Study Notes

Lymphatic System Functions

The lymphatic system transports lymph fluid, proteins, and fats.

Lymphatic vs. Blood Vessels

Lymphatic vessels have thinner walls, fewer muscle layers, and less elastic fibers compared to blood vessels.
Lymphatic capillaries have larger pores, allowing for greater permeability.

Lymph Formation

Lymph forms from interstitial fluid that enters lymphatic capillaries.

Lymphatic System Components

The lymphatic system consists of lymph vessels, lymph nodes, lymphoid organs (e.g., spleen, thymus), and lymphoid tissues (e.g., tonsils).
The lymphatic system does not include the pancreas.

Lymphatic System Cells

Lymphocytes and macrophages play a crucial role in the immune response, defending against infections and diseases.

Lymphatic Vessels

Lymphatic vessels are more permeable and have thinner walls than blood vessels.
Lymphatic vessels transport lymph fluid, proteins, and fats.

Interstitial Fluid

Excess fluid and protein in the interstitial fluid compartment are transported back to the bloodstream via the lymphatic system.

Spleen Function

The spleen filters out old or damaged red blood cells from the bloodstream.

Lymphatic Capillaries

Lymphatic capillaries have larger pores, allowing for greater permeability.

Lymph Nodes

Lymph nodes filter lymph fluid, trapping pathogens and activating immune responses.
Lymph nodes are mainly distributed in the neck, armpits, and groin.

Lymphatic Ducts

Lymphatic ducts drain into the subclavian veins, returning lymph to the bloodstream.

Deep Neck Lymph Nodes

Deep neck lymph nodes are located along the internal jugular vein.
