Study Notes

Lymphatic System Overview

The right lymphatic duct does not receive lymph from the lower limb.
The thymus involutes and becomes nonfunctional with aging.
Lymph nodes do not produce red blood cells; their main functions include filtering lymph and housing immune cells.

Tonsils and Lymphatic Nodules

Pharyngeal tonsils are also known as adenoids.
Lymphatic nodules are not encapsulated lymphatic organs.

Lymphatic Pathway and Function

Lymphatic vessels reabsorb interstitial fluid, returning it to the venous circulation.
The two collecting ducts are the thoracic duct and right lymphatic duct.
Hydrostatic pressure in tissue fluid increases lymph formation, aiding in fluid balance.
Primary functions of lymph include returning proteins to the bloodstream and transporting foreign particles to lymph nodes.

The hilum is the region of a lymph node through which blood vessels and nerves pass.
Axillary lymph nodes primarily receive lymph from the upper limb and mammary gland.
Lymphatic capillaries are absent in epithelial tissues but found throughout other body regions.

Cellular Components and Their Actions

Macrophages in lymph nodes engulf and destroy damaged cells and foreign substances.
T-lymphocytes mature in the thymus and are named accordingly.

Spleen Functions and Structure

The spleen consists of red and white pulp and serves as a reservoir for platelets and erythrocytes.
The spleen filters blood, phagocytoses old erythrocytes, and maintains a significant store of platelets.
Other than red bone marrow, the spleen contains the largest single store of platelets.

Peyer Patches and MALT

Peyer patches are large accumulations of MALT located in the small intestine.

Lymphatic Capillary Functionality

Lymphatic capillaries rely on anchoring filaments to prevent collapse under high interstitial fluid pressure.

Sequential Pathway of Lymph

The flow of lymph follows this pathway:
- Lymphatic capillary
- Afferent lymphatic vessel
- Lymph node
- Efferent lymphatic vessel
- Lymphatic trunk
- Collecting duct
- Subclavian vein

Growth and Maturation

The thymus grows until puberty, reaching a maximum weight of 30 to 50 grams.
