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.

A malfunction of the lymph nodes would most likely interfere with the?
A malfunction of the lymph nodes would most likely interfere with the body's immune response because lymph nodes are a key part of the immune system, filtering out harmful substances and producing immune cells.
Are there lymph nodes in the jawline?
Yes, there are lymph nodes located along the jawline. These lymph nodes play a role in filtering lymph fluid and immune response in the head and neck region. Swelling or tenderness in these lymph nodes can sometimes be an indication of infection or inflammation in the surrounding areas.
Why does lymph notes swell?
Lymph nodes swell as a normal immune response to infection or inflammation. This swelling occurs as the lymph nodes work to filter and trap viruses, bacteria, or other pathogens. The increased activity of immune cells in the lymph nodes causes them to enlarge.
What causes thickening of a lymph nodes cortex?
Thickening of a lymph nodes cortex is likely caused from things like cancers, and inflammation. With this, comes problems with the immune system and response.
Why does Rubella causes swollen lymph nodes?
Rubella, or German measles, causes swollen lymph nodes as part of the body's immune response to the viral infection. The virus triggers the activation of the immune system, leading to lymphadenopathy, which is the enlargement of lymph nodes. This occurs because lymph nodes are responsible for filtering pathogens and producing immune cells, causing them to swell when fighting off the virus. Swollen lymph nodes are a common symptom in many viral infections, including rubella.
What organ detects pathogens in the lymph?
The organ that detects pathogens in the lymph is the lymph node. Lymph nodes contain immune cells, such as lymphocytes and macrophages, which monitor the lymph fluid for foreign substances, including pathogens. When pathogens are detected, the immune cells initiate an immune response to help eliminate the threat. This process is crucial for the body's immune surveillance and response to infections.
What do lymph nodes assist with?
Lymph nodes play a crucial role in the immune system by filtering lymph fluid, which contains pathogens, toxins, and waste products. They serve as sites where immune cells, such as lymphocytes, can gather and proliferate in response to infections or foreign substances. Additionally, lymph nodes help initiate the body's immune response, promoting the detection and elimination of harmful agents. This process is vital for maintaining overall health and protecting against diseases.
What is the relationship between skin and lymphnodes?
The skin and lymph nodes are both integral components of the immune system. The skin acts as a physical barrier, protecting the body from pathogens, while lymph nodes filter lymph fluid and trap foreign substances, including pathogens and cancer cells, for immune response. Additionally, immune cells within the skin can migrate to lymph nodes to activate and amplify the immune response, illustrating a dynamic interaction between these two systems in maintaining overall health.
Do pigs have a lymph nodes?
Yes, pigs do have lymph nodes. Lymph nodes are an important part of the immune system that helps filter and trap pathogens such as bacteria and viruses.
What is lymph nodes?
lymph node cancer is cancer in your lymph nodes they are all over your body..around you neck stomach legs arms you have lymph nodes all over
Can an umbilical hernia cause swollen lymph nodes?
An umbilical hernia itself typically does not cause swollen lymph nodes. However, if the hernia becomes incarcerated or strangulated, it could lead to infection or inflammation, potentially triggering a response in nearby lymph nodes. In such cases, swollen lymph nodes may occur as part of the body's immune response to the complication. If you experience swollen lymph nodes along with signs of a hernia, it's important to consult a healthcare professional.
Which lymphoid organ serves in immune surveillance and in filtering lymph?
Spleen •Site of lymphocyte proliferation and immune surveillance and response •Cleanses the blood of aged cells and platelets and debris
