Difference Between Innate Immunity and Acquired Immunity

Innate immunity develops against antigens that are shared by many microbes (called pathogens-associated molecular patterns). Acquired immunity develops against antigens that are specific for each microbe. Host cell receptors are specific, e.g. T cell receptor and B cell immunoglobulin receptor.

What are the similarities and differences between the innate and adaptive immune systems?

Innate immunity is classified into specific and non-specific immunity. Adaptive immunity is classified into Active and Passive immunity. Innate immunity is orchestrated through phagocytes (Macrophages, and Neutrophils) and Natural Killer cells. Adaptive immunity is orchestrated through Lymphocytes.

What are the roles of innate and acquired immunity?

Innate immunity (also called natural or native immunity) provides the early line of defense against microbes. ... Adaptive immunity (also called specific or acquired immunity) system recognizes and reacts to a large number of microbial and nonmicrobial substances.

What is innate immunity and examples?

Innate, or nonspecific, immunity is the defense system with which you were born. ... Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response. Examples of innate immunity include: Cough reflex.

What are the components of innate immunity?

Innate immunity is comprised of different components including physical barriers (tight junctions in the skin, epithelial and mucous membrane surfaces, mucus itself); anatomical barriers; epithelial and phagocytic cell enzymes (i.e., lysozyme), phagocytes (i.e., neutrophils, monocytes, macrophages), inflammation- ...

Is innate or adaptive immunity faster?

The adaptive immune system: Fighting the germs directly

This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster.

What is an example of acquired immunity?

The body responds by making its own antibodies. There are two examples of passive naturally acquired immunity: The placental transfer of IgG from mother to fetus during pregnancy that generally lasts 4 to 6 months after birth; and The IgA and IgG found in human colostrum and milk of babies who are nursed.

What is an example of adaptive immunity?

They can also provide long-lasting protection. A person who recovers from measles, for example, is protected for life against measles by the adaptive immune system, although not against other common viruses, such as those that cause mumps or chickenpox.

How does acquired immunity work?

Immunity is acquired actively when a person is exposed to foreign substances and the immune system responds. Passive immunity is when antibodies are transferred from one host to another. Both actively acquired and passively acquired immunity can be obtained by natural or artificial means.

What are three types of innate immunity?

The innate immune system includes:

• Physical Barriers. such as skin, the gastrointestinal tract, the respiratory tract, the nasopharynx, cilia, eyelashes and other body hair.
• Defense Mechanisms. such as secretions, mucous, bile, gastric acid, saliva, tears, and sweat.
• General Immune Responses.

Are you born with innate immunity?

Innate (natural) immunity is so named because it is present at birth and does not have to be learned through exposure to an invader. It thus provides an immediate response to foreign invaders. However, its components treat all foreign invaders in much the same way.

Is skin innate immunity?

The immune system of the skin has elements of both the innate (nonspecific) and adaptive (specific) immune systems. Immune cells inhabit the epidermis and dermis.
