LYMPHATIC SYSTEM

-Responsible for the removal of interstitial fluid from tissues.

-Absorbs and transports fatty acids from the digestive system.

-Transports white blood cells to and from the lymph nodes into

the bones.

-An important role of the Lymphatic system is to return plasma

proteins into the bloodstream.

-They are a defense mechanism against the body, they filter out

micro organisms and foreign substances.

FUNCTION OF LYMPHATIC SYSTEM

-Lymph nodes; they filter lymph and fight infection

-Thoracic duct; they return cleansed lymph to blood supply

-Thymus gland; generates T cell lymphocytes

-Spleen; lymphatic tissues filter blood and removes cellular debris

-Galt; surrounds intestines, counteracts infection and absorbs fats

-Lymphatic vessels; act as reservoirs for plasma and other substances

-Bone Marrow; generates B cell lymphocytes

ORGANS OF LYMPHATIC SYSTEM

-Located in under arms, groin, and neck

-Children between the ages of 10 to 12 years old usually have larger

lymph nodes.

-The lymph nodes filter and monitor the lymph for foreign particles.

-When you have a cold or any other infection your lymph nodes, may

swell, as lymphocytes fight germs

-Human lymph nodes are bean-shaped

-They range in size from a few millimeters to about 1–2 cm in their

normal state

-Lymph nodes are guards of B, T, and other immune cells

LYMPH NODES

-A two lobed organ located in upper chest

-The thymus gland is a pink-grey organ that lies underneath

the top of the breast bone.

-It’s primary function is to mature lymphocytes

-The T cells travel from the bone marrow to the thymus

gland to mature

-The thymus also produces a hormone called thymosin

-After the age of puberty it gradually becomes smaller.

THYMUS

-Located in the upper far left part of the abdomen, to the

left of the stomach

-It acts as a filter for blood

-The spleen also helps fight certain kinds of bacteria

-It is the largest single mass of lymphoid tissue in the body

-It does however sometimes need to be removed: it can

suffer hidden injury

SPLEEN

Bone marrow plays an important role in this system;

Bone marrow produces lymphocytes that are then transferred to the thymus to mature.

This is why when a person who has an illness where bone marrow is destroyed the persons immune system is very immensely weakened (sudden lack of white blood cells)

BONE MARROW

-In the lymph nodes there are armies of white blood cells

(lymphocytes) that destroy germs

-There are two kinds of lymphocytes; B-cells and T-cells

-B-cells develop into plasma cells that make antibodies to

attack bacteria

-There are two kinds of T cells; Helper and Killer

-Helper T-cells alarm killer T-cells to multiply

-Killer T-cells destroy the cells that the helpers have

identifited

CELLS

-A type of blood cancer

-Happens when lymphocytes begin behaving abnormally

-2 forms Hodgkin and Non Hodgkin

-The main difference between the two is in the specific

lymphocyte each involves.

-Lymphoma typically is present as a solid tumor of lymphoid cells

-This cancer can be curable depending on the type, and stage of

the disease

-30-60% of patients with an aggressive form of Lymphoma can be

cured

LYMPHOMA

-Is an accumulation of lymphatic fluid that causes swelling.

-Mostly in arms and legs

-Develops when lymphatic vessels are missing, impaired, damaged or when lymph nodes have been removed

-Symptoms include; swelling of limbs, feelings of heaviness or tightness in limbs and restricted range of motion.

-Treatment includes; complex decongestive therapy.

-Longer term infection of elephantitis can lead to

Lymphoedema.

LYMPHOEDEMA

-This system consists of organs, ducts, and nodes

The lymphatic system is sometimes called your body’s sewer

-The Lymphatic system is network of “pipes” that drains waste from the

cells

-These ‘pipes’ of the lymphatic system are called lymphatics or lymph

vessels

-The lymphatic system removes excess fluid, and waste products from the

spaces between the cells
