How does the TSA continue to function despite the 4th amendment?

The fourth amendment protects from unreasonable search and seizure and yet the TSA can take your liquids if they're not clear and are larger than a certain size, can pat you down, you have to go through the body scanners, etc. How are these not considered a violation of the 4th amendment?

Note: I'm not necessarily against these precautions, however I don't see how they're constitutional.

>The fourth amendment protects from *unreasonable* search and seizure

The lower courts have decided that what the TSA is doing is *reasonable*, and the Supreme Court hasn't said otherwise.  The lower courts think it is reasonable because previous events have shown that air travel can be a danger to individual and national security, and the elevated precautions have become necessary.
