Organ: composed of 4 fundamental tissues in a particular way, they can support each other in accomplishment of the organ’s function. System: consists of several organs with related function. Organ and system

Classification of organsHollow/ cavity organs :--layerslumen---studied from inside to outsideParenchymal/Substantial organscapsule--Parenchyma contains cortex and medulla

Classification of organs  Hollow/ cavity organs : -layers -studied from inside to outside  Parenchymal/Substantial organs - capsule -Parenchyma contains cortex and medulla lumen
