This system's funtions are (1) to transport tissue fluid to the blood vessels, and (2) to protect the body by removing foreign material such as bacteria from the lymphatic stream and by serving as a cite for lymphocytes "policing of body fluids and lymphocyte multiplication. It is a one-way system that carries lymph only towards the heart.
Right lymphatic duct
Drains lymph from the right upper extremity, head, and thorax delivered by the jugular, subclavian, and bronchomediastinal trunks. It empties into the venous circulation at the junstion of the internal jugular vein an the subclavian vein.
receives lymph from all other areas of the body with the exception of the right arm, right side of head, and right chest. It empties into the venous circulation at the junction of the internal jugular and subclavian vein.
Bean-shaped filters that cluster along the lymphatic vessels of the body. They function as a cleanser of lymph as wells as a site of T and B cell activation
Found within the lymph nodes, they are phagocytes that destroy bacteria, cancer cells, and other foreign matter in the lymphatic stream.
the prominent sac of the thoracic duct that receives lymph from the digestive viscera
lacated at the back of the nose at place called the nasopharynx; unites the back if mouth with back of the throat
located at the back of the mouth. cells there that can help fight infection and are removed in tonsilectomies. This is the largest and most often infected
The body's largest lymphatic organ which consists of two compartments. One is filled with red pulp (full of RBC that can be released if necessary) and one with white pulp (full of lymphocytes and macrophages)
afferent lymphatic vessels
vessels that travel to the lymph node and are responsible for exposing lymph to the WBCs
found below the capsule in the lymph node. With in this structure is the lymphatic nodule, germinal center
deeper layer under the cortex of the lymph node. It consists of dark staining area which is surrounded by lymph, and plasma cells and acrophages which will respomd if there is something bad that it comes in contact with
Reticular Epithelial Cells
Cells that seal off the cortex of the thymus from the medulla and surround blood vessles and lymphocyte clusters in the cortex. They form a blood-thymus barrier that isolates developing lymphocytes from blood-borne antigens
a member of both the lymphatic and endocrine system because it houses developing lymphocytes and secretes hormones that regulate their later activity
aka lymphoid organs. have well-deingied anatomical sites and at least partial connective tissue capsules that separate the lymphatic tissue from neighboring tissues
a congretation of lymphocytes and macrophages. Often abundant within lymph nodes, tonsils, and appendix
aggrgations of lymphocytes in the connective tissue of mucous membranes and various organs
Natural Killer (NK) cells, T lymphocytes, B Lymphocytes, Macrophages, Dendritic cells, reticular cells
clear, colorless fluid, similar to blood plasma but low in protein. It originates as fluid that has been taken up by th lymphatic vessels. Contains a large number of lymphocytes
the first of the lymphatic vessels which are microscopic and penetrate nearly every tissue of the body. They are closed at one end; it consists of a sac of endothelial cells that loosely overlap each other like shingles and are tethered to surrounding tissue by protein filaments that prevent the sac from collapsing
formed by the convergence of lymphatic capillaries. At irregular intervals, they empty into lymph nodes and they eventually converge to form a larger lymphatic trunk
the convergence of collecting vessels to form a larger vessel which drains a major protion of the body, there are six of these.
