31
Q

What is physical digestion?

A

Breaking food into smaller pieces, increases the surface area for enzymes to better do their job

32
Q

What is chemical digestion?

A

Using enzymes and acids to further break large molecules into smaller ones to be more easily absorbed in the small intestine

33
Q

What does the stomach do?

Hold faeces before removal

40
Q

What does the anus do?

Brick red but blue for everything else

43
Q

What colour does Biuret turn with protein?

A

Purple with protein, blue otherwise

44
Q

Why does digestion keep us alive?

A

Glucose combined with oxygen in cells to produce energy in respiration for living processes like movement. Fat provides long term energy supply. Protein for growth and repair.

45
Q

Where do the two heart pumps pump to?

A

The lungs and the body

46
