Introduction / Function
Answer
The study of lymphatic system
Lymphology
1. Collecting excess ______ from the body's tissues and returning it to the bloodstream in order to balance out fluid levels in the body and
Fluids
2. Help the body absorb ____
Fats
3. Protect against _______ invaders by producing and maturing white blood cells
Foreign
Each day, approximately __ liters of plasma (liquid part of the blood) will flow out of tiny _____ in the thin walls of the capillaries. The plasma will help to deliver oxygen and nutrients to the cell / tissue that surround the capillaries. The surrounding tissue will soak up all the essential substances and then leave behind the waste. The plasma will return the waste into the bloodstream, but, approximately _ liter of plasma each day won't be returned and the remaining plasma will remain around the tissue like someone throwing trash on the street. The remaining plasma will then turn into _____, and this is where the lymphatic system steps in and helps to return the remaining waste.

Lymph
Pathology
Swelling or accumulation of fluid
Lymphedema
Cancer of the lymphatic system
Lymphoma
An inflammation of the lymph vessels
Lymphangitis
A higher-than-normal amount of lymphocytes in the body
Lymphocytosis
A parasitic infection that causes the lymphatic system to malfunction
Lymphatic Filariasis
An overgrowth of cells in the body’s lymphatic system
Castleman disease
An inborn condition, the presence of noncancerous, fluid-like bumps (cysts) under the skin, due to the lymph vessels overgrowing
Lymphangioma
Swollen lymph nodes
Lymphadenopathy
Anatomy
Tubes that form a convoluted network throughout the body that will transport the lymph towards the major ducts. These tubes include veins and capillaries. This is also where the lymph will officially be soaked up from the tissues
Lymphatic Vessels
Situated in the upper chest, this organ / gland is mostly just active prior to puberty. This is where T-lymphocytes will mature and convert from lymphocytes into T-lymphocytes. T-lymphcoytes are essential in fighting foreign invaders
Thymus
Fluid also referred to as lymphatic fluid; this fluid is actually just plasma that didn’t make it back into the capillaries
Lymph
The soft, spongy tissue in the center of certain bones (pelvis, spine, sternum) that accounts for producing approximately 95% of all blood cells.
Bone Marrow
The two main ducts that will receive the lymph from the lymphatic vessels. These ducts will receive the lymph from the vessels, and then return the lymph into the bloodstream by transporting the lymph to the subclavian veins
Collecting Ducts
Bean-shaped glands that monitor and cleanse lymph fluid from damaged cells as it filters through them and also storing leukocytes
Lymph Nodes
The largest lymphatic organ is situated on the left side of the body, beneath the ribs and above the stomach. Most crucial functions - filtration, removal of damaged cells, storing erythro-and thrombocytes in case of emergency
Spleen
This mucus membrane exists throughout the body in places such as in the small intestine, appendix and airways. MALT will monitor and attack and destroy invading germs
Mucosa-Associated Lymphoid Tissue (MALT)
These two structures trap pathogens from everything we consume / inhale and part of the body’s first line of defense against invaders
Tonsils / Adenoids
