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 plant-like protists are commonly referred to as algae and can be either single-or multi-celled. Algae contain chlorophyll and carry out the process of photosynthesis. Diatoms are single-celled algae that excrete a cell wall made of silica.he animal-like protists are also known as protozoans, which is Latin for 'first animals.' All protozoans are single-celled heterotrophs and are categorized based on their movement. Paramecia are examples of protozoans that use cilia, or tiny hairs, to propel themselves through the water.
