Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
Megakaryocytes form Thrombocytes ( platelets) which function in the formation of blood clotting

megakaryocyte
Platelets are formed from large cells called megakaryocytes. Megakaryocytes undergo a process called cytoplasmic fragmentation to produce platelets, which are involved in blood clotting.
Platelets are the formed elements that can be described as cytoplasmic fragments. They are crucial for blood clotting and play a role in wound healing and maintaining vascular integrity.

Platelets are fragments of bizarre multinucleate cells called megakaryocytes
Formed Elements
Thrombyopoietin stimulates formation and maturation of megakaryocytes and thereby boosts PTL levels.
Thrombocytes are platelets, derived from fragmentation of megakaryocytes. They are not white blood cells.
