  2. 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 .

  3. 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.

  4. 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.

  5. The stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus 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.

  6. 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.

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

  8. 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.
