Anatomical terminology

Splanchnic (Ancient Greek: σπλαγχνικός splanchnikos; from σπλάγχνον splanchnon, mostly found in its pl. form σπλάγχνα splanchna, "inward parts,[1][2] organs"[3]) is usually used to describe organs in the abdominal cavity (visceral organs).[4] The term "splanchnologia" is used for grouping in Nomina Anatomica,[5] but not in Terminologia Anatomica. It includes most of the structures usually considered "internal organs", but not all (for example, the heart is excluded).[5]

More specifically, it can also refer to:

The splanchnic organs include the stomach, small intestine, large intestine, pancreas, spleen, liver,[8] and may also include the kidney.[9] Intense endurance exercise has been shown to reduce blood flow in the liver and small intestine, but not in the kidney or large intestine.[9]
