Study Notes
Thymus
- Site of T-lymphocyte maturation, crucial for immune system development.
- Involutes with age, becoming less functional after puberty.
- Reaches maximum weight of 30-50 grams around puberty.
Lymph Nodes
- Function primarily to filter lymph and trap foreign particles.
- Do not produce red blood cells; this is not a function of lymph nodes.
Spleen
- Responsible for filtering blood and storing platelets and erythrocytes.
Lymphatic Ducts
- Right lymphatic duct collects lymph from upper body regions, excluding lower limbs.
- Thoracic duct and right lymphatic duct are the two main collecting ducts that drain lymphatic trunks.
Lymph Formation
- Increases due to rising hydrostatic pressure in interstitial fluid, enhancing lymph production.
Lymphatic Capillaries
- Absent in epithelia; play a key role in fluid balance and immune function.
- Unique structure with anchoring filaments that prevent collapse under pressure.
T-Lymphocytes
- Class of white blood cells, named after the thymus gland where they gain immunological maturity.
Tonsils
- Main groups include pharyngeal tonsil, palatine tonsil, and lingual tonsil.
Lymphatic Nodules
- Are not encapsulated; differ from encapsulated lymphatic organs like lymph nodes and spleen.
