Initial Post Instructions

Choose one of the following topics for your initial post:

A. How do the various components of the lymphatic system operate? We have discussed many organ systems. In what ways are components of the lymphatic system involved in other organ systems? Focus on one element of this system and provide an in-depth view of its contribution to our overall health.

B. How do the various elements of the nonspecific immune system function in providing daily protection against a variety of pathogens? Each student should provide a unique aspect of the nonspecific immune system and educate others on its function and effectiveness (or ineffectiveness) against one class of pathogens.

Primary lymphatic vessels transport lymph from the interstitial space to the regional lymph nodes. Secondary lymphatic vessels then carry the lymph to the main veins. Lymph nodes store lymphocytes, which are released into the circulation during infection. The thymus is the site for T lymphocyte maturation. The immune function of the lymphatic system contributes to overall health. Transporting lipids from the intestines to the liver also partially relies on lymphatic vessels. The spleen filters blood, stores some blood cells, destroys aged cells, and participates in hematopoiesis early in life. “The ubiquitous system of distribution of lymphatic vessels ensures that harmful substances are collected, filtered, neutralized, and excreted” (Sneddon & Elwell, 2020).
