Match the following (a) Small Intestine (i) Bile Juice (b) Large Intestine (ii) Acidic Medium (c) Stomach (iii) Absorption of main food nutrients (d) Liver (iv) Egestion Correct Answer (a) - (iii), (b) - (iv), (c) - (ii), (d) - (i)
Concept:
Digestion:
- it is the complex process of turning the food we eat into nutrients, which the body uses for energy, growth and cell repair needed to survive.
- It also involves creating water to be excreted.
- Human Digestive system:
- Human Digestive system consists of the alimentary canal which can be further divided into various components. a) The buccal cavity b) food pipe or oesophagus c) stomach d) small intestine e) large intestine ending in the rectum f) the anus

The stomach:
- The stomach is a thick-walled bag. Its shape is like a flattened U and it is the widest part of the alimentary canal.
- The inner lining of the stomach secretes mucous, hydrochloric acid, and digestive juices.
- The mucous protects the lining of the stomach.
- The acid kills many bacteria that enter along with the food and makes the medium in the stomach acidic, which helps digestive juices to break down the proteins into simpler substances.
The Small Intestine:
- It is highly coiled and is about 6-8 meters long. It receives secretions from the liver and the pancreas.
- The digested food can now pass into the blood vessels in the wall of the intestine. This process is called absorption.
- The inner walls of the small intestine have thousands of finger-like outgrowths.
- These are called villi. (It increases the surface area of absorption of the digested food).
Large intestine:
- It is wider and shorter than the small intestine.
- It is about 1.5 meters in length.
- Its function is to absorb water and some salts from the undigested food material.
- The waste product goes out of body through the anus.
Liver-
- The liver is the largest gland in the body.
- The liver mainly secretes 'Bile Juice' which is stored in a Gall bladder.
- Bile Juice and Pancreatic juice are released into the small intestine by a common duct.
- Unused glucose is stored in the liver in the form of glycogen.
- Heparin, Urea, and Bile Juice are produced in the liver.
Explanation:
So,
The small intestine does absrobtion.
The large intestine does egestion.
Stomach provide acidic medium.
Liver secretes bile Juice.
The correct sequences is (a) - (iii), (b) - (iv), (c) - (ii), (d) - (i)
