Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain lymph, relay its formation, composition, circulation and role in immunity from physiology sources, and distinguish lymph from blood, interstitial fluid, plasma and the lymphatic system as the network.

A clear to pale-yellow fluid that circulates in the lymphatic system, formed from interstitial fluid that drains from tissues into lymphatic vessels, carrying white blood cells, especially lymphocytes, fats absorbed from the gut as chyle, proteins and waste, and returning to the bloodstream via lymph nodes and the thoracic duct; the registry alias lymph proper distinguishes the fluid from the wider lymphatic system. Lymph is central to immunity and fluid balance, and blockage or damage to lymph drainage causes lymphoedema, which needs medical management.

What it is for: Fluid balance and immune transport.

It can be explain formation and composition; relay circulation; relay immune role; distinguish related fluids.

Distinguishing features

Clear lymphatic fluid

Carries lymphocytes

Returns fluid to blood

Immune role

What it looks like

A clear to milky-yellow fluid within lymphatic vessels.

Physical character

origin: interstitial fluid note

chyle: fatty lymph from the gut note

registry parents: extracellular fluid, transudate note

How it is recognised

Fluid of the lymphatic system

Lymph proper

Blood carries red cells in vessels; interstitial fluid bathes tissues; plasma is the blood fluid; the lymphatic system is the network of vessels and nodes
