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.
Protists are one-celled organisms. Symbiotic protists are protists that live with other larger organisms in a mutually beneficial relationship. The anaerobic parabasalid species of protist is an example. Photosynthetic protists are the protists that process sunlight. The dinoflagellates Noctiluca and Pyrocystis are examples of this type of protist. There are also protists that serve both purposes: they are both symbiotic and photosynthetic. The protists zooxanthellae are an example of this type of protist.
