an organ is a tissue group that performs a function.

in the case of say, your small and underdeveloped bicep, you have all sorts of tissues, skeletal muscle, tendon, ligament, vasculature, etc., that all work together to perform a function, specifically in this case, contracting, weakly, your forearm to your shoulder.
