Two distinct fluids move through the circulatory system: Blood carries oxygen and nutrients to the body's cells, and carries waste materials away. Blood also carries hormones, which control body processes, and antibodies, to fight invading germs. The heart is the pump that keeps this transport system moving.
The lymphatic circulation as a drainage system illustrated Lymph organs Include the bone marrow, lymph nodes, spleen, and thymus. Precursor cells in the bone marrow produce lymphocytes.
B-lymphocytes B-cells mature in the bone marrow. T-lymphocytes T-cells mature in the thymus gland. They may become enlarged due to a tumor or infection. White blood cells are located within honeycomb structures of the lymph nodes. Lymph nodes are enlarged when the body is infected due to enhanced production of some cells and division of activated T and B cells.
In some cases they may feel enlarged due to past infections; although one may be healthy, one may still feel them residually enlarged.
The lymph is drained from the tissue in microscopic blind-ended vessels called lymph capillaries. These lymph capillaries are very permeable, and because they are not pressurized the lymph fluid can drain easily from the tissue into the lymph capillaries.
The lymphatic system is a network of tissues and organs. It is made up of. Lymph - a fluid that contains white blood cells that defend against germs. Lymph Vessels. The lymphatic system is closely associated with the blood system and represents an accessory route by which lymph fluid can flow from the body’s tissues back into the blood stream. Together, the blood, heart, and blood vessels form the circulatory system. The lymphatic system (lymph, lymph nodes and lymph vessels) supports the circulatory system by draining excess fluids and proteins from tissues back into the bloodstream, thereby preventing tissue swelling.
As with the blood network the lymph vessels form a network throughout the body, unlike the blood the lymph system is a one-way street draining lymph from the tissue and returning it to the blood.
Differences among the various lymphatic tissues significantly affect the form of immunity and relate to how antigens bacteria, virus, fungus, etc.
The major parts of the system are the bone marrow, spleen, thymus gland, lymph nodes, and the tonsils. Other organs, including the heart, lungs, intestines, liver, and skin also contain lymphatic tissue.
These cells may then accumulate in the lymph nodes or other areas of the lymphatic system to form tumors.
There are many benign reasons for enlarged lymph nodes: American Family Physician Normal sized lymph nodes? Human lymph nodes are bean-shaped. They may become enlarged due to a tumor or infection, or lymphoma.
Warwick, Roger; Peter L. Like a burglar alarm they are on guard against intrusive antigen. Like West Point, the nodes are in the business of training a militant elite: Lymph nodes can increase or decrease in size for many reasons, including response to treatment, progression of lymphoma, spontaneous regression of lymphoma, immune activation against lymphoma, infection or the resolving of infection reactive, see aboveand so on.
Therefore, imaging of lymphoma is only an estimate of treatment response and disease direction. Collapsing of necrotic areas in lymph nodes may explain a sudden decrease in a large lymph node. Following treatment "a residual mass persisting on CT after treatment poses a common clinical dilemma:The lymphatic system is a network of tissues and organs.
It is made up of. Lymph - a fluid that contains white blood cells that defend against germs. Alternative Health Services and Lymphatic Therapy Training.
