What is the definition of a specific immune response?
An immune response pertains to any of the body’s response to a foreign substance, such as an antigen. ( Ref. 1) The response intends to protect the body from disease-causing viruses, fungi, bacteria, and parasites. A transplanted organ may also incite an immune response when it is identified as non-self. (
What is specific and non specific immune response?
Nonspecific protective mechanisms repel all microorganisms equally, while the specific immune responses are tailored to particular types of invaders. Both systems work together to thwart organisms from entering and proliferating within the body.
Which is an example of a specific response of the immune system?
For example, the smallpox vaccine contains the antigens specific to smallpox. When a person is vaccinated against smallpox, the immune system responds by stimulating antibody-producing cells that are capable of making smallpox antibodies.
What are the two types of specific immune responses?
There are two broad classes of such responses—antibody responses and cell-mediated immune responses, and they are carried out by different classes of lymphocytes, called B cells and T cells, respectively. In antibody responses, B cells are activated to secrete antibodies, which are proteins called immunoglobulins.
What is primary and secondary immune response?
The action of the immune system can be classified into two parts: the primary and the secondary immune response. The primary immune response displays the first contact of the immune system with an infectious agent whereas all following contacts with the same pathogen are named secondary immune response.
What is immunity short answer?
Immunity refers to the body’s ability to prevent the invasion of pathogens. Pathogens are foreign disease-causing substances, such as bacteria and viruses, and people are exposed to them every day. Antigens are attached to the surface of pathogens and stimulate an immune response in the body.
What is specific defense?
Specific defense (sometimes called adaptive immunity) recognizes and coordinates attacks against specific pathogens. The system can also remember pathogens and produce a powerful response the next time a pathogen enters the body.
What is difference between specific and non-specific feedback?
Specific feedback provides detailed ,or specific information on what the employee did well or poorly. General feedback on the other hand is very non-specific, such as “good job” or “you did great.” General feedback, for the most part, is not very helpful for employees.
What is specific Defence?
What is difference between humoral and cellular immunity?
The humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells. Cellular immunity occurs inside infected cells and is mediated by T lymphocytes. The pathogen’s antigens are expressed on the cell surface or on an antigen-presenting cell.
