Most of Abigail's and Brittany's shared organs are located at or below the level of the navel.[2]
* 2 heads
* 2 completely separate spinal cords
* 2 vertebral columns with ribs bridging the two columns; their coccyxes merge.
* 2 arms (originally 3, but rudimentary central arm was surgically removed, leaving central shoulder blade in place)
* 1 broad ribcage, with surgery to correct scoliosis and expand the pleural cavities
* 2 breasts
* 2 highly fused sternums, traces of bridging ribs
* 4 lungs (medial lungs moderately fused, not involving Brittany's upper right lobe); three pleural cavities
* 1 diaphragm with well-coordinated involuntary breathing, slight central defect
* 2 hearts in a shared circulatory system (nutrition, respiration, medicine taken by either affects both)
* 2 stomachs
* 2 gallbladders
* 1 liver, enlarged and elongated right lobe
* Y-shaped small intestine which experiences a slightly spastic double peristalsis at the juncture
* 1 large intestine with one colon
* 2 left kidneys, 1 right kidney
* 1 bladder
* 1 set of reproductive organs
* 2 separate half-sacrums, which converge distally

One could tell when someone was touching the other one...although they said that they couldn't actually "feel" it.
Odd.

* 1 slightly broad pelvis
