Location: The thymus is located in the top part of the chess, under the breast bone and between the lungs

Location: The red bone marrow is found within the flat bones of the body

Function: It is in charge of making red blood cells, white blood cells as well as platelets.

Location: The spleen is located inside the lefty rib cage, above the stomach

Function: The spleens function is to clean the blood and remove aged or defective red blood cells, place were the lymphocytes can be activated as well as cloned, can store platelets,monocytes and irons

Location: There are multiple lymph nodes through out the body they are located in the neck, armpits, groin, around the gut and in between the lungs

Function: It cleans the lymph (body fluid) as well as begin a site for the activation and cloning of lymphocytes

Location: They are located at the back of the mouth, and to the sides of the pharynx

Function: The tonsils function is to prevent germs and bacteria from entering the mouth or nose and overall the body

Function: The appendix acts as a store house for good bacteria

Location: The appendix are located on the lower part of the abdomen

Location: The MALT structure is located in the gastrointestinal tract, nasopharynx, thyroid, breast, lung, salivary glands, eye and skin

Function: Surveillance of the materials found within the digestive system for pathogens

This is the defense system we are born with, hence the word natural

The adaptive immune system is created in response to exposure to pathogens

The Innate immune defense is also known as the non-immune defense does not attack any specific pathogen and rather any pathogen that enters or tries to enter the body

The adaptive immune defense also known as the specific immune defense will attack specific pathogens

In the innate defense system is composed of two first lines of defense meaning that it uses both physical and chemical barriers

Due to the fact that it is specific the response will take longer

It is composed of the third line of defense and subdivides into humoral immunity and cell-mediated immunity

In this defense there is the production of memory cells for future attacks

The antigen can also be a self antigen meaning that it is a antigen who is part of are bodies tissue cells, the bodies tell the immune system that these cells are ours and should not be attacked in any way

Description: A antibody also called immunoglobulins are proteins that are secreted by plasma cells in order to attack pathogens

They are able to bind to specific antigens who were detected by the B cells

It has a Y shape with 4 polypeptide chains, a antigen binding site at the end of each arm

The simplest mechanic defense system in which the antibody blocks specific sites of the pathogen, this doe not allow for the antigen to bind to any tissue cells receptor

When a antibody crosses with an antigen and from these clump like structures, this way enchaining phagocytosis

The formation of insoluble complexes as a result between a cross of antigens and soluble molecules, this makes it easier for other cells to engulf the complex

The antibodies blocks the antigens binding site, this can lead to cell lysis or and enhances inflammation and phagocytosis

There are both present in Artificial and Passive humoral immunity

Artificial active immunity occurs when the body produces antibodies in response to a vaccine that contains weaken pathogens itself

Natural active immunity occurs when the body produces antibodies in response to a viral or bacterial infection

Artificial passive immunity occurs when a person is injected with a serum such as gamma globulin in which it already contains antibodies

Natural passive immunity occurs when the bodies receives antibodies through natural means such as the mothers breast milk or through placenta for fetuses

Its function is to destroy pathogens while also aiding in facilitating healing and repair. The monocyte also can morph into a macrophages

The macrophages are able to sense pathogens and eventually destroy them through engulfing the pathogen, the cell can also secrete inflammatory agents as well as the activation of other cells such as neutrophil. This cell also serves as a antigen-presenting cell

They patrol the body for any pathogens, when found they will trap them and kill them and can activate other cells such as macrophages

This cell is able to patrol and detect pathogens, this way helping to destroy these coming pathogens as well as activation of other cells such as neutrophil

The cell kills any cells that are infected with a pathogen to prevent the spread

They are effector cells that defend the body through attacking pathogens such as parasites

These cells take in the pathogen, they process it and present the antigen to other cells for activation

They help control other cells and attack pathogens such as parasites

Cells that are yet not active, but one they are, they will morph into a Helper T cell

The helper T cell will be activates by a Antigen presenting cells and itself will activate cells such as the Killer T cells as well as the B cell

A virgin killer T cell is a T cell that has yet to be activates, one it is it will morph into a Killer T cell

The killer T cell also known as the cytotoxic T cells attack the pathogens directly, after the attack

These cells contain the memory of the attack, so when the same pathogen attacks the body it will be able to react quicker as it already knows how to kill it

They are activated by the Helper T cells, they also serves as antigen presenting cells and when activated will morph into a plasma cells

They are cells that are yet not activated but once they are they will morph into a B cell

They are the result of a plasma B cell morphing, they will produce antibodies to attack the specific pathogen

They are the result of a plasma B cell morphing they provide long lasting protective immunity

The result of the B cells morphing after the attack, they store information for future attacks and helps for defense against specific pathogens
