Here's Hands out /some questions-Answers on the human digestive system
Q # 01: What is the function of the digestive system in the human body?
1. The function of the digestive system is to break down
food into nutrients that can be absorbed and used by the body, and to eliminate
waste materials.
Name the organs of the digestive system in the order in which
food passes through them.
Q # 02: Name the
organs of the digestive system in the order in which food passes through them ?
2. The organs of the digestive system in the order of food
passage are the mouth, esophagus, stomach, small intestine, large intestine
(colon), rectum, and anus.
Q # 3. What is the
role of the mouth in the digestive system?
3. The mouth plays a vital role in the digestive system. It
helps in the mechanical digestion of food through chewing and mixes food with
saliva, which contains enzymes that start the chemical digestion of
carbohydrates.
Q # 4. What is the
function of the esophagus?
4. The esophagus is a muscular tube that connects the mouth
to the stomach. Its function is to transport chewed food from the mouth to the
stomach using muscular contractions called peristalsis.
Q # 5. What is the
main function of the stomach?
5. The main function of the stomach is to break down food
mechanically and chemically. It mixes food with gastric juices, including
hydrochloric acid and enzymes, to further break down proteins and kill
bacteria.
Q # 6. How does the
small intestine contribute to digestion and absorption?
6. The small intestine contributes to digestion and
absorption. It receives partially digested food from the stomach and completes
the digestion process using enzymes produced by the pancreas and its own cells.
It also absorbs nutrients into the bloodstream.
Q # 7. Name two
accessory organs of the digestive system and describe their functions.
7. Two accessory organs of the digestive system are the
liver and pancreas. The liver produces bile, which helps in the digestion and
absorption of fats. The pancreas produces enzymes that aid in the digestion of
carbohydrates, proteins, and fats.
Q # 8. What is the
function of the large intestine?
8. The large intestine absorbs water, electrolytes, and some
vitamins from the remaining undigested food. It also helps in the formation and
elimination of feces.
Q # 9. Explain the
process of digestion in the small intestine.
9. In the small intestine, food mixes with enzymes from the
pancreas and intestinal cells. These enzymes break down carbohydrates,
proteins, and fats into smaller molecules that can be absorbed through the
intestinal lining into the bloodstream.
Q # 10. How does the
digestive system help in the absorption of nutrients?
10. The digestive system helps in the absorption of
nutrients by breaking down food into smaller molecules that can be easily
absorbed through the lining of the small intestine into the bloodstream.
Nutrients are then transported to various parts of the body to be used for
energy and growth.
Q # 11. Briefly
explain the role of enzymes in the digestive process.
11. Enzymes are biological catalysts that speed up chemical
reactions in the body. In the digestive system, enzymes break down complex food
molecules into simpler substances. For example, amylase breaks down starch into
simple sugars, and proteases break down proteins into amino acids.
Q # 12. What happens
to undigested food in the digestive system?
12. Undigested food, along with waste materials and water,
passes from the small intestine to the large intestine (colon). The colon
absorbs water and electrolytes from the waste, forming feces. The feces are
then eliminated from the body through the rectum and anus.
Q # 13. Name three common digestive disorders and briefly explain each
one.
13. Three common digestive disorders are:
a) Acid reflux or gastro
esophageal reflux disease (GERD) - stomach acid flows back into the esophagus,
causing heartburn and irritation.
b) Irritable bowel
syndrome (IBS) - a functional disorder characterized by abdominal pain,
bloating, and changes in bowel habits.
c) Constipation -
difficulty in passing stools due to slow movement of waste through the colon.
Q # 14. Why is it
important to have a healthy and balanced diet for proper digestion?
14. A healthy and balanced diet is important for proper
digestion because it provides the necessary nutrients, fiber, and fluids that
aid in digestion. It helps maintain a healthy gut micro biome and prevents
digestive problems like constipation or diarrhea.
Q # 15. Describe two
ways in which you can maintain a healthy digestive system.
15. Two ways to maintain a healthy digestive system are:
a) Eating a
variety of fiber-rich foods, such as fruits, vegetables, whole grains, and
legumes, to promote regular bowel movements and prevent constipation.
b) Drinking an
adequate amount of water throughout the day to stay hydrated and support the
digestion and absorption of nutrients.
