| 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. Many species of leech are haemophagic parasites, living on occasional meals of blood obtained by attaching themselves to fish, amphibians (frogs etc.), and mammals. The medicinal leech, Hirudo medicinalis, which is native to Europe, has been used for clinical bloodletting for thousands of years. ...

The imidazole side chains of histidine and the relatively neutral pK (ca 6.0) mean that relatively small shifts in cellular pH will change its charge. ...

| 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. ...
