Which is not part of the nonspecific immune defense?
Such nonspecific defenses include the skin and mucosal secretions.
Which of the following is not a part of the non specific immune system?
(D) Killer T-cells – They are a part of acquired immunity. They are involved in the body’s third line of defence. And, hence they are not a part of non-specific defence.

What are the 5 nonspecific immune defenses?
Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN.
Which lasts longer active or passive immunity?
The major advantage to passive immunity is that protection is immediate, whereas active immunity takes time (usually several weeks) to develop. However, passive immunity lasts only for a few weeks or months. Only active immunity is long-lasting.
What’s the non specific immune system?
Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response.
What is an example of specific immunity?
An example is the neutralizing epitope of polioviruses (D antigen) that requires the intact capsid to elicit neutralizing antibodies. The protective protein antigens are highly specific and are unique to each pathogen.
What are three types of immunity?
Humans have three types of immunity — innate, adaptive, and passive:
- Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. …
- Adaptive immunity: Adaptive (or active) immunity develops throughout our lives.
What is tcell?
T cells are part of the immune system and develop from stem cells in the bone marrow. They help protect the body from infection and may help fight cancer. Also called T lymphocyte and thymocyte. Enlarge. Blood cell development.
Are capable of provoking an immune response?
Antigen, substance that is capable of stimulating an immune response, specifically activating lymphocytes, which are the body’s infection-fighting white blood cells. In general, two main divisions of antigens are recognized: foreign antigens (or heteroantigens) and autoantigens (or self-antigens).
Are B cells specific or nonspecific?
B-cells fight bacteria and viruses by making Y-shaped proteins called antibodies, which are specific to each pathogen and are able to lock onto the surface of an invading cell and mark it for destruction by other immune cells.
