Splanchnology

Splanchnology is the study of the visceral organs, i.e. digestive, urinary, reproductive and respiratory systems.

[1][2][3][4] The term derives from the Neo-Latin splanchno-, from the Greek σπλάγχνα, meaning "viscera".

More broadly, splanchnology includes all the components of the Neuro-Endo-Immune (NEI) Supersystem.

[5][6] An organ (or viscus) is a collection of tissues joined in a structural unit to serve a common function.

Organs consist of different tissues, one or more of which prevail and determine its specific structure and function.
