Q

How we digest food

A
  1. Ingestion
  2. Food is being broken down and mixed with saliva > via esophagus secretion
  3. (Stomach) acid coming from the gastric glands gets mixed with the food
  4. (Chyme) Exits the stomach and goes to the
  5. Small Intestine (the major organ for digestion and absorption)
  6. Further absorption occurs in the Large Intestine
  7. Undigested materials are brought to the rectum (where they are stored until they are ready to)
  8. Exit the body through the anus

Major Function of Small Intestine

A

Absorption of nutrients

18
Q

3 parts of Small Intestine

A
  1. Duodenum
  2. Jejunum
  3. Ileum
19
Q

The portion of the digestive tract extending
from the ileocecal junction to the anus

A

Large Intestine

20
Q

4 parts of the Large Intestine

A
  1. Cecum
  2. Colon
  3. Rectum
  4. Anal Canal
21
Q

-is the largest organ of the body
-It consists of 4 lobes

A

Liver

22
Q
  • a fluid important for digestion
  • produced by the liver
A

Bile

23
Q

a small sac on the inferior surface of the liver
that stores concentrated bile

A

Gall bladder

24
Q

During digestion, It produces enzymes and
secretion of buffers to increase the PH of the fluid
secreted from the stomach.

A

Pancreas

25
Q

It receives almost completely digested food from the cecum, absorbs water and nutrients, and passes waste (stool or feces) to the rectum

A

Colon

26
Q

It absorbs large volumes of water and electrolytes, and the microbial digestion of soluble and insoluble carbohydrates

A

Ceucum

27
Q

Undigested materials are brought to the _________ where they are stored until they are ready to exit the body through the _________

A

Rectum, Anus

28
Q

Process where complex molecules like proteins, fats, and carbohydrates are broken down into smaller pieces that your body can use

A

Chemical Digestion

29
Q
