Study Notes
Functions of the Lymphatic System
- The main function of the lymphatic system is to return leaked fluid and plasma proteins back to the blood.
Importance of Lymphatic System
- Leaked fluid and plasma proteins must return to the blood to maintain blood volume and prevent edema.
Lymphatic Vessels
- The primary purpose of the elaborate network of drainage vessels in the lymphatic system is to return leaked fluids back to the bloodstream.
- Larger lymphatic vessels have minivalves that prevent backflow, similar to veins.
- Minivalves in lymphatic capillaries prevent leaking out of lymph and backflow.
- Collagen filaments in lymphatic capillaries prevent backflow by forming a one-way valve.
Lymphatic System Components
- The thoracic duct drains lymph from the lower extremities, abdomen, and left side of the head and thorax.
- The right lymphatic duct drains lymph from the right upper limb and right side of the head and thorax.
Lymphoid Tissue
- The function of lymphoid tissue is to defend the body against infection and disease.
Lacteals
- Lacteals are specialized lymphatic capillaries in the intestines that absorb dietary fats and transport them to the bloodstream.
Overall Functions
- The major functions of the lymphatic system are to return leaked fluids back to the bloodstream and defend the body against infection and disease.
