Question
What cells provide humoral specific immunity by secreting antibodies into the blood and lymph?
A. B cells
B. NK cells
C. T cells
D. Monocyte cells
Solution
Answering the Question
The cells that provide humoral specific immunity by secreting antibodies into the blood and lymph are:
A. B cells
Explanation
B cells, also known as B lymphocytes, are a crucial component of the adaptive immune system. When activated by the presence of antigens, B cells differentiate into plasma cells, which produce and secrete antibodies. These antibodies bind specifically to antigens, allowing for the neutralization and marking of pathogens for destruction. This process is essential for the body's ability to remember and respond faster to previously encountered infections, a function known as immunological memory. Other cell types listed, like NK cells (natural killer cells), T cells, and monocytes, have different roles in the immune response that do not involve the production of antibodies.
