Question 1
1 / -0

In the given figure of human tooth, some parts are labelled as A, B, C and D. Identify these parts and match them with their description given below.
(i) Contains dentine producing cells
(ii) 70% mineral matter, mainly calcium
(iii) Hardest material in the body
(iv) Connects root to the jawbone

A
A-(i), B-(ii), C-(iii), D-(iv)

B
A-(ii), B-(iii), C-(iv), D- (i)

C
A-(iii), B-(ii), C-(iv), D-(i)

D
A-(ii), B-(iii), C-(i), D- (iv)
Question 2
1 / -0

Which of the following part/s of the human digestive system involves both chemical and mechanical ways of digestion?

A
Oesophagus

B
Stomach

C
Mouth

D
Both B and C

Solution

A) Oesophagus:-It is a long tube-like structure that leads food from mouth to stomach by peristalsis movement of muscles.
B) Stomach:- It is the digestive part which is J shaped and store food for around 4-5 hours and churns the food with churning movement along with it gastric acid and pepsin are mixed with the food which helps in the digestion of protein.
C) Mouth:-It is the first part of the digestive tract where food is broken down into a paste by teeth and digestion of starch starts here with the help of the enzyme salivary amylase.
So the correct option is 'Both B and C'.
Question 3
1 / -0

The given figure shows the arrangement of different types of teeth in the jaw on one side. Identify A, B, C, and D.
A B C D

A
Incisors, Canine, Premolars, Molars

B
Molars, Premolar, Canines, incisors

C
Premolars, Molar, Incisors, Canines

D
Incisors, Canine, Molars, Premolars

Solution

A. Incisors, Canine, Premolars, Molars.
Solution: The Incisors are present in the front of the mouth that are involved with the biting of food. The canines are after the incisors that are involved with the tearing of the food. The premolars and molars are at the end that is involved with grinding.
So the correct answer is " Incisors Canine Premolars Molars.".
Question 4
1 / -0

The food we take in our body travels through a long and complex path starting from mouth to anus. Which is the correct sequence of processes on food in the digestive system?

A
Digestion $$\rightarrow$$ Absorption $$\rightarrow$$ Egestion $$\rightarrow$$ Ingestion

B
Ingestion $$\rightarrow$$ Egestion $$\rightarrow$$ Digestion $$\rightarrow$$ Absorption

C
Digestion $$\rightarrow$$ Ingestion $$\rightarrow$$ Absorption $$\rightarrow$$ Egestion

D
Ingestion $$\rightarrow$$ Digestion $$\rightarrow$$ Absorption $$\rightarrow$$ Egestion
Solution
Ingestion- Ingestion means intake of food into the mouth and chewing of food.
Digestion- Ingested food enters into the stomach where digestion of food takes place. Many digestive juices get mixed with food and digestion gets completed.
Absorption- Digested food enters the intestine. The absorption of food takes place in the intestine. The intestine has many finger-like projections which are known as villi. Villi help in the absorption of food.
Egestion- It is simply the removal of undigested food from the anus.
Therefore, the correct sequence of processes on food in the digestive system is Ingestion $$\rightarrow$$ Digestion $$\rightarrow$$ Absorption $$\rightarrow$$ Egestion
Thus, the correct answer is option D.
Question 5
1 / -0

Which of the following part is excluded from the study of T.S. of gut.

A
Pharynx

B
Esophagus

C
Colon

D
Rectum

Solution

Esophagus, colon and rectum are studied with the T.S. of the gut. They are all a part of the digestive system where is wearing is a part of the digestive as well as the respiratory system and it is not studied along with them.
So the correct option is 'Pharynx'.
Question 6
1 / -0

In which organ the digestion of protein starts in the human digestive tract?

A
Mouth

B
Oesophagus

C
Stomach

D
Small intestine

Solution

It begins in the stomach by pepsin which breaks down the peptide bind and makes protein smaller for easier digestion. Trypsin and chymotrypsin are also enzymes that are created by the pancreas and will cut down proteins into small peptides.

So the correct option is "stomach".
Question 7
1 / -0

The following are the functions of organs or regions of the digestive system. Choose option with the incorrect description.

A
Liver- Absorption

B
Mouth - Chewing and grinding

C
Large intestine - Absorption of water and salts

D
Stomach- Digestion
Question 8
1 / -0

The amino acid _____ is obtained by microbial process by lactobacillus delbrueckii.

A
itaconic acid

B
lactic acid

C
gluconic acid

D
citric acid

Solution

Lactobacillus delbrueckii is a beneficial bacteria found in the digestive tract. The proper balance of gut flora helps to keep your intestinal walls strong and bad bacteria at bay and can reduce the risk of chronic disease. which are highly adapted to growing on lactose and converting it into lactic acid.
So the correct answer is "Lactic acid".
Question 9
1 / -0

Consider the following statement regarding human.
a. Duodenum is the longest part of small intestine
b. Hepatic and cystic ducts release their secretions into common bile duct whose opening is controlled by sphincter of Oddi
c. Ileocaecal valve is present at the junction of small intestine and large intestine
d. Mechanical digestion and chemical digestion of food occurs in buccal cavity, stomach and small intestine
Which of the following choices is correct?

A
A and B only

B
B and C only

C
C and D only

D
A, B, C and D

Solution

a. Ileum is the longest part of small intestine.
b. Bile duct and pancreatic duct open together into the duodenum as the common hepato-pancreatic duct which is guarded by a sphincter called the sphincter of oddi.
c. Ileocaecal valve is present at the junction of small intestine and large intestine.
d. Mechanical digestion and chemical digestion of food occurs in buccal cavity, stomach and small intestine.
a and b are wrong. c and d are correct.
So, the correct answer is 'C and D only'
Question 10
1 / -0

The given schematic diagram depicts heterodont teeth and its thecodont arrangement . Find the correct labelling for A - D fom the options given below.

A
A - Incisor, B- Canine, C - Premolar , D- Molar

B
A - Molar , B - Premolar, C -Canine , D-Incisor

C
A - Incisors, B-Premolar, C-Canine , D- Molar

D
A - Molar, B- Premolar, C-Incisor, D- Canine
Solution
- Humans have heterodont teeth as we have four different types of teeth namely- incisors, canines, molars, and premolars.
- The teeth in humans are embedded deep in the sockets of the jaw bone hence, called the thecodont.
1) Incisors- we have 4 incisors each on the upper and lower.
Function- Its main function is to bite the food.
2) Canines- we have two canines on the upper and lower jaw.
These are the sharpest teeth.
Function- It helps to tear the food.
3) Premolars- are also known as bicuspids.
We have two premolars each on the upper and the lower jaw.
Function- they help in chewing and grinding food.
4) Molars- we have 3 molars each on the upper and lower jaw.
Function- they also help in chewing and grinding food.
The dentition in humans is 2123- incisors-2, canines-1, premolars- 2, molars- 3.
So, the correct answer is 'A - molar, B - premolar, C - canine, D-incisor'.
