Mark the correct pair of food components in human
which reach to stomach in undigested form
(1) Starch and fat
(2) Starch and Protein
(3) Starch and Cellulose
(4) Cellulose and fat
Mark the incorrect statement
(1) Fructose, mannose and some amino acids are
absorbed by facilitated diffusion
(2) Various nutrients like amino acids, fatty acid,
monosaccharides like glucose, electrolytes like
are absorbed by active transport only
(3) Fatty acid and glycerol are first incorporated
into small droplets called micelles which move
into intestinal cell of mucosa
(4) Transport of water depends upon osmotic
gradient
Principal organ for the absorption of nutrients is
1. Buccal cavity
2. Stomach
3. Small intestine
4. Large intestine
Process of conversion of complex food substances to simple absorbable form is called :-
1. Assimilation
2. Deamination
3. Digestion
4. Absorption
Alimentary canal begins with :-
1. An vertical slit, the mouth
2. An anterior opening, buccal cavity
3. An ventral slit, the mouth
4. An opening, the mouth
Match the following columns and choose the correct answer from the options given below
a. Indigestion (i) Ejection of stomach contents through the mouth
b. Constipation (ii) It reduces the absorption of food
c. Diarrhoea (iii) The faeces are retained in the rectum as the bowel movements becomes irregular
d. Vomiting (iv) Food is not properly digested
1. a-iv, b-i, c-ii, d-iii
2. a-iv, b-iii, c-i, d-ii
3. a-i, b-ii, c-iii, d-iv
4. a-iv, b-iii, c-ii, d-i
Bile duct and pancreatic duct open together
into the duodenum as the common hepato-
pancreatic duct which is guarded by a sphincter
called
(1) Sphincter of Boyden
(2) Pyrolic sphincter
(3) Sphincter of Oddi
(4) Gastro-oesophageal sphincter
Mark the condition where food is not properly
digested leading to feeling of fullness. This can be
caused due to inadequate secretion, food
poisoning, over eating etc.
(1) Vomiting
(2) Constipation
(3) Indigestion
(4) Diarrhoea
Match the following
Column I Column II
a. Sphincter of boyden (i) Regulates openings of
oesophagus into
stomach
b. Sphincter of Oddi (ii) Surrounds the
opening of bile duct
into pancreatic duct
c. Cardiac sphincter (iii) Regulates the
opening of stomach
into small intestine
d. Pyloric sphincter (iv) Surrounds ampulla of
vater
(1) a(ii), b(iv), c(iii), d(i)
(2) a(iv), b(ii), c(i), d(iii)
(3) a(iv), b(i), c(iii), d(ii)
(4) a(ii), b(iv), c(i), d(iii)
