| Hirudinea |
The leeches are annelids comprising the subclass Hirudinea. There are freshwater, terrestrial and marine leeches. Like their near relatives, the Oligochaeta, they share the presence of a clitellum.

Histocompatibility is the property of having the same, or mostly the same, alleles of a set of genes called the major histocompatibility complex.

| histogenesis |
Histogenesis[ h?tō j?nəssiss ] is the formation of tissues and organs from undifferentiated cells. The cells form organs during the fetal phase (9th week to birth) of pregnancy. The layers of cells that form these organs are formally called the Primary Germ Layers, or PGL. The innermost layer is termed the endoderm which may form the lungs, kidneys, and most of the glands in the human body. ...
