Parasitology

Parasitology: the study of parasites and their relationships to their hosts . parasitology has traditionally been limited to parasitic protozoa , helminthes, and arthropods, as well as those species of arthropods that serve as vectors for parasites.
Medical (human) Parasitology consists of medical protozoology , medical helminthology and medical arthropodology .

Human parasitology, an important part of parasitology, study the medical parasites including their morphology, life cycle , the relationship with host and environment. The objectives are to study the way or the measurement of parasitic diseases control.

Parasitism
Parasitism is relationship between two organisms: a paras ite, usually the smaller of the two, and a host, upon which the parasite is physiologically dependent. The relationship may be permanent ,as in the case of tapeworms found in the vertebrate intestine, or temporary, as with female mosquitoes, some leeches, and ticks, which feed intermittently on host blood.
