It allows water to pass through
It allows other small molecules to pass through
Why is passing faeces NOT considered excretion?
It is not metabolic waste
It has not passed through the kidneys
It is not waste
It has not been made in the body
What is common to many metabolic waste compounds?
They contain nitrogen
They contain glucose
They contain carbon dioxide
They contain starch
Why are the tubules of the kidney so long?
To create a large surface area for reabsorption
