Draw a labelled diagram of the human digestive system. With the help of this diagram, describe the process of digestion of food in man (humans).
The length of small intestine in a human adult is about:
(a) 4.5 m
(b) 1.5 m
(c) 3.5 m
(d) 6.5 m
In human digestive system, bile is secreted by:
(a) pancreas
(b) liver
(c) kidneys
(d) stomach
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 secretion 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.
