🟥Lymph nodes are bean-shaped structures that are part of the lymphatic system and play a crucial role in the body's immune system. They filter lymph fluid, trap bacteria and viruses, and contain white blood cells (lymphocytes) that help fight infections. 🟥Lymph nodes are located throughout the body, with concentrations in areas like the neck, armpits, groin, and behind the ears.
Here's a more detailed explanation:
Function:
Filtering:
🟥Lymph nodes filter lymph fluid, which contains bacteria, viruses, and other foreign substances, as it travels through the lymphatic system.
Immune response:
They trap pathogens and activate lymphocytes, which then attack and destroy the foreign substances.
Defense:
Lymph nodes are a critical part of the body's defense system against disease, helping to fight off infections and other illnesses.
Location:
Lymph nodes are found throughout the body, often in clusters near major blood vessels.
Concentrations are found in the neck (cervical nodes), armpits (axillary nodes), groin (inguinal nodes), and behind the ears.
They are also present in the chest (thoracic nodes) and abdomen.
Swollen Lymph Nodes:
Swollen lymph nodes, also called lymphadenopathy, can indicate an infection or other condition.
During an infection, the body produces more lymphocytes, which can cause the lymph nodes to swell.
Swollen lymph nodes may be tender or painful, especially if they are near the site of an infection.
Swollen lymph nodes can also be a sign of cancer, though this is less common than infection.
Causes of Swollen 🟥Lymph Nodes:
Infections:
Common causes include colds, strep throat, and other viral or bacterial infections.
Cancer:
🟥Cancer can spread to 🟥lymph nodes, causing them to swell.
Inflammation:
Autoimmune diseases and other inflammatory conditions can also lead to swollen lymph nodes.
Other:
Medications, injuries, and certain other conditions can also cause lymph nodes to swell.
