The organs A of a person have been damaged completely due to which too much of a poisonous waste material B has started accumulating in his blood, making it dirty . In order to save this person's life, the blood from an artery in the person's arm is made to flow into long tubes made of substance E which are kept in coiled form in a tank containing solution F. This solution contains three materials G, H and I in similar proportions to those in normal blood. As the person's blood passes through long tubes of substance E, most of the wastes present in it go into solution. The clean blood is then put back into a vein in the arm of the person for circulation.(a) What are organs A?(b) Name the waste substance B.(c) What are (i) E, (ii) F?(d) Name G, H and I.(e) What is the process described above known as ?
(a) Organs A is Kidneys.
Explanation: Complete damage to the kidney (A) can lead to the accumulation of wastes in the blood.
(b) The waste substance B is Urea.
Explanation: Complete damage to the kidney can lead to the accumulation of waste materials like urea (B) in the blood.
(c) (i) E is Cellulose.
Explanation: During dialysis, the blood from an artery in the person's arm is made to flow into long tubes made of cellulose (E).
(ii) F is a Dialysing solution.
Explanation: During dialysis, the blood from an artery in the person's arm is made to flow into long tubes made of cellulose (E) which are kept in a coiled form in a tank containing Dialysing solution (F).
(d) G, H, and I are Water, Glucose, and Salts, respectively.
Explanation: Dialysing solution contains three materials Water (G), Glucose (H), and Salts (I) in similar proportions to those in normal blood.
(e) The process of removing wastes from the blood, externally using a machine is known as Dialysis.

- There is a pair of bean-shaped organs P in the human body towards the back, just above the waist. A waste product Q formed by the decomposition of unused proteins in the liver is brought into organ P through blood by an artery R. The numerous tiny filters S present in organs P clean the dirty blood by removing the waste product Q. The clean blood goes into circulation through a vein T. The waste substance Q, other waste salts, and excess water form a yellowish liquid U which goes from organ P into a bag-like structure V through two tubes W. This liquid is then thrown out the body through a tube X.(a) What is (i) organ P, and (ii) waste substance Q?(b) Name (i) artery R, and (ii) vein T.(c) What are tiny filters S known as ?(d) Name (i) liquid U (ii) structure V (iii) tubes W, and (iv) tube X.
- The human body has an organ A which acts as a double pump. The oxygenated blood coming from the lungs through a blood vessel B enters the upper left chamber C of the double pump. When chamber C contracts, then blood goes into lower left chamber D. The contraction of chamber D forces the blood to go into a blood vessel E which supplies oxygenated blood to all the organs of the body (except the lungs). The deoxygenated blood coming out of the body organs is taken by a blood vessel F to the right upper chamber G of pumping organ. Contraction of chamber G forces the deoxygenated blood into right lower chamber H. And finally the contraction of chamber H sends the deoxygenated blood into lungs through a blood vessel I.
- An organism A which cannot move from one place to another, makes a simple food B from the substances C and D available in the environment. This food is made in the presence of a green coloured substance E present in organs F in the presence of light energy in a process called G. Some of the simple food B also gets converted into a complex food H for storage purposes. The food H gives a blue-black colour with dilute iodine solution.

- When a person eats sugary food, then organisms A present in his mouth act on sugar to produce a substance B. The substance B first dissolves the calcium salts from the top part C of the tooth and then from its middle part D forming holes E. These holes ultimately reach the part F in the lower part of tooth which contains nerves and blood vessels. The substance B irritates the nerve endings inside the tooth causing toothache.(a) What are (i) organisms A, and (ii) substance B?(b) What are (i) part C, and (ii) part D, of tooth known as?(c) By what name are the holes E in the tooth known?(d) Name the part F of the tooth.(e) What will happen if organisms A reach part F of the tooth?
- When a person breathes in air, the air enters into his body through an organ A having two holes B in it. The air then passes through pharynx and larynx and enters into a tube C. The tube C divides into two smaller tubes D at its lower end. The two smaller tubes are attached to two respiratory organs E. Each smaller tube divides inside the organs E to form a large number of still smaller tubes called F. The smallest tubes F have air-sacs G at their ends in which gaseous exchange takes place in the body of the person. What are A, B, C, D, E, F and G ?
- When a person puts food in his mouth, then teeth cut it into small pieces, chew and grind it. The glands A in the mouth secrete a substance B which is mixed with the food by tongue. The substance B contains an enzyme C which starts the digestion of food in the mouth. The slightly digested food from the mouth goes down a tube D. The special type of movements E in the walls of tube D push the food into stomach for further digestion. The stomach wall secretes gastric juice containing three substance F, G and H. One of the functions of F is to kill bacteria which may enter the stomach with food. The substance G protects the inside layer of stomach from the damaging effect of substance F whereas substance H is an enzyme for digestion. The partially digested food then enters into small intestine for further digestion.(a) What is (i) gland A (ii) substance B, and (iii) enzyme C?(b) Name the tube D.(c) What is the movement E known as?(d) What are (i) F (ii) G, and (iii) H?

- The partially digested food coming from the stomach of a person enters a long and narrow organ A in his body. The organ A receives the secretions of two glands : liver and pancreas. Liver secretes a greenish yellow liquid B which is normally stored in the organ C. Pancreas secretes pancreatic juice which contains three digestive enzymes D, E and F. The intestinal juice completes the process of digestion of food. The inner wall of organ A has millions of tiny finger-like projections G which help in the rapid absorption of digested food into blood stream. The undigested part of food then passes into wider tube H which absorbs most of the water form undigested food. The last part of tube H called I stores this undigested food (or waste) foe some time. The indigested food is then passed out through opening J as faeces in the process known as K.(a) Name the organ A.(b) Name (i) liquid B, and (iii) organ C.(c) What are the digestive enzymes D, E and F?(d) Name the projections G present on the inner wall of organ A.(e) Name (i) tube H (ii) part I (iii) opening J, and (iv) process K.
