Ranula in a sentence as a noun

Dissolved CO2 should more or less match CO2 concentration in breath, so you would not need a visible cranula on the nose. Carbon is not the only thing the body burns, hydrogen too, which makes water which can't be used to measure calories, but because the majority of what we eat has about the same ratio of hydrogen to carbon, measuring CO2 should be enough.
