The cell membrane or cell wall.
Phospholipids
Nonpolar fatty acid chains
The lipid bilayer prevents the cell from dissolving in water.

The Cell membrane, along with its integrated proteins. In prokaryotes the Cell membrane is bolstered by the [mostly cellulosic] Cell Wall; in eukaryotes the Cell membrane is bolstered by the [glyco-protein] Cell Coat.

Dust can enter the outer ear, which can be washed just like any other body part. The eardrum prevents dust from entering the middle ear.
It's entering the Urinary system, and when it's entered, it will go r past through the Large and small intenstine .
Cell walls play an important part in maintaining rigidity and supporting structure. For example, if large amounts of water enter the cell, the cell wall prevents it from bursting. This is why animal cell, that lack a cell wall, will burst in this situation.
