Toxins in Biological Definition

Liver

... from the digestive tract, so that the liver can process the nutrients and toxins extracted from food. The hepatic veins drain directly into the inferior ... as protein C , protein S and antithrombin . The liver neutralizes toxins , most medicinal products, and hemoglobin . The liver converts ...

Mycology

... cerevisiae and Schizosaccharomyces pombe . Many fungi produce toxins , antibiotics , and other secondary metabolites . For example, the cosmopolitian (worldwide) genus Fusarium and their toxins associated with fatal outbreaks of alimentary toxic aleukia in humans ...

Antibody

... mark them for ingestion by macrophages. Together with the plasma component complement , antibodies can kill bacteria directly. They neutralize toxins by binding with them. It is important to note that antibodies cannot attack pathogens within cells, and certain viruses "hide" inside cells for ...

Antigen

... surface in the complex with class I histocompatibility molecules . If cytotoxic CD8 + T cells recognize them, they begin to secrete different toxins that cause the lysis or apoptosis of the infected cell. In order to keep the cytotoxic cells from killing cells just for presenting normal ...

Digestion

... intestine, after which food is passed to the large intestine . Blood which has absorbed nutrients passes through the liver for filtering, removal of toxins and help processing of nutrients. In the large intestine, water is reabsorbed, and leftover waste is excreted by defecation . Digestive ...

Herpetology

... in the role of amphibians as long-range ecological warning devices (their decline worldwide is the subject of much study) and the use of the toxins of some amphibians and venoms of some snakes in human medicine. See also Important publications in herpetology External links Center ...

Ion channel

... conduction across the synapses , channels are especially prominent components of the nervous system . Indeed, most of the offensive and defensive toxins that organisms have evolved for shutting down the nervous systems of predators and prey (e.g. the venoms produced by spiders, scorpions, snakes, ...

Muscle

... receptor, and its related condition Lambert-Eaton myasthenic syndrome (LEMS). Tetanus and botulism are bacterial infections in which bacterial toxins cause increased or decreased muscle tone, respectively. The myopathies are all diseases affecting the muscle itself, rather than its nervous ...

Nervous system

... system that animates "animals" ( sponges are an exception). Chemicals that target the activity of nerves generally are the most rapidly acting toxins , typically causing paralysis and/or death. Contents showTocToggle("show","hide") 1 Anatomy 2 Vertebrate nervous systems ...

Nutrition

... nutritionists advise against the processing of food where possible, since undiscovered but possibly essential nutrients may be thereby removed, or toxins may be added or produced through processing and high temperature cooking. Also processing can replace some of the mechanical/biochemical body ...

Vaccine

... - certain bacteria have outer coats that inexperienced immune systems don't recognize. By linking these unknown outer coats to proteins and toxins that reliably provoke an immune response Subunit - rather than introducing a whole inactivated or attenuated micro-organism to an immune system, a ...
