Lymphatic system
Diseases
Adenitis
-
Occurs in large quantities or harmful substance like a pathogen of cancer cells entering the lymph nodes
S/SX-fever and swollen, painful nodes
-
Treatment includes antibiotics, warm, moist compresses
Hodgkin's Disease
-
S/SX- Painless swelling of lymph nodes, fever, night sweats, weight loss, fatigue and prurius
-
Lymphagitis
-
-
S/SX- red streak extending up the arm or leg source of infection, fever, chills, and tenderness/pain
Treatment- Antibodies, rest, elevation of affected part, and or warm, moist compresses
Splenomegaly
-
Can result from abnormal accumulation of RBC, mono and cirrhosis of the liver
S/SX Swelling and abdominal pain, anemia, leukopenia, thrombocytopenia
Spleen can rupture and can lead to intraperitoneal hemorrhage, shock and death
-
Tonsillitis
-
Throat pain, dysphagia, fever, yellow or white spots on tonsils, swollen lymph nodes
Antibiotics, warm throat irrigations are main treatment
-
Lymph
Is a thin, watery fluid made up of intercellular or interstitial fluid
Mode up of water, digested nutrients, salts, hormones, O2, CO2, lymphocytes ans metabolic wastes like urea
-
Lymph nodes
Or "glands" located all over the body, usually in groups of clusters
Small, round, or oval masses ranging from the size of a pin head to an almond.
Lymph vessels bring lymph to the node, then the node filters the lymph and removes, carbon, cancer cells, pathogens, and dead blood cells
-
The clean/purified lymph then leaves the lymph node by a single lymphatic vessel and moves on to join larger vessels and will eventually drain into one of the lymphatic ducts, right lymphatic duct or thoracic duct
Lymphatic vessels
-
Small, open ended lymph vessels act like a drainpipe are called lymphatic capillaries
Pick up lymph at the tissues then the lymph will travel through the capillaries to the larger lymphatic vessels
-
-
-
Right thoracic duct
Short tube that receives all of the purified lymph from the right side of the head and neck, the rt chest and the rt arm
-
Thoracic duct
Much larger, drains the rest of the body
-
At the start of the thoracic duct, there is a pouch like structure called the cisterna chyli
Cisterna chyli- Is a storage are for the purified lymph it also will receive chyle from the intestinal lacteals
Thymus
-
-
Early in life it produces antibodies, and manufactures lymphocytes to fight infection its function is taken over by the lymph nodes
Spleen
-
It produces leukocytes and antibodies, destroys old erythrocytes, thrombocytes, and filters metabolites and wastes from body tissue
The lymphatic system is made up of lymphatic ducts, lymph tissue, thymus, tonsils, and spleen
-
Removes waste and excess fluids from the body tissue and works on immunity, and lipid transportation
