MICROANATOMY

Detailed explanation-1: -Unlike innate immune responses, the adaptive responses are highly specific to the particular pathogen that induced them. They can also provide long-lasting protection.

Detailed explanation-2: -The immune system can be classified into two subsystems: the innate and adaptive immune systems. In general, innate immunity is considered a nonspecific response, whereas the adaptive immune system is thought of as being very specific.

Detailed explanation-3: -The adaptive immune system is made up of: T lymphocytes in the tissue between the body’s cells. B lymphocytes, also found in the tissue between the body’s cells. Antibodies in the blood and other bodily fluids.

Detailed explanation-4: -A type of immunity that develops when a person’s immune system responds to a foreign substance or microorganism, such as after an infection or vaccination.

Detailed explanation-5: -The specificity of the adaptive immune system occurs because it synthesizes millions of different T cell populations, each expressing a TCR that differs in its variable domain. This TCR diversity is achieved by the mutation and recombination of genes that encode these receptors in stem cell precursors of T cells.
