LYMPHATIC AND IMMUNE SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
B Cells and T cells both produce memory cells
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Both B and T cells can remember previous encounters with foreign antigens, which helps them to quickly and effectively respond to future infections by the same microorganisms. B cells produce antibodies, which bind to pathogens and mark them for destruction by other immune cells.

Detailed explanation-2: -Three remarkable and unique features of the immune system are specificity, diversity, and memory. Immunological memory involves both T and B cells and results in a secondary antibody response that is faster, of higher affinity, and results in the secretion of non-IgM isotypes of Ig.

Detailed explanation-3: -The T and B lymphocytes (T and B Cells) are involved in the acquired or antigen-specific immune response given that they are the only cells in the organism able to recognize and respond specifically to each antigenic epitope.

Detailed explanation-4: -Memory T cells are antigen-specific T cells that remain long-term after an infection has been eliminated. The memory T cells are quickly converted into large numbers of effector T cells upon reexposure to the specific invading antigen, thus providing a rapid response to past infection.

Detailed explanation-5: -There are two main types lymphocytes: T cells and B cells. B cells produce antibody molecules that can latch on and destroy invading viruses or bacteria. T cells are direct fighters of foreign invaders and also produced cytokines, which are biological substances that help activate other parts of the immune system.
