Gallifreyan physiology: Difference between revisions

Gallifreyan [[blood]] was different from human blood, darker and with a slight orange tinge to it. ([[TV]]: ''[[The Two Doctors (TV story)|The Two Doctors]]'', [[PROSE]]: ''[[The Left-Handed Hummingbird (novel)|The Left-Handed Hummingbird]]'', ''[[Vampire Science (novel)|Vampire Science]]'') The differences were readily apparent under a [[microscope]]. ([[TV]]: ''[[Spearhead from Space (TV story)|Spearhead from Space]]'', ''[[The Invisible Enemy (TV story)|The Invisible Enemy]]'', ''[[Doctor Who (TV story)|Doctor Who]]'') It was highly adaptive, with regenerative properties. ([[PROSE]]: ''[[The Art of Destruction (novel)|The Art of Destruction]]'') Gallifreyan blood had [[temporal platelet]]s, allowing for a more "ad-hoc" recovery from injury not serious enough to require [[regeneration]]. ([[AUDIO]]: ''[[The Bride of Peladon (audio story)|The Bride of Peladon]]'') It didn't have the same A and B types as human blood (i.e., the A and B antigens were not present), but different blood types still existed with [[Romana II]] noting that her blood was not compatible with the [[Fourth Doctor]] when he was badly injured by [[vampire]]s, requiring him to receive a transfusion from his [[Eighth Doctor|future self]]. ([[PROSE]]: ''[[The Eight Doctors (novel)|The Eight Doctors]]'') The extra-cellular matrix was incompatible with [[Earth]]-based life and the structure of [[haemoglobin]] was different. ([[PROSE]]: ''[[The Art of Destruction (novel)|The Art of Destruction]]'', ''[[Placebo Effect (novel)|Placebo Effect]]'', [[TV]]: ''[[The Invisible Enemy (TV story)|The Invisible Enemy]]'') The Tenth Doctor explained to [[Christina de Souza (Keeping up with the Joneses)|Christina]] that fried bread would clog arteries, but he had "tiny things" inside his blood that "sluice[d] it out again." ([[PROSE]]: ''[[Keeping up with the Joneses (short story)|Keeping up with the Joneses]]'')

Accounts differed as to the vascular systems of Gallifreyans in their first incarnation. Some accounts indicate that Gallifreyans normally had two hearts even in their first body. ([[AUDIO]]: ''[[Frostfire (audio story)|Frostfire]]'', [[PROSE]]: ''[[Time and Relative (novel)|Time And Relative]]'', [[TV]]: ''[[The Doctor's Daughter (TV story)|The Doctor's Daughter]]'') Other accounts indicated that Gallifreyans [[Loom]]ed after the [[Pythia's curse]] of sterility originally emerged with a single heart and gained their second only after their first [[regeneration]], ([[PROSE]]: ''[[The Man in the Velvet Mask (novel)|The Man in the Velvet Mask]]'', [[AUDIO]]: ''[[Time in Office (audio story)|Time in Office]]'') while those of [[Newblood]] houses sprang from the Looms with two hearts from the outset.
