Both the cells are made in the bone marrow.

B cells and T cells are the white blood cells of the system that are liable for adaptive immune reaction in an organism. Both the cells are made in the bone marrow. B cells mature in the bone marrow while the T cells travel to the thymus and mature there. These cells are structurally similar and are involved in adaptive immune reaction in an organism.

These cells mature in the bone marrow and produce antibodies in response to the antigens. B cells are involved in humoral response. As soon as B cells encounter the antigens, they produce plasma cells and memory B cells.

T cells originate within the bone marrow and mature within the thymus. These are often further divided into T helper cells and T cytotoxic cells. They are responsible for removing the pathogens from the body. As soon as the foreign antigen enters the cells, T cells trigger the B cells to develop plasma cells and activate T killer cells that kill the cells affected by the invaders.

Both B cells and T cells share these properties as mentioned –

Q1. What are B cells? Ans – These cells mature in the bone marrow and produce antibodies in response to the antigens. B cells are involved in humoral response. As soon as B cells encounter the antigens, they produce plasma cells and memory B cells. Q2. What are T cells? Ans – T cells originate within the bone marrow and mature within the thymus. These are often further divided into T helper cells and T cytotoxic cells. They are responsible for removing the pathogens from the body. As soon as the foreign antigen enters the cells, T cells trigger the B cells to develop plasma cells and activate T killer cells that kill the cells affected by the invaders. Q3. Mention some of the properties of B and T cells Ans – Some of the properties are –

Q4. Where are B and T cells located? Ans – The B and T cells originate in the bone marrow and mature in the bone marrow and thymus respectively. Q5. How do the T cells activate? Ans – The T helper cells are activated when they are presented with the antigens by the MHC Class II molecules that are expressed on the surface of antigen presenting cells. Q6. Mention the similarities between B cells and T cells Ans – Some of the similarities between B cells and T cells are –
