Final answer:
Lymphedema is the term to describe the stopping or obstruction of normal lymph flow, resulting in the buildup of lymph fluid in the tissues, which can lead to swelling and compromised immune function.
Step-by-step explanation:
The stopping or obstruction of normal lymph flow is called lymphedema. The lymphatic system's main function is to transport and filter lymph—the fluid containing white blood cells that helps to fight infection. When this system is obstructed, fluid can start to build up, leading to swelling and other complications.
Lymphedema can be caused by anything that restricts normal lymph flow, such as chronic inflammation, infections like lymphangitis, or physical obstructions within the lymphatic system. The consequences of impeded lymph flow include swelling, decreased immune function, and pain. For example, during the process of clonal expansion, any disruption in lymph circulation can affect the immune response as it hampers the distribution and activation of B cells.
Conditions such as chyluria reveal the importance of the lymphatic system in processes such as transportation of chylomicrons. When the lymphatic system is compromised, it can manifest in various clinical symptoms and may require medical intervention to manage the effects and restore normal function.
