Question 1
1 / -0

The teeth occur in human beings are

A
monophyodont, homodont and thecodont

B
monophyodont, heterodont and acrodont

C
diphyodont, heterodont and thecodont

D
diphyodont, homodont and acrodont

Solution

Each tooth is embedded in a socket of jaw bone called thecodont. Human being forms two sets of teeth during their life temporary milk or deciduous teeth replaced by a set of permanent or adult teeth called diphyodont. An adult human has 32 permanent teeth which are of four different types called heterodont.
Question 2
1 / -0
Complete the following reaction :
- Maltose — Maltase → Glucose + i
- Lactose — Lactase → Glucose + ii
- Sucrose — Sucrase → Glucose + iii
A

i-mannose

ii-glucose

iii-galactose
B

i - glucose

ii - galactose

iii - fructose
C

i-galactose

ii-glucose

iii-fructose
D

i-fructose

ii-galactose

iii-glucose
Solution

Maltose in presence of maltase produce two molecules of glucose. Lactose in presence of lactase produce glucose and galactose. Sucrose in presence of sucrose produce glucose and fructose.
Question 3
1 / -0

Which of the following is not a part of colon?

A
Longitudinal colon

B
Ascending colon

C
Transverse colon

D
Pelvic colon

Solution

The colon is divided into three parts – an ascending, a transverse and a descending part.
Question 4
1 / -0

Brunner’s gland is

A
Hepatic-pancreatic duct

B
Gastro-intestinal sphincter

C
Sub-mucosal gland

D
Gastric gland

Solution

Brunner’s glands are submucosal mucin secreting glands localized predominantly in the duodenal bulb and proximal duodenum, decreasing progressively in size and number in the distal portions.

Sub-mucosal glands (Brunner’s glands) provide alkaline medium.

Question 5

1 / -0

Match the cells and their secretions:

Cell Type	Secretion
a) Goblet cell	i) succusentericus
b) Oxyntic cells	ii) mucus
c) Chief cells	iii) acid
d) Intestinal gland cells	iv) pepsinogen

a) - ii

b) - iii

c) - iv

d) - i

a) - ii

b) - i

c) - iv

d) - iii

a) - iv

b) - i

c) - ii

d) - iii

a) - ii

b) - iii

c) - i

d) - iv

Solution

The intestinal mucosal epithelium has goblet cells which secrete mucus. The secretions of the brush border cells of the mucosa along with the secretions of the goblet cells constitute the intestinal juice or succusentericus. The peptic or chief cells which secrete the proenzyme pepsinogen. The parietal or oxyntic cells secrete HCl acid.

Question 6
1 / -0

All are digestive glands except :

A
Liver

B
Pancreas

C
Thyroid gland

D
Salivary gland

Solution

The thyroid is part of the endocrine system, which is made up of glands that produce, store, and release hormones into the bloodstream so the hormones can reach the body's cells.

The thyroid gland uses iodine from the foods you eat to make two main hormones:

Triiodothyronine (T3) Thyroxine (T4)
Question 7
1 / -0

_____ from pharynx is conveyed into oesophagus by _____ .

A
Chyme, regurgition

B
Bolus, deglutition

C
Bolus, regurgition

D
Chyme, degluition

Solution

The bolus is then conveyed into the pharynx and then into the oesophagus by swallowing or deglutition.
Question 8
1 / -0

The bile duct and the pancreatic duct open together into the duodenum as

A
Hepatic duct

B
Cystic duct

C
Duct of liver

D
Hepato-pancreatic duct

Solution

The bile duct and the pancreatic duct open together into the duodenum as the common hepato-pancreatic duct which is guarded by a sphincter called the sphincter of Oddi.

Question 9
1 / -0

Digestion can be defined as :

A
reduction of food molecules to produce energy.

B
breakdown of simple molecules into absorbable forms

C
intake and direct cellular ulilisation of biomacromolecules present in food.

D
breakdown of complex molecules into absorbable forms

Solution

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.

In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
