Corticosteroids act on the immune system to:
They act as an antiseptic to your eyes, they protect it from bacteria.
The lymph system and the nodes act as a filter.
Yes.
A cytokine is a regulatory protein released by a cell in the immune system. Cytokines act as intercellular mediators when the body is generating an immune response.
They have enzymes in them to kill pathogens
cortisole i guess you mean which is secreted from adrenal its not a part of immune system but it has a permissive act in immunity
Any sort of "foreign" substance can, and most often will, elicit an immune response under certain curcumstances--provided the immune system is healthy. This would include bacteria, viruses and fungi. Related: An unhealthy, or compromised immune system can act in all sorts of undesirable ways, ranging from low response to threat or injury to actually creating antibodies to attack its own system or other organs and tissue.
Macrophages act as phagocytes (engulfing antigens) and digest them for specific defense of immune system to detect. They are non-specific, therefore, they just digest and excrete antigens.
An antigen is a substance that can invoke an immune response. While an antibody is the immune system's response to an antigen. Antibodies, act by directly neutralizing the antigen and/or bind to the antigen and signaling marcophages to phagocytose the antigen.
Antibodies in the immune system system of the mother are given to the child in her milk. Also, the act of nursing helps the mother's uterus return to it's normal size.
It is the act of being immune to the disease
The exact molecular details of how interferons act is still unclear. They may make surface-exposed antigens of tumors even more capable of stimulating the immune system, which in turn would elicit a greater response from the T-cells of the immune system
