Question

Activation of B and T lymphocytes and production of memory lymphocytes are specific cellular responses by which of the following?

a. It consists of non-specific barriers and cellular responses
b. memory cells
c. Filter fluid from intercellular spaces and remove foreign substances and debris
d. The internal aspect of the adaptive immune system

Answer 1

B and T lymphocytes play a crucial role in specific immunity by producing antibodies and attacking foreign or diseased cells. Memory cells provide long-lasting protection.

Step-by-step explanation:

B cells and T cells, also called B lymphocytes and T lymphocytes, play prominent roles in defending the body against specific pathogens (disease-causing microorganisms) and are involved in specific immunity. B cells produce antibodies or immunoglobulins that bind to specific foreign components, while T cells physically attack foreign or diseased cells. Memory cells, which can be both B and T cells, are formed after exposure to a pathogen and mount rapid responses upon subsequent exposures. These memory cells provide long-lasting protection against specific pathogens.
