Carotid artery
From Tardis Wiki, the free Doctor Who reference
The carotid artery was a major artery of the neck, related to the body's oxygen supply. The Fourth Doctor gave Jake Abiathar Earl-Thornton a sticking plaster he instructed Jake to place adjacent to the carotid artery, enabling him to breathe on Earth, 50 million years in his future. (PROSE: Earth)
