Defense refers to the measures and strategies employed to protect against attack, harm, or damage. In various contexts, defense can involve military, legal, environmental, or personal strategies to maintain safety and security.

Military Defense[edit]

In a military context, defense pertains to the actions taken by a state or group to protect its territory and citizens from external threats. This includes the deployment of armed forces, fortification of borders, and implementation of advanced technologies such as radar and missiles. Military defense strategies can be proactive, involving surveillance and intelligence operations, or reactive, as in direct combat situations.

Legal Defense[edit]

In the realm of law, a defense is an argument or strategy used by the defendant to challenge the validity of the plaintiff's claim. This can include denying the facts as presented, claiming mitigating circumstances, or asserting legal excuses such as self-defense or insanity. Legal defenses are critical in both criminal and civil proceedings, influencing the outcomes significantly.

Environmental Defense[edit]

Environmental defense involves actions taken to protect the environment against degradation and pollution. This includes advocacy, legal actions, and implementation of sustainable practices to preserve natural resources and biodiversity. Organizations and governments often enact policies and regulations like the Clean Air Act or the Endangered Species Act to enforce this type of defense.

Personal Defense[edit]

Personal defense refers to measures taken by individuals to protect themselves from physical harm. This can include learning self-defense techniques, using personal security devices, or employing security measures in one's home or digital environments.

Defense Mechanisms[edit]

In psychology, defense mechanisms are unconscious psychological strategies brought into play by various entities to cope with reality and to maintain self-image. Well-known mechanisms include denial, repression, and projection.

-'''Defense''' is a term used in various fields, including [[medicine]], [[psychology]], and [[biology]], to refer to mechanisms or strategies used to protect against harm or damage. In the context of medicine, defense mechanisms are often related to the body's immune system and its ability to fight off disease and infection.

+'''Defense''' refers to the measures and strategies employed to protect against attack, harm, or damage. In various contexts, defense can involve military, legal, environmental, or personal strategies to maintain safety and security.
-The human body has a complex system of [[defense mechanisms]] that work together to protect against disease and infection. These mechanisms can be broadly categorized into two types: innate (non-specific) and adaptive (specific).

This can include denying the facts as presented, claiming mitigating circumstances, or asserting legal excuses such as self-defense or insanity. Legal defenses are critical in both criminal and civil proceedings, influencing the outcomes significantly.
-Innate defense mechanisms are the body's first line of defense against pathogens. They are non-specific, meaning they respond to all pathogens in the same way. These mechanisms include physical barriers like the skin and mucous membranes, as well as cells and chemicals that attack pathogens.
+==Environmental Defense==
+Environmental defense involves actions taken to protect the environment against degradation and pollution. This includes advocacy, legal actions, and implementation of sustainable practices to preserve natural resources and biodiversity. Organizations and governments often enact policies and regulations like the Clean Air Act or the Endangered Species Act to enforce this type of defense.

+==Personal Defense==
+Personal defense refers to measures taken by individuals to protect themselves from physical harm. This can include learning self-defense techniques, using personal security devices, or employing security measures in one's home or digital environments.
-The skin and mucous membranes act as physical barriers, preventing pathogens from entering the body. The skin is the largest organ of the body and provides a tough, physical barrier against pathogens. Mucous membranes, which line the body's internal surfaces, trap pathogens and move them out of the body.
+==Defense Mechanisms==
+In [[psychology]], defense mechanisms are unconscious psychological strategies brought into play by various entities to cope with reality and to maintain self-image. Well-known mechanisms include denial, repression, and projection.

-The body also uses cells and chemicals to attack pathogens. [[White blood cells]], or leukocytes, are a key part of this defense. They can engulf and destroy pathogens in a process called phagocytosis. The body also produces chemicals, like interferons and complement proteins, that inhibit the growth of pathogens and help white blood cells destroy them.

+[[Category:Environmentalism]]
-Adaptive defense mechanisms are the body's second line of defense. They are specific, meaning they target specific pathogens. These mechanisms include [[antibodies]] and [[T cells]], which recognize and destroy specific pathogens.

-==== Antibodies ====
+{{Defense-stub}}
-Antibodies are proteins produced by [[B cells]], a type of white blood cell. They recognize and bind to specific antigens (substances that the body recognizes as foreign), marking them for destruction by other cells of the immune system.
-==== T Cells ====
-T cells are another type of white blood cell. They recognize and kill infected cells directly, and also help coordinate the immune response by signaling other cells to attack.
