The lymphatic system is a network of low-pressure vessels which provide a route for the return of interstitial fluid to the blood vascular network. disease. Due to the complexity of that system, the demonstration of an adaptive immune system in prokaryotes was a surprise. An adaptive immune response is set in motion by antigens that the immune system recognizes as foreign. Our mission is to provide a free, world-class education to anyone, anywhere. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system, or humoral immunity versus cell-mediated immunity.

Viral replication: lytic vs lysogenic. If pathogens pass the non-specific first line of defence, they will cause an infection. The immune system is responsible for the specific defense against agents, called antigens, which are foreign or harmful to the body. • The defence proteins are called antibodies, if the target is a pathogen, • An antitoxin if the target is a poisonous chemical. The immune system refers to all of the cells, tissues, organs and processes that protect an organism from invasion by pathogens. Acquired, or adaptive, immunity is a second immune defense system and develops slowly after exposure to an initial infection. In humans, the blood-brain barrier, blood-cerebrospinal fluid barrier, and similar fluid-brain barriers separate the peripheral immune system from the neuroimmune system, which protects the brain.
