When you pass a pin through your skin ,the pinhead is literally much bigger than the individual cell for the pinhead to pass through the said cell membrane.So you can guess the pin must torn out some small veins on its way into your skin,not into an individual cell.Moreover there is no blood inside a cell or cell membrane for it to come out.Hope this clears your doubt. (Figure 3.18). Transport of these vital substances is carried out by certain classes of intrinsic proteins that form a variety of transport systems: some are open channels, which allow ions to diffuse directly into the cell; others are facilitators, which help solutes diffuse past the lipid screen; yet others are pumps, which force solutes through the membrane when they are not concentrated enough to diffuse spontaneously.
