it does contain other albumin and ions. Similarly, glomerular filtate contains ions and  a negligent amount of albumin
    So, the correct answer is (B)

  • Question 9
    1 / -0
    Choose the correct answer from the our options given.
    The smallest functional unit of kidney is?
    Solution
    The smallest functional unit of kidney is Nephron.
    So, the correct answer is (D)
  • Question 10
    1 / -0
    Ultrafiltration occurs in a glomerulus when?
    Solution
    Glomerulus is responsible for filtration. GFR depends on :-
    (i) glomerular hydrostatic pressure - it supports filtration
    (ii) colloid osmotic pressure - it opposes filtration
    (iii) capsular hydrostatic pressure - it opposes filtration
    So the net filtration rate is equal to colloidal osmotic pressure plus capsular pressure remains less than hydrostatic pressure.
    Hence, the correct answer is (D)
