Difficulty Level: Moderate
Based On: NCERT Syllabus
Introduction
Food contains different nutrients such as carbohydrates, proteins, fats, vitamins, minerals, and water. However, complex nutrients cannot always be directly used by the body. The digestive system breaks complex food substances into simpler forms that can be absorbed and utilised.
The human digestive system involves several organs that work together. Food moves through the alimentary canal, while organs such as the liver and pancreas provide important digestive secretions.
In this Practice Set 4, students will practise questions related to the alimentary canal, digestive juices, digestion, absorption, and the functions of major digestive organs.
What You Will Learn
✔ Meaning of alimentary canal
✔ Functions of digestive organs
✔ Role of the liver and pancreas
✔ Digestion of carbohydrates, proteins, and fats
✔ Importance of the small intestine
✔ Absorption of nutrients
✔ Difference between digestion and absorption
Why This Topic Is Important
The digestive system is a coordinated system in which each organ performs a specific function. Understanding these functions helps students explain how food travels through the body and how nutrients become available for use.
These concepts are also important for answering questions based on digestive-system diagrams and organ functions.
Exam Relevance
These questions are useful for:
✔ CBSE School Exams
✔ State Board Exams
✔ Unit Tests
✔ Half-Yearly Exams
✔ Annual Exams
✔ NCERT-Based Practice
✔ Science Revision
Q1. Which of the following is the correct sequence of organs through which food passes in the human alimentary canal?
A) Mouth → Stomach → Oesophagus → Small intestine → Large intestine
B) Mouth → Oesophagus → Stomach → Small intestine → Large intestine
C) Mouth → Small intestine → Oesophagus → Stomach → Large intestine
D) Mouth → Stomach → Large intestine → Oesophagus → Small intestine
Answer:
B) Mouth → Oesophagus → Stomach → Small intestine → Large intestine
Useful Detail
The alimentary canal is a continuous tube through which food passes during digestion.
The main sequence is:
Mouth → Oesophagus → Stomach → Small intestine → Large intestine → Rectum → Anus
Food is chewed in the mouth, transported through the oesophagus, processed in the stomach, and further digested and absorbed mainly in the small intestine.
The large intestine mainly absorbs water and helps form faeces.
Correct Answer: B) Mouth → Oesophagus → Stomach → Small intestine → Large intestine
Q2. Which organ produces bile?
A) Pancreas
B) Stomach
C) Liver
D) Small intestine
Answer:
C) Liver
Useful Detail
The liver is the largest gland in the human body and produces bile.
Bile is stored in the gall bladder and released into the small intestine when needed.
Bile helps in the digestion of fats by breaking large fat globules into smaller droplets.
A common mistake is to say that the gall bladder produces bile. It does not produce bile; it stores bile.
Correct Answer: C) Liver
Q3. Which of the following is NOT a function of the small intestine?
A) Completing digestion
B) Absorbing digested nutrients
C) Receiving bile and pancreatic juice
D) Storing food for a long period
Answer:
D) Storing food for a long period
Useful Detail
The small intestine performs several important functions.
It receives bile from the liver and pancreatic juice from the pancreas. These digestive juices help complete the digestion of food.
The inner wall of the small intestine contains villi that help absorb digested nutrients.
The small intestine is not primarily a storage organ. Temporary storage and mixing of food mainly occur in the stomach.
Correct Answer: D) Storing food for a long period
Q4. Which nutrient group requires digestion before it can be absorbed and used by the body?
A) Proteins
B) Vitamins
C) Minerals
D) Water
Answer:
A) Proteins
Useful Detail
Proteins are complex food substances that need to be broken down into simpler substances called amino acids during digestion.
Carbohydrates are also digested into simpler sugars, while fats are broken down into simpler components.
Vitamins, minerals, and water are generally not digested. They can be absorbed in their existing forms.
Therefore, among the given options, proteins require digestion before absorption.
Correct Answer: A) Proteins
Q5. What is the main function of the large intestine in the digestive system?
A) Producing saliva
B) Absorbing water and forming faeces
C) Producing bile
D) Digesting proteins in the stomach
Answer:
B) Absorbing water and forming faeces
Useful Detail
The large intestine receives the remaining material after food passes through the small intestine.
One of its important functions is the absorption of water and some salts from the undigested material.
As water is absorbed, the remaining waste becomes more solid and forms faeces. The faeces are then stored in the rectum before being removed from the body.
Correct Answer: B) Absorbing water and forming faeces
Important Formulas & Concepts
Science Chapter 2 does not require mathematical formulas. Important scientific concepts are given below.
1. Alimentary Canal
The alimentary canal is a continuous muscular tube through which food passes during digestion.
2. Main Path of Food
Mouth → Oesophagus → Stomach → Small Intestine → Large Intestine → Rectum → Anus
3. Liver
The liver produces bile, which helps in the digestion of fats.
4. Gall Bladder
The gall bladder stores bile produced by the liver.
5. Pancreas
The pancreas produces pancreatic juice containing digestive enzymes.
6. Small Intestine
The small intestine is the major site of digestion and absorption of nutrients.
7. Large Intestine
The large intestine absorbs water and helps in the formation of faeces.
8. Digestion of Proteins
Proteins are broken down into simpler substances called amino acids.
