Sepsis Overview. Sepsis is a condition in which the body is fighting a severe infection that has spread via the bloodstream. If a patient becomes septic, they will likely have low blood pressure leading to poor circulation and lack of perfusion of vital tissues and organs.epsis Overview.

Many are minute: The green alga Nanochlorum is only 0.01 mm (0.0004 in) long. Giant kelps can grow to 65 m (210 ft) or more in length. Some protists form structures known as. that are resistant to chemicals and drying and that disperse in the environment.Spores are often the infectious stage of organisms that cause diseases in humans when ingested.ecause the Protista are so diverse in form, classification within the kingdom has proved difficult. The classification of the Protista is currently based largely on the structure and organization of the cell, the presence of organelles, and the pattern of reproduction or life cycles.
The Protista, or Protoctista, are a kingdom of simple eukaryotic organisms, usually composed of a single cell or a colony of similar cells. Protists live in water, in moist terrestrial habitats, and as parasites and other symbionts in the bodies of multicellular eukaroytes.ome lack mitochondria and suggest what the first eukaryotes may have been like, while others have primitive mitochondria that closely resemble bacteria. Some basal Protista without mitochondria are Trichomonas, a vaginal parasite of humans; Giardia, an intestinal parasite; and Entamoeba, the cause of amoebic dysentery.
