Respiratory bypass system

From Tardis Wiki, the free Doctor Who reference

A respiratory bypass system was a part of Gallifreyan physiology which allowed Time Lords to go without breathing for longer periods of time than most humans could. (BFA: Return of the Krotons) It also allowed them to filter out unpleasant smells. (NA: Cat's Cradle: Witch Mark)

The Doctor used it to survive on many occasions. The Doctor's fourth self used his respiratory bypass system to survive being strangled by an Osirian service robot. (DW: Pyramids of Mars) He later used it to avoid inhaling helium. (DW: The Robots of Death) The fifth incarnation used it to survive brief exposure to the vacuum of space (DW: Four to Doomsday) as well as to survive being hanged. (ST: A Town Called Eternity) His sixth persona was able to avoid hypoxia when he shut down atmospheric controls to the mines on the planet Onyakis in order to defeat the Krotons there. (BFA: Return of the Krotons) In his seventh body, the Doctor used his respiratory bypass system to avoid being overcome by ether. (NA: Timewyrm: Genesys) His eleventh incarnation survived the vacuum of low earth orbit long enough to find and put on an impact suit -- backwards. (DW: The Doctor, the Widow and the Wardrobe)

At least one human may have developed such a system: Timothy Dean, who gained one when he became infected with the Seventh Doctor's DNA. (NA: Human Nature)
