Lymphatic System

Purpose: 1.To drain the extracellular tissues of leaky fluid 2.To provide a place for naive cells to be trained

Lymphatic System Parts: 1.Lymph 2.Lymphatic vessels 3.Nodes 4.Spleen

Lymphatic System Parts: 1.Lymph - Made of water and proteins 2.Lymphatic vessels 3.Nodes 4.Spleen

Lymphatic System Parts: 1.Lymph - Made of water and proteins 2.Lymphatic vessels - Gather lymph and return it to veins (always towards heart) 3.Nodes 4.Spleen

Lymphatic System Parts: 1.Lymph - Made of water and proteins 2.Lymphatic vessels - Gather lymph and return to it to veins (always towards heart) 3.Nodes -Training center for lymphocytes. Also a removal point for pathogens. 4.Spleen

Lymphatic System Parts: 1.Lymph - Made of water and proteins 2.Lymphatic vessels - Gather lymph and return to it to veins (always towards heart) 3.Nodes -Training center for lymphocytes. Also a removal point for pathogens. 4.Spleen - Removal of old and broken RBC’s. Also a place for pathogenic removal by WBC’s and a hangout for B cells

Lymphatic System Disorders: 1.Splenomegaly – swollen spleen due to infection. Ex: Epstein-Barr virus that cause mono.

Lymphatic System Disorders: 2. Tonsillitis – swollen tonsils due to infection. (Tonsils are made of lymphatic tissue)

Lymphatic System Disorders: 3.Lymphedema – blockage of lymph vessels or nodes.

Lymphatic System Disorders: 4. Filariasis (elephantiasis) – Tropical parasitic worms invade the lymph nodes and block them.
