The cell membrane controls the passage of substances into and out of the cell. It is a selectively permeable barrier made up of a phospholipid bilayer with proteins embedded in it. It allows some material (such as steroid hormones) to pass straight through, while others (such as ions) need the assistance of a protein transporter, and some material cannot get in at all.

What is the sphincters function?
They are variable controls which can open to allow the passage of material and then closed to prevent further passage of materials. If you didn't have an anal sphincter you'd really have problems.
