Study Notes

Overview of the Lymphatic System

Comprises a network of vessels and nodes to collect and filter excess tissue fluid known as lymph.
Returns lymph to the venous circulation and plays a crucial role in immune defense.

Lymphatic Organs

Spleen:
- Main function is blood filtering, specifically the removal of old red blood cells.
- Contributes to immune response mechanisms.
Thymus:
- Essential for the development and maturation of T lymphocytes, a type of white blood cell crucial for adaptive immunity.
Red Bone Marrow:
- Site for the maturation of immature lymphocytes, akin to thymus function.
Other Organs:
- Contains lymphatic tissue located in the tonsils, appendix, and gastrointestinal tract, contributing to overall immune function.

Lymph Nodes

Kidney-shaped structures, averaging 2.5 cm in diameter.
An adult typically has 400 to 450 lymph nodes, primarily found in the abdomen.
Function to filter foreign particles from lymph and involve immune responses to infections.
Each lymph node houses T lymphocytes, B lymphocytes, and other immune cells, allowing for detection of pathogens in the lymph fluid.
