The body's ability to defend against disease is called as Immunity. There are two types of Immunity. Innate or by birth and which you aqua-ire. Aqua-re has twocomponents1) Humeral 2) cell mediated.
Exposure to a disease-causing organism typically results in acquired immunity, either through natural infection or vaccination. This type of immunity is specific to that particular organism and provides protection against future encounters with the same pathogen.
Langerhans cells are epidermal cells that play a key role in immunity and disease resistance. They act as antigen-presenting cells, initiating immune responses in the skin by capturing and processing antigens to activate T cells.
A susceptible organism is an organism that is vulnerable to infection or harm from certain pathogens or toxins. These organisms lack immunity or resistance to specific threats, making them more likely to become ill when exposed. Enhancing immunity through vaccinations, proper hygiene, and healthy living can help reduce susceptibility to diseases.
Physical barriers like skin and mucus membrane protects body from invasion of microorganisms. If they happen to cross these barriers, then 'innate immunity' of body kills the bacteria. If they happen to be pathogenic bacteria, then white blood cells go there and engulf them. They are helped by 'humeral' immunity of body. Thensubsequently immunity comes into action by 2 weeks to defend further attack by the same organism.
Immunity is generally a resistance to ailments and infections. Some people are bless with naturally good immune systems, while others are not so lucky and suffer from allergies as well as from ailments. The immune system can be fired up by taking small quantities of the threatening disease so that the body gets used to fighting it; that's the principle behind 'flu shots etc.
The medical term for disease resistance is immunity.
Immunity.Depending on how an organism becomes immune to an INFECTIOUS disease, classifies the immunity into :Active/ PassiveNatural/ ArtificialActive immunity- the organism produced its own antibodies to the disease.Passive immunity- the organism was given antibodies to fight the disease (this type does not last.. so that if the organism is re-infected with the SAME disease...it is not resistant like previously)Natural immunity- the organism naturally was infected to develop active immunity or given antibodies (from mother's milk).Artificial- the organism was deliberately infected to develop active immunity or given extracted antibodies (probably produced from rat's spleen).
Resistance to disease or poison refers to an organism's ability to withstand the harmful effects of pathogens or toxins. This resistance can be influenced by various factors, including genetics, immunity, and detoxification mechanisms. Strong resistance can help prevent illness or death in the face of exposure to harmful agents.
(Immunity : medical is resistance to disease, legal is unable to be prosecuted) "When you get a disease and you recover from it, you usually gain immunity to that disease." "For revealing the mob's secrets, the informer was given immunity."
Natural Active Immunity
Exposure to a disease-causing organism typically results in acquired immunity, either through natural infection or vaccination. This type of immunity is specific to that particular organism and provides protection against future encounters with the same pathogen.

Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. For example, measles antibody will protect a person who is exposed to measles disease, but will have no effect if he or she is exposed to mumps. There are two types of immunity: active and passive. Active Immunity Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Exposure to the disease organism can occur through infection with the actual disease (resulting in natural immunity), or introduction of a killed or weakened form of the disease organism through vaccination (vaccine-induced immunity). Either way, if an immune person comes into contact with that disease in the future, their immune system will recognize it and immediately produce the antibodies needed to fight it. Active immunity is long-lasting, and sometimes life-long.
Naturally acquired active immunity is the type of resistance that is acquired from developing a disease. Naturally acquired active immunity leaves the person immune from developing the disease again in the future.
It depends on what you mean. If it is to a specific disease, it can be a number of things. If you mean a general lack of resistance, it is an immune defficiency. HIV and AIDS are examples of these.
