The largest Toothed whale is the Sperm Whale (Physeter macrocephalus) at an average length of 11-16m with a jaw equal to around 25% of it's length. It's possible therefore that a human being could be swallowed whole by a Sperm whale. It's unlikely that any of the other toothed whales (the Orca or the Beaked whales, etc.) would be large enough to swallow an adult human.
Remember, of course, that it is extremely unlikely that a human WOULD get swallowed by a Sperm whale, due to the fact they are distributed around 1000m below the water, can spend long times submerged and travel long distances at great depth. There is not even that much footage of the Sperm whale - let alone the opportunity for someone to get swallowed by one!
oops, sorry! this was supposed to be a reply to someone else's comment. hope it helps though. :)
There is no whale that can swallow a human, even an orca. A blue whale's throat is about the size of a small grapefruit, they feed on krill, shrimp like animals.
Less than a minute-- there wouldn't be enough oxygen to breathe (unless you were wearing a scuba tank) and the acids in its stomach would cook you pretty quickly.
Just as an experiment, to see the effects of stomach acids--- pour a glass of Coca-Cola and drop in a small piece of fresh beef liver. The liver will be broken down VERY quickly-- and Coke is much less acidic than the acids in our stomachs.
(its also why bile burns so much when we throw up; the acids irritate the lining of our throat.)
