Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which cells release free antibodies into the blood and lymph?
A
T cells
B
B cells
C
Helper T cells
D
Macrophages
Explanation: 

Detailed explanation-1: -Plasma cells: Plasma cells release antibodies in response to antigens. Once a B-cell becomes a mature plasma cell, it can release up to 2, 000 antibodies per second. Plasma cells are also called plasmacytes or effector cells.

Detailed explanation-2: -Effector B cells secrete antibodies, which can act over long distances to help eliminate extracellular pathogens and their toxins. Effector T cells, by contrast, act locally at sites of infection to either kill infected host cells or help other cells to eliminate pathogens.

Detailed explanation-3: -A lymphocyte is a type of white blood cell that is part of the immune system. There are two main types of lymphocytes: B cells and T cells. The B cells produce antibodies that are used to attack invading bacteria, viruses, and toxins.

Detailed explanation-4: -The B Cells have the ability to transform into plasmocytes and are responsible for producing antibodies (Abs).

Detailed explanation-5: -B lymphocytes are part of the immune system and develop from stem cells in the bone marrow.

Detailed explanation-6: -Antibodies are produced by B cells (specialized white blood cells). When an antigen comes into contact with a B cell, it causes the B cell to divide and clone. These cloned B cells-or plasma cells-release millions of antibodies into your bloodstream and lymph system.
