What components make up the lymphatic system?

The lymphatic system is an essential part of the immune system and fluid balance in the body. It primarily consists of a network of vessels, ducts, nodes, and organs that collectively facilitate the movement of lymph, which is a fluid containing infection-fighting white blood cells.

Lymphatic vessels transport lymph fluid from tissues throughout the body back to the circulatory system. Lymph nodes act as filters, trapping pathogens and facilitating the activation of the immune response. Key organs within the lymphatic system include the spleen, thymus, and tonsils, each playing unique roles in the maturation of lymphocytes and overall immune function.

Together, these components are vital for maintaining fluid balance, absorbing fats from the digestive system, and contributing to the body's defense against infections. This structural organization and functionality highlight the importance of the lymphatic system in health and disease.
