Question

Which of the following options is true regarding the B-cells?

Options

• They are incapable of leaving lymph tissue to directly confront a foreign antigen.

• Antibodies produced by B-cells travel in lymph and blood to react with the foreign antigens.

• Some may develop into plasma cells that secrete antibodies.

• All of the above

Answer 1

All of the above

Explanation:

• B-cells generally do not leave lymphoid tissues to directly confront antigens; instead, they encounter antigens presented by macrophages or dendritic cells in these tissues.
• Antibodies produced by B-cells (specifically plasma cells, which are differentiated B-cells) travel through lymph and blood to react with antigens throughout the body.
• Some B-cells differentiate into plasma cells that actively secrete antibodies.
