Question

5. "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 from undigested food. The last part of tube H called I stores this undigested food (or
waste) for some time. The undigested food is then passed out though opening J as faeces in the process
known as K.
(a) Name the organ A.
(b) Name (1) liquid B, and (ii) 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 (1) tube H (ii) part I (iii) opening J, and (iv) process K.
