Swallow the saliva in your mouth cavity and immediately afterwards try to swallow again and again. You will probably find it difficult to swallow the second time and even more difficult the third time. Why do you think this is?Now drink a glass of water and note that you have no difficulty swallowing in rapid succession.Explain the differences.

really never thought about it, or tried it. But Im sure if you have water going down it would be easier.

well i guess it has to do with the fact that it takes a while to salivate. after swallowing, that bit of saliva is gone, so the salivary glands need a little more time to produce, hence it is harder to swallow right after. SALIVA & SWALLOWING GO HAND IN HAND!
in terms of the water, it wouldnt be any difficulty as the water is water, it would do with the saliva could do on a larger scale mainly because our body didnt have to produce it!
[I mean some saliva is needed to help the water flow, but u catch my drift!]

You swallow all of it the first time. The second or third time (if you're trying to do it quickly) there is almost no saliva left. No saliva means no lubrication and nothing to swallow.

The salivary glands in your mouth produce saliva which, (acts as a lubricant,) and allows you to swallow easier.
If you eliminate the lubication, it becomes more diffucult to move because of friction.
The water you drink allows you to continue swallowing because it reduces friction.
(it is a guess?)
