The semantics of this question made me vomit blood.

One day a patient will look me in the eyes and ask, "Where are tripetides broken down?" I will smile at them and say, "the intestinal mucosa and not the duodenum." They'll smile back and I'll walk away and think of this moment as I jump from the window.

After the cuff is tied, the cells and tissue distal to the cuff will continue consuming ATP (ATP->ADP), but no fresh blood will be delivered to โ€œclearโ€ what will be an accumulating amount of ADP and other metabolites. ADP (=Adenosine) is itself a proxy of consumption and drives vasodilation of arteries! (Evolution is smart!) Increasing ADP/Adenosine in a โ€œlocal environmentโ€ is a signal to the body that a lot of consumption is occurring there; thus, arteries and arterioles naturally dilate to increase blood flow rates and โ€œsweep awayโ€ metabolic byproducts.

j44n  Its actually a man, there's no DHT to to dev the external genitals. +1
am4140  @monkey - with real anorexia, she wouldnโ€™t necessarily have boobs either. If sheโ€™s got boobs she has the nutrition to develop boobs. That was my thought. +
freckles  the patient is actually what ever gender they want to identify as. If this was a 5 alpha reductase deficiency the patient would have experienced masculinization of external genitalia during puberty when testosterone levels increase significantly. The pt most likely has Androgen Insensitivity Syndrome. +7
weirdmed51  BLIND VAGINAL POUCH = never ever ever in anorexia nervosa! It is an anatomical defect, hence not psych prob. +
