Interferons
Activated by lymphocytes, Polymorph phagocytes absorb or envelope mostly bacteria, compartmentalize it, barrage it with enzymes attempting to destroy it, or radically alter it. Macrophages injest and destroy a wider variety of invaders, including viruses, and act as anitgen presenting cells which serve to increase immune response. Some epithelial and reticular cells also act as phagocytes in that the can injest and destroy or remove invaders.
memory B cells
Proteolytic enzymes will destroy the cells that produced them if they are produced in an active form. To protect the body's own cells these enzymes are secreted in an inactive form into the digestive tract and activated where they are needed.

I believe the hormones are released from the adrenal gland: hydrocortisone and corticosterone.
it doesnt.........
It's "activated". Having activated the alarm to protect against robbers, he left the building.
The macrophages are defense cells that help to protect the body from debris and invaders. They stay among the white blood cells
Directly through the bacteriophagic function by macrophages, lymphocytes etc and indirectly by immunity

macrophages can be considered one of the many "defenses" that work to help protect our immune system. they do have a special role. they engage in phagocytosis which is the process in which a macrophage engulfs cellular debris or dead cellular material and pathogens. the material goes into the internal part of the macrophage (vacuole) it then travel to the lysosomes where the waste is broken down and it then the reduced material is released extracellularly or intracellulary. in the case of a pathogen a macrophage will present an antigen for the particular pathogen in order for the immune system to identify it. each antigen has a specific helper T cell for each pathogen.
It uses a special filter canister that usually contains activated charcoal which absorbs all chemicals that enter the filter, leaving clean air to breathe in.

If you are the mother, then it may be related to your baby's natural regressive defensives which are activated when he ornshe sees you. This is normal and will pass in a short time. It is the baby's way of communicating to you to protect it.
The lining has to thicken in order to protect the egg that is released.
