Q.2. 1 mark questions. (Short answer questions)
(a) Why should we chew our food properly?

Chewing is an essential part of digestion. The more you chew, the better your food will be broken down prior to entering your stomach.

(b) Why should we eat proper food?

Good nutrition is an important part of leading a healthy lifestyle.

(c) How does a piece of bread taste after we chew it for some time?

When a piece of bread is chewed slowly, it tastes sweeter after sometime.

(d) Why do we feel weak when we have an upset stomach and vomitings?

Due to loss of water, our bodies have dehydration and this leads to electrolyte imbalance. So muscles don't work properly. That's why we feel weakness.

(e) How is digestion affected when we are sad?

Digestion slows down when we are sad. There is no effective digestion when we are sad or gloomy.

Q.3. 2 mark questions.  (Long answer questions)
(a) What is the main function of the tongue? What are the four types of tastes?

The tongue is vital for chewing and swallowing food, as well as for speech. The four common tastes are sweet, sour, bitter, and salty. A fifth taste, called umami, results from tasting glutamate.

(b) When and why is glucose drip given?

A patient needs to be on drip of glucose when the patient has loss of water and electrolytes and he is dehydrated and also when the patient can't take food orally .

(c) Who was Dr Beaumont? What did he find out about digestion?

William Beaumont, the first person to observe and study human digestion as it occurs in the stomach. He found that our stomach digests food faster than outside.

(d) Why can we not taste food properly when you have a cold?

When you have a cold, your sinuses are likely to be filled and the air with the aroma can't get past the sinus. This deprives you the sense of smell. So most of your sense of taste is gone along with your sense of smell.

(e) How does your stomach help in the digestion of food?

The stomach is like a mixer, churning and mashing together all the small balls of food that came down the oesophagus into smaller and smaller pieces. It does this with the help from the strong muscles in the walls of the stomach and gastric juices that also come from the stomach's walls.

(f) Write the symptoms a child will show if he/she does not get rice or roti to eat daily.

The visible symptoms are - Low energy, Lack of Concentration, and Giddiness. If a child does not get roti or rice during the day, he would have less energy to do any activity and feel sleepy. Without proper nutrition, the child cannot concentrate on any kind of studies or mental work. Skipping meals leads to low blood pressure which can force the child to faint down.

(g) What symptoms will a child show who eats junk food?

Anyone who eats junk food frequently will develop a pukish feeling (sometimes even puke)- develop fever, Stomach pain, Diarrhea, Dizziness, Throat infection/cold.

(h) What is the function of saliva in the mouth?


Digestion begins in the mouth. How can you say?

The digestive functions of saliva include moistening food, and helping to create a food bolus, so it can be swallowed easily. Saliva contains the enzyme amylase that breaks some starches down into maltose and dextrin. Thus, digestion of food occurs within the mouth, even before food reaches the stomach.

(i) Look at the picture of the tongue given below and mark the parts of the tongue where you can taste sweet, bitter, salty, and sour.
