PREVIOUSThe 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.(a) What is organ A ?(b) Name the blood vessel (i) B (ii) E (iii) F, and (iv) I.(c) What are chambers (i) C, and (i) D?(d) What are chambers (i) G and (ii) H ?NEXTThere 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 organ 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 Vthrough two tubes W. This liquid is then thrown out of 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.
