Although malaria is usually considered to be the most important and well-known infection, there are other organisms that also cause human infection including Babesia spp., Leishmania spp., Trypanosoma spp., and various filarial worms.

The heart is one of the first organs in an embryo to develop, and the first to be functional. In humans, heart beat starts early during the third week of development (postfertilization), to generate a unidirectional blood flow by the end of this week. The heart develops as a specialized...
Nephridia are tubular structures that filter body fluids other than blood, found in flatworms, annelids, and many other invertebrates. Beating cilia or flagella draw fluid into the tubular system, leaving cells and proteins behind in the tissues. The tubules then reabsorb useful substances such ...
In this work we focus on one key schistosome species infect- ing humans, Schistosoma mansoni; we examine extracel- lular and intracellular enzymes of these worms that are involved in the metabolism of riboflavin (vitamin B2) and its key metabolites, flavin mononucleotide (FMN) and flavin adenine...
Are pinworms part of the phylum Platyhelminthes? Are members of the phylum Platyhelminthes acoelomates or coelomates? Do members of the phylum Nematoda have a hydroskeleton? Segmented worms are classified in which phylum? Are members of the phylum Platyhelminthes parasites in humans?
