Muscular, glandular and epithelial.

Question 6

Muscular tissue is for

Answer 6

Movement via contraction and relaxation of limbs.

Question 7

Glandular tissue is for

Answer 7

secreting substances such as enzymes to enable chemical reactions and hormones to control certain functional features of an organism.

Question 8

Epithelial tissue is for

Answer 8

Covering certain parts of the body(skin).

Question 9

Tissue in the stomach

Answer 9

Muscular(churn contents and break up food), glandular(produce digestive juices) and epithelial(cover the outside and inside of stomach).

Question 10

What does the digestive system do?

Answer 10

Enzymes breakdown food into soluble products we can absorb from the digestive system.

Question 11

Name three insoluble molecules

Answer 11

Proteins,starch and carbohydrates.

Question 12

Name three soluble molecules

Answer 12

Amino acids, sugars and fatty acids.

Question 13

Name three enzymes responsible for the breakdown of large molecules.

Answer 13

Protease enzymes.
Carbohydrase enzymes.
Lipase enzymes.

Question 14

What does protease convert molecules into?

Answer 14

Amino acids.

Question 15

What does carbohydrase convert molecules into?

Answer 15

Sugars.

Question 16

What does lipase convert molecules into?

Answer 16

Fatty acids and glycerol.

Question 17

Organs involved in the digestive system

Answer 17

The mouth.
The oesophagus.
The stomach.
The liver.
The gall bladder.
The pancreas.
The small intestine.
The large intestine.

Question 18

The salivary glands produce

Answer 18

Amylase which can breakdown carbohydrates.

Question 19

The oesophagus helps digestion by

Answer 19

Moving the food along.

Question 20

The stomachs role in digestion is…

Answer 20

To churn up food and break it down into smaller molecules. It produces the acid which the enzyme pepsin works best in.

Question 21

The livers role in digestion is to produce

Answer 21

Bile which neutralises the stomach acid and emulsify oils/fats.

Question 22

The gall bladders role in digestion…

Answer 22

Stores bile.

Question 23

The pancreas role in digestion

Answer 23

Produces digestive juices containing the enzymes protease, amalayse and lipase which are released into the small intestine.

Question 24

The small intestines role in digestion

Answer 24

Absorption of soluble food into the bloodstream occurs here.

Question 25

The large intestines role in digestion

Answer 25

Excess water is absorbed from the undigested food, producing faeces…
