The remaining nitrite is absorbed into the circulation; in blood vessels nitrite forms vasodilatory NO after a reaction with deoxygenated Hb.
“The remaining nitrite is absorbed into the circulation; in blood vessels (c) nitrite forms vasodilatory NO after a reaction with deoxygenated Hb (deoxy-Hb).”

Approximately 25 % of ingested nitrate is taken up from the circulation and concentrated in the salivary glands and re-secreted into the mouth, where it is reduced to nitrite.
“Approximately 25 % is taken up from the circulation and concentrated in the salivary glands and re-secreted into the mouth, where it is reduced to nitrite (adapted from Lundberg et al.(10) ).”

A proportion of ingested nitrate is converted directly to nitrite by facultative anaerobic bacteria that reside on the dorsum of the tongue during mastication in the mouth.
“A proportion of ingested nitrate (NO 32 , ---Q) is converted directly to nitrite (NO 2 2 , ! ) by facultative anaerobic bacteria, that reside on the dorsum of the tongue, during mastication in the mouth (a); the remainder is swallowed and is rapidly absorbed from the upper gastrointestinal tract.”

The remainder of ingested nitrate is swallowed and rapidly absorbed from the upper gastrointestinal tract.

Some salivary nitrite enters the acidic environment of the stomach where NO is produced non-enzymically from nitrite after formation of nitrous acid and then NO and other nitrogen oxides.
“Some of the salivary nitrite enters the acidic environment of the stomach once swallowed (b), where NO is produced non-enzymically from nitrite after formation of nitrous acid (HNO 2 ) and then NO and other nitrogen oxides.”

The NO generated in the stomach kills pathogenic bacteria and stimulates mucosal blood flow and mucus generation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
