The present state of knowledge of heart development is characterized by an enormous discrepancy between the qualitative descriptions of what happens on the organ level and the more or less quantitative information on subcellula

But there are in almost every living organism thousands of cells that die spontaneously by a process which is called with some ambiguity “physiological” or “spontaneous” cell death.
