Bacteria, pollen, and transplanted tissue are examples of Foreign antigens.
- The source of foreign antigens is external to the body. Examples include components of or compounds created by viruses, microorganisms (such as bacteria and protozoa), substances in snake venom, specific proteins in meals, pollens and serum and red blood cell components from other people.
- T cells only identify foreign antigens that are present on the surfaces of the body's own cells, as opposed to immunoglobulins, which interact with infections and their harmful products in the extracellular spaces of the body.
- These antigens may come from pathogens that proliferate inside of cells, such as viruses or intracellular bacteria, or they may come from pathogens or their byproducts that cells have ingested through the process of endocytosis.

A burning liquid that is pouring over the edge of a container is known as a three dimensional fire.
<h3>What is a
three dimensional fire?</h3>
A liquid fuel fire that is discharged from an elevated or pressured source, forming a pool of fuel on a lower surface, is referred to as a three-dimensional fire. Fires that are flowing in three dimensions cannot be controlled using foam.
The best extinguishing agent for pressured liquid and three-dimensional flowing liquid fires is dry chemical. In many large spill fires if impediments are present in the spill location, they are also favored.
