Lymphatic system houses
immune cells
Body’s ability to detect and combat pathogens
immunity
The lymphatic system aids the cardiovascular system by
returning excess fluid to venous blood

lymph
lymph is derived from
interstitial fluid that is not reabsorbed into the bloodstream during capillary exchange
blind-ended tubes with openings that allow entry of lymph fluid, situated near capillary beds

Lymphatic capillaries in the GI tract specialized to absorb lipid-soluble substances
Lacteals

lymphatic vessels
Lymphatic vessels lead into two main
lymphatic ducts
What are the 2 main lymphatic ducts
- Right lymphatic duct 2. Thoracic duct
Receives lymph from upper right side of body
Right lymphatic duct
Receives lymph from the rest of the body
thoracic duct
The lymphatic ducts drain into the
subclavian veins
subclavian veins return fluid to
the cardiovascular system
Accumulation due to interference with lymphatic drainage
lymphedema
Involved with formation and maturation of lymphocytes
Primary lymphatic structures
Primary lymphatic structures include what 2 things
- Red bone marrow 2. Thymus glad
Not involved with lymphocyte formation
Secondary lymphatic structures
What 5 things are part of the secondary lymphatic structures
- Lymph nodes 2. spleen 3. tonsils 4. lymphatic nodules 5. MALT
Lymphocytes are derived from
hemocytoblasts
What are the 3 types of lymphocytes
- T lymphocytes 2. B lymphocytes 3. Natural killer cells
Responsible for cell-mediated immunity
