Question 9

Chemical digestion the definition

Answer 9

The process of making large insoluble molecules into smaller more soluble thru hydrolysis

Question 10

Hydrolysis

Answer 10

The breaking down of food by hydrolysis due to the add of water

Question 11

Hydrolases

Enzymes

Question 12

How do hydrolases work

Answer 12

Good to active site
Active site breaks down due 2 h20
Food then moves on

Answer 14

Protein to professes to polypeptides to professes to amino acids

Question 15

Digestive sequence of fats

Answer 15

Large fat globule to bile salts to smaller fat droplets to lipases to glycerol and fatty acids

Question 16

Where does most absorption occur

Answer 16

The small intestine

Question 17

Why is the small intestine suited for absorption

Answer 17

Walls=transverse folds
Have villi
Villi have micro villi

Question 18

What is the functions of villi

Answer 18

Secretes mucus
Increase SA
Rich Mito one cell thick
Lots blood and lymph

Question 19

Goblets cells secrete what

Answer 19

Mucus

Question 20

How are glycerol molecules absorbed

Answer 20

Water soluble goes straight into villi joins with the altered fatty acids and forms chyle (hepatic portal vein)

Question 21

How are fatty acids absorbed

Answer 21

Water insoluble so combined with bile salts to become soluble enters villi and joins with glycerol to form chyle (hepatic portal vein)

Question 22

Where does the chyle go to

Answer 22

Go from the lymph system to the capillaries surrounding the heart

1 from birth not curable

2 for. Bad diet and lack of exercise can be cure

Question 26

Structure of villi

Answer 26

Columnar epithelium small artery 
Goblet cells  small vein 
Lacteals    Lymph vessel 
Arteriole   Micro villie 
Venule

Question 27

Assimilation in the liver

Answer 27

Liver converts glucose into glycogen removes bad stuff
Then back when blood sugar too low break hormones
Excess amino broken to urea
