Digestion
Absorption
Elimination
What do you call a process of putting food into your mouth?
Ingestion
This refers to the breakdown of food into small molecules that can be used by the body?
Digestion
What process happens after food is broken down into small molecules in the digestive system?
Absorption
What happens to substances that cannot be absorbed by the body, and in what form are they removed?
They are eliminated as feces.

mechanical digestion
This is the rhythmic, involuntary contraction of smooth muscles is called?

This refers to the break down of food into simpler nutrients that can be used by the cells?
Chemical digestion
What facilitates chemical digestion?

This is a fluid produced by cells that line the stomach?
Digestive juice
Composition of the digestive juice?
hydrochloric acd (HCI)

liver
The organ that is responsible in storing the broken down fats coming from the liver?
gallbladder
What are the folds in the lining of the small intestine called?
Villi
They are tiny, hair-like projections on the surface of the villi in the small intestine. They increase the surface area for absorption, allowing for more efficient uptake of nutrients from digested food into the bloodstream.
Microvilli
This is a part of the digestive system responsible for absorbing water from undigested food and forming solid waste for elimination?
Large intestine
What do you call the undigested material that eventually forms into a solid mass?
feces
What contains the feces?
Undigested fiber from plant foods, dead bacteria and traces of undigested fat and protein.
This serves as a storage site of feces before it is eliminated?
Rectum

Anus
What are the common ailments and disorders of the digestive system?
Diarrhea
Constipation
Gastroesophageal reflux disorder (GERD)
Gallstones
Peptic Ulcer
Colorectal cancer
This is characterized by loose and watery stool and frequent bowel movement?
Diarrhea
Prolonged diarrhea may lead to?
Dehydration
A compact, dry, and hard stool characterizes?
Constipation
A person who is constipated experiences difficulty in?
Defecating
This occurs when the acid from the stomach flows back to esophagus?
Gastroesophageal reflux disorder (GERD)
These are stones or lumps that build up in the gallbladder. These stones are hardened cholesterol and pigments in the bile?
Gallstones
A sore or painful wound in the lining of stomach and small intestine is called?
Peptic Ulcer

This occurs when tumors form in the lining of the large intestine?
Colorectal cancer

This is the process of eating the right food that your body needs so you can grow properly and healthy?
Nutrition
They are professionals who advise and plan matters on food and nutrition? They develop dietary plans and guidelines to help people make healthy food choices?
Nutritionists
What are the nutrients that food contains?

proteins
vitamins
minerals
water

rice and bread
A nutrient that protects the body organs and insulate the body?
fats
A nutrient that supply raw materials for growth and repair of the body?
proteins
Nutrients that help regulate body functions?
vitamins and minerals
This helps you to keep hydrated and regulate body temperature and maintain body functions?
water
Some ways to prevent food contamination?
a. Wash your hands thoroughly before and after eating.
b. Wash eating and cooking utensils before and after using them.
c. Wash fruits and vegetables before eating them.
d. Avoid street foods. Make sure that the food preparation is clean.
e. Handle and prepare food well before cooking or putting them in the refrigerator.
Give some examples of good eating habits?
Chew food well and avoid swallowing large chunks of food.
Eat in moderation.
How does regular exercise helps in your digestive system?
