What are the two main functions of B cells?

The main functions of B cells are:

• to make antibodies against antigens,
• to perform the role of antigen-presenting cells (APCs),
• to develop into memory B cells after activation by antigen interaction.

Where are B lymphocytes in the body?

B lymphocytes (B cells) are an essential component of the humoral immune response. Produced in the bone marrow, B cells migrate to the spleen and other secondary lymphoid tissues where they mature and differentiate into immunocompetent B cells.

What is the function of B lymphocytes quizlet?

What is the function of B lymphocytes in the immune system? The primary function of B cells is to produce antibody. They participate in the humoral immune response. This means they react to foreign antigens and differentiate into plasma cells once activated.

What is a B lymphocyte?

A type of white blood cell that makes antibodies. B lymphocytes are part of the immune system and develop from stem cells in the bone marrow. A blood stem cell goes through several steps to become a red blood cell, platelet, or white blood cell.

What are B lymphocytes associated with?

B Lymphocytes arise from the bone marrow, gut associated lymphoid tissue. They form the humoral immunity of the body. The viruses and infections which enter the blood or lymph of the body, humoral immunity works against it.

What is the difference between T and B lymphocytes?

Difference Between T Lymphocytes and B Lymphocytes. The key difference between T lymphocytes and B lymphocytes is that the T lymphocytes originate in bone marrows and mature in the thymus while B lymphocytes originate and mature in bone marrows. The main two types of cells in blood are red blood cells ( RBC ) and white blood cells ( WBC ).

Do B lymphocytes make and secrete antibodies?

Antibodies are produced by specialized white blood cells called B lymphocytes (or B cells). When an antigen binds to the B-cell surface, it stimulates the B cell to divide and mature into a group of identical cells called a clone. The mature B cells, called plasma cells, secrete millions of antibodies into the bloodstream and lymphatic system.

What activates B cells?

B cell activation occurs in the secondary lymphoid organs (SLOs), such as the spleen and lymph nodes. After B cells mature in the bone marrow, they migrate through the blood to SLOs, which receive a constant supply of antigen through circulating lymph. At the SLO, B cell activation begins when the B cell binds to an antigen via its BCR .
