The Lymphatic System

The lymphatic system includes lymph nodes, which contain macrophages and lymphocytes.
Lymph nodes filter lymph, a fluid containing bacteria, dead cells, and foreign material.
Macrophages destroy foreign material in the lymph nodes.
Lymphocytes, which are white blood cells, multiply in the lymph nodes.
Antibodies produced by lymphocytes are released into the lymph and blood.
Lymph nodes can become inflamed due to infections (lymphadenopathy).

Lymph Nodes

Lymph nodes are located throughout the body, including the face and neck.
Submandibular, deep cervical, and superficial cervical nodes are examples.
Lymph node tissue contains reticular cells, macrophages, and lymphocytes.
The structure of lymph nodes aids filtration of harmful substances.

Spleen

The spleen is the largest lymphatic organ.
It contains reticular and lymphatic tissue.
Located in the left hypochondriac region of the abdomen.
Situated between the stomach fundus and the diaphragm.
Typically measures about 12 cm long, 7 cm wide, and 2.5 cm thick.
Weighs approximately 200 grams.
The spleen's function includes filtering blood and producing lymphocytes.

Explore the components and functions of the lymphatic system, including lymph nodes and the spleen. Understand how lymph nodes filter lymph, the role of macrophages and lymphocytes, and what happens during lymphadenopathy. This quiz covers essential knowledge for a deeper understanding of immunology.
