Organ functions
Small, bean-shaped structures that act as check points that filter lymph fluid and trap harmful substances
Lymph Nodes
A type of cancer that begins in lymphocytes
Lymphoma
network that helps fight infection and balance fluids
Lymphatic system
These are the smallest lymphatic vessels, closed at one end, that collect excess interstitial fluid from tissues into the lymphatic system
Lymphatic Capillaries
Clusters of lymphoid tissue in the throat that trap germs entering through the mouth and nose.
Tonsils
A chronic condition in which fluid buildup in tissues causes swelling, most often in the arms or legs, sometimes due to injury.
Lymphedema
clear fluid carrying white blood cells
Lymph
Lymph flows through progressively larger vessels, including these structures that prevent backflow, similar to veins
Valves
Soft tissue inside bones that produces all blood cells, including immune cells.
Bone marrow
Inflammation and swelling of the tonsils, usually caused by a viral or bacterial infection
Tonsillitis
white blood cells that fight infection
Lymphocytes
This is the main collecting duct of the lymphatic system, draining lymph from the left side of the head, left arm, left thorax, and entire lower body
Organ on the upper left side of the abdomen that filters blood and removes old red blood cells.
Spleen
Enlarged or swollen lymph nodes, often caused by infection, inflammation, or cancer.
Lymphadenopathy
Lymphocytes that mature in the thymus and are responsible for cell-mediated immunity, including killing infected cells and regulating immune responses.
T Cells
Unlike the circulatory system, the lymphatic system lacks a central pump; instead, lymph is moved primarily by these two mechanical forces
Muscle contraction and deep breathing
Gland in the upper chest where T-cells mature and learn to fight infection
Thymus
A rare disorder involving an overgrowth of cells in the lymphatic system.
Castleman disease
Scattered lymphoid tissue found in mucous membranes lining the digestive, respiratory, and reproductive tracts.
MALT (Mucosa-Associated Lymphoid Tissue)
Where does lymph return to the bloodstream through
The subclavian veins
