This lymphatic system diagram shows the general structure of the system.
The three parts of the lymphatic system are:
The functions of the system are:
In the diagram below, we can see that lymph vessels begin as small closed end tubes found in the spaces between cells within tissue.
After the tissue fluid enters the lymph capillaries (the smallest vessels) it is referred to as lymph.
Lymph capillaries merge to form larger lymph ducts.
Lymph vessels (ducts) that transport lymph to a lymph node are called afferent lymph vessels, and vessels that carry it away from a lymph node is called the efferent lymph vessel.
Along lymph vessels we find lymph nodes.
The word "node" in anatomy means "a knot-like mass of tissue."
A lymph node is a small ball-shaped organ of the immune system, distributed widely throughout the body.
Lymph nodes filter the blood and contain specialized white blood cells which fight infection.
Lymph node location: Humans have approximately 500-600 lymph nodes distributed throughout the body, with clusters found in the underarms, groin, neck, chest, and abdomen. Lymph nodes are linked by lymphatic vessels.
This circulatory system diagram shows and defines its two main parts - in plain English.
