Difference Between B Lymphocytes and T Lymphocytes
Main Difference
Lymphocytes are white blood cells that fight infection and antibodies and strengthen the immune system. Lymphocytes are divided into two parts, B lymphocytes and T lymphocytes, also known as B cells and T cells. B lymphocytes originate from the bone marrow and lymph nodes, while T lymphocytes originate from the thymus. The function of these two lymphocytes is to protect the body against infection and they are necessary components of our immune system. Without B and T lymphocytes our body will lose the ability to fight and stop different infections and viruses that enter our body. These lymphocytes are also known as B cells and T cells. In simpler words, the function of these two lymphocytes is that after T and B lymphocytes develop, they go to their respective site and when they find an infection from the outside they go into action, the helper T cells send signals to the B cells that produce the plasma cells, these plasma cells act instantly and produce the specialized antibody for that particular infection and coat or covers the cell that is infected in the specific organ. After that, the B cells signal back to the T cells that produce killer cells and kill or destroy the infection. Both cannot function without the other. They work together to strengthen the immune system. These plasma cells act instantly and produce the specialized antibody for that particular infection and coat or coat the cell that is infected in the specific organ. Thereafter, the B cells send signals back to the T cells which produce killer cells and kill or destroy the infection. Both cannot function without the other. They work together to strengthen the immune system. these plasma cells act instantly and produce the specialized antibody for that particular infection and coat or coat the cell that is infected in the specific organ.

Definition of B lymphocytes
B lymphocytes arise from the bone marrow, gut-associated lymphoid tissue. They form the humoral immunity of the body. Viruses and infections that enter the blood or lymph of the body, humoral immunity acts against them. B lymphocytes initially produce proteins called antibodies that can capture infections as they travel through the blood. When they encounter infections, B lymphocytes are stimulated into action and produce plasma cells and memory B cells. Each plasma cell is specialized to produce a particular antibody, a specialized protein to attack a specific infection. The function of the antibodies is to act as a cover over the infected cell so that the T lymphocytes recognize which cells to destroy. When infections are covered with antibodies, They are more easily attacked by other immune system proteins, as well as by specialized cells known as phagocytes that are responsible for ingesting foreign substances and infected cells. While plasma cells disappear after an immune response ends, memory B cells remain for a long time. If the same infection comes back, antibodies are already available to help fight it.
Definition of T lymphocytes
T lymphocytes are an important component of our immune system. They develop in the thymus and then travel through the blood or lymphatic system or to different organs in the body. As soon as they are triggered by a specific infection, helper T cells produce chemicals, of which some chemicals stimulate B cells to become plasma cells, while others stimulate killer T cells to target cells. and kill cells that may have become infected by the infection or become cancerous. Regulatory T cells help control the immune system to keep it from getting out of control. Natural killer T cells also produce chemicals to help regulate the immune response and protect against infections and cancerous tumors. Memory T cells remain for a long time after the immune system has stopped responding. In this way,
- B lymphocytes originate from the bone marrow while T lymphocytes originate from the thymus.
- B cells are found outside the lymph node, while T cells are found inside the lymph nodes.
- B cells can connect to antibodies directly on the surface of the attacking virus or infection, while T cells can only connect to antibodies to the virus on the outside of infected cells.
- B lymphocytes have a short lifespan while the lifespan of T lymphocytes is longer.
- B lymphocytes have surface antibodies present on them and secrete antibodies while T lymphocytes do not have surface antibodies and secrete lymphokines.
- B lymphocytes make up 20% of lymphocytes and form plasma and memory cells, while T cells make up 80% of lymphocytes and form helper, suppressor, and killer cells.
- B lymphocytes do not move to the site of infection while T lymphocytes move to the site of infection.
- B lymphocytes protect against infections and bacteria that enter the blood and lymph, while T lymphocytes fight pathogens that enter the cells.
Final Thoughts
This article has explained the main terms and issues related to these two terms and thus provides a detailed analysis of the differences between them. It also helps make sure that people can learn more about the topics and end up knowing how they are different from each other even though they may seem similar.
