Study Notes
Lymphatic System and Lymphoid Organs Overview
- Lymphatic vessels form a one-way system directing lymph flow towards the heart
- Lymph vessels include microscopic, permeable capillaries, collecting vessels, and trunks
- Lymphatic capillaries are highly permeable and have one-way valves to allow fluid entry but prevent escape
- During inflammation, lymph capillaries absorb cell debris, pathogens, and cancer cells
- Lacteals are specialized lymph capillaries in the intestinal mucosa that absorb digested fat
- Lymphatic collecting vessels have thinner walls, internal valves, and frequently anastomose
- Lymphatic trunks are formed by the union of collecting vessels and drain large body areas
- Two main lymphatic trunks are the right lymphatic duct and the thoracic duct
- The lymphatic system lacks a pump and uses methods like skeletal muscle contraction for lymph transportation
- Lymphoid organs include lymph nodes, spleen, thymus, tonsils, and Peyer’s patches
- Lymphocytes, including T cells and B cells, are the main cells involved in the immune response
- Lymph nodes are principal organs for filtration, immune system activation, and house lymphocytes to proliferate
