A

RUGAE

26
Q

A

ABSORBTION

30
Q

What is ASSIMILATION?

A

It is where the movement of digested food molecules into the cells of the body where they are used.

31
Q

It is considered as organ of complete digestion and absorption. Because it secretes the enzymes that change food materials into their simplest components. It is also the longest organ of the digestive system.

A

SMALL INTESTINES

32
Q

What are the 3 different sections of the Small Intestine called?

A

a. Duodenum (25 cm)
b. Jejunum (2.5 m)
c. Ileum (3.5 m)

33
Q

A.K.A colon an organ after the small intestine.

A

LARGE INTESTINE

34
Q

What are the functions of the large intestine?

A

a. temporary storage of fecal materials.
b. absorbs vitamins.
c. reabsorbs water from undigested residue.

35
Q

It is where the body expels waste products from digestion through the rectum and anus.

A

EXCRETION

ASSIMILATION
EXCRETION

37
Q

It is where the complications are directly related to the type of nutrient not being absorbed. Digestive System needs Vitamins to function properly. Vitamin D rich food such as egg yolks, saltwater fish, liver and fortified milk and cereal.

A

Nutrient Deficiency

38
Q

What can Vitamin B-12 deficiency affect?

A

Vitamin B-12 deficiency can affect the digestive tract.

39
Q

It is when the body has trouble digesting food and absorbing nutrients.

A

Malabsorption

40
Q

It helps break down polysaccharides (cellulose) and other foods that human body cannot digest. Beneficial bacteria also help the body re-absorb excess water from the large intestine, and they break down carcinogenic drugs and chemicals that are incorporated in the food.

A

Probiotics-

41
Q

What are ANTIOXIDANTS?

A

They are naturally occurring compounds that have
the ability to neutralize unstable free radicals that can cause
cellular damage.

Q

These nutrients that are needed by the body in small quantities to promote growth and maintenance of health and life processes.

A

VITAMINS

43
Q

What are MINERALS?

A

inorganic substances, which just like vitamins, are needed by the body in minute quantities or as traces

44
Q

What does GERD stand for?

A

Gastro Esophageal Reflux Disease

45
Q

What is GERD?

A

regurgitation and acid reflux (stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus))

46
Q

-polyps, a growth on the inner lining of the colon or rectum
-sudden weight loss or blood in their stool

A

Colorectal cancer

47

56
Q

Good habits/practices to maintain a healthy digestive system

on the stomach and beneficial in their own
way.

symptoms (for example, laxatives for
constipation).
