Q

Glands in the digestive system include:

A
  1. the salivary glands
  2. the gastric glands (located in the stomach lining)
  3. the liver (the gallbladder stores fluids from the liver until they are released into the digestive tract)
  4. the pancreas
  5. the intestinal glands (located in the lining of the small intestine)

Q

Absorption of nutrients

A

This is when the nutrients move through the
lining of the digestive tract into the blood or
lymph.
Mostly occurs in small intestine which contain
folds called VILLI. The villi have blood and
lymphatic vessels through which nutrients
flow through the body

17
Q

Mechanical transformation of food

A

Food is physically broken down into smaller substances to prepare for chemical transformations

Chewing(teeth used to crush and grind food)

Churning (muscle contractions with mix food withsecretions from digestive system…in stomach andsmall intestine)

18
Q

Organs and glands responsible for the chemical transformation of food

A

Salivary gland (saliva)

Gastric glands (gastric juice)

Intestinal glands (intestinal juice)

Pancreas (Pancreatic juice)

Liver (Bile)

19
Q

Salivary glands

A

produce saliva which breaks down starch

20
Q

Identify

Refers to the muscular contractions of
esophagus, stomach, small and large
intestines that move substances through the digestive tracts

A

peristalsis

21
Q

What is

The organ that stores bile

A

The Gallbladder

22
Q

Chemical transformation

A

The digestive tract breaks down the complex
molecules of food into simple molecules. There
is much help of secretion from digestive glands
during this process
