Study Notes

The lymphatic system consists of lymphatic vessels and lymphoid tissues/organs.
The system transports excess tissue fluid (lymph) back to the circulatory system.
It plays a vital role in body defense and resistance to disease.
The lymphatic system also absorbs digested fat and lipid-soluble vitamins.
Lymphatic vessels are a one-way system that carries lymph towards the heart.
There is no pump, but the milking action of skeletal muscle and rhythmic contraction of smooth muscle help propel lymph.
Lymph begins as tissue fluid derived from blood capillaries and travels through successively larger lymphatic vessels called lymphatic collecting vessels and lymph nodes.
Lymphatic capillaries are much more permeable compared to blood capillaries and have flap-like minivalves that act as one-way doors.
Lymph nodes help protect the body, remove foreign material, and produce lymphocytes that function in the immune response.
Lymphocytes are formed in bone marrow but migrate to lymphatic organs where they proliferate further.
