T-cells and B-cells are both initially made in the bone marrow. T-cells mature in the thymus. They both freely float around in all lymph nodes and the various lymph organs (e.g., tonsils, spleen...).

Which kind of cells mostly found in lymph?
In the medullary cords = plasma cells & B Cells In the medullary sinus = macrophages B cells and T cells freely float around in all lymph nodes and lymph organs.
What do B cells make in the lymphatic system?
Lymph is formed when the interstitial fluid between gaps in the body's tissues is collected through lymph capillaries and mixed with surrounding substances of the tissues. It is then transported through the lymph vessels and then to lymph nodes and is placed into the blood again via. the right or left subclavian vein, now replenished with immune backup.
A primary function of lymphcytes is?
I think you mean lymphocytes. The B and T cells are lymphocytes that are responsible for destroying unwanted viruses and bacteria in your body. They are cells of the immune system. These cells are found in the lymph nodes.
How are lymphatic nodules different from lymphatic organs?
Lymphatic Nodules-Any of the small bodies located along the lymphatic vessels, particularly at the neck, armpit, and groin, that filter bacteria and foreign particles from lymph fluid. As lymph flows through a lymph node at least 99 % of the antigens in the lymph are removed. The lymphatic organs are organs that produces lymphocytes or is associated with lymphocyte function, for example, the lymph nodes, spleen, and thymus.
A leukocyte formed in lymph tissue which produces antibodies?
The leukocyte you are referring to is a B lymphocyte, also known as B cell. B cells are produced in the bone marrow and mature in lymphatic tissue, such as the spleen and lymph nodes. They have the ability to produce antibodies, which are proteins that help neutralize and eliminate pathogens from the body.
What does the medullary cords of a lymph node contain?
The medullary cords of a lymph node contain: reticular cells, lymphocytes, macrophages and plasma cells. It is important to understand that lymphocytes include both B cells and T cells. Note also that plasma cells derive from B cells. If asked a correct answer could be B cells and also plasma cells depending on the level of the material.
What is the name of the inner region of a lymph node?
The Medulla is the inner region of a lymph node. It contains B cells, plasma cells, and macrophages.
Lymph nodes contain large numbers of white blood cells called?
B Cells and macrophages
What is Difference between tissue fluid and lymph?
when lymph fluid is contained inside lymph vessels or lymph node(lymphatic system) it is called lymph whereas when it is squeezed out of cells b/w the cell membranes it is called tissue fluid
Difference between blood and lymph?
Lymph is mainly leakage from blood vessels, thus it is almost identical EXCEPT for the absence of Red Blood cells.
Explain the immune response in a lymph nodes?
First the structure of a lymph node... we have the cortex, paracortex and the medulla. It is made mainly of recticular cells, then lymphocytes and macrophage. So you have APCs presenting the antigen which enter lymph node via HEV, basically post-capillary venous swelling made of simple cuboidal cells. These allows things in blood to enter the lymph node. Then after that you have the APC interacting with B cells in the cortex and the T helper cells in paracortex. Both B and T cells get stimulated. B cells can either stay in cortex to form secondary follicles / germinal center or migrate to medullary cord to become plasma cells and secrete antibodies. The function of germinal center is to increase antibody affinity, isotope change (change classes) and differentiation and proliferation.
Which kind of cells mostly found in lymph?
In the medullary cords = plasma cells & B Cells In the medullary sinus = macrophages B cells and T cells freely float around in all lymph nodes and lymph organs.
What kind of cells in the lymph nodes produces antibodies?
B-cells
What is mostly likely to happen in a lymph node?
a. attachment of MHC markers to self cells b. production of B and T lymphocytes c. phagocytosis of organisms foreign to the body d. oxygenation of the interstitial fluid e. destruction of red blood cells and recycling of their contents
Can getting punched in the lymph node make it swollen?
Ok literally, just fought my brother, he elbows me 3 times in the jaw and my lymph node is swollen on my left side, hurts lika B as if some1 is stabbing me, was looking for the answer of "what happens when your lymph node gets swollen from being punched" and came across this. Well i have first hand experience with this one so im gonna havta say yes getting punched there swells your lymph node
What is the name of the structural units of lymph node that contain a germinal center?
Is the central ,light staining region within a lymphoid follicle in spleen ,lymph nodes,or mucosal lymphoid tissue that forms during T cell-dependent humoral immune response and is the site of B cell and antibodies affinity maturation and antibodies class swiching .
What are the lymph nodes made out of?
lymph nodes are made out of lymphoid tissuethat is able to receive the lymph and return cleaned lymph back into the circulation. Generally the cell types found in the lymph nodes are antigen-presenting cells (specifically dendritic cells), T cells (both helper CD4 T cells and killer CD8 T cells) and B cells (which produce antibodies).
