Q

intergumatnyr system

A

17
Q

The small intestine is an organ of the digestive system. Its role is to absorb the nutrients from broken-down food as it passes through the digestive system. Cells lining the small intestine arrange into ‘finger-like’ projections to increase surface area. Briefly outline why the cells are arranged like this.

A

These cells are arranged to maximise their surface area to volume ratio which allows for greater absorption of nutrients from food into the cells.

18
Q

Tissue

A

group of cells that work together to carry out a specific function

19
Q

Organ

A

ompoed if multiple tissues to perform a specalised task

20
Q

Organ system

A

several systems that work together

21
Q

Organism

A

a living body that carries out critical functions such as growth and reproduction

22
Q

where do organisms not function

A

in isolation eg. organs that form larger systems

23
Q

why are vascular tissue arranged in vascualr bundles

A

to branch out to form veins
