lymphatic system
made up of
lymphatic duct
lymph tissue
spleen
thymus
tonsils
L.S
works with the circulatory system
removes waste and excess fluids from the body tissue and works on immunity and fat transportation
Lymph
thin, watery fluid made of intercellular fluid
intercellular fluid
made of water, digested nutrienrs, salts, hormones, oxygen, Co2, lymphocytes, and metabollic wastes
lymphatic vessels
small open ended lymph vessels act like a drain pipe are called lymphatic capillaries
they pick up lymph at the tissues and travel through capillaries to the larger lymphatic vessles
lacteals
small intestines, there are special lymphatic capillaries called lacteals
pick up digested fats
when the lymph is mixed with the fat its called chyle
lymph nodes
glands located all over the body and usually show up in clusters or groups
small, round, oval masses that range from the head of a pinhead in size or to an almond in size
clean and purify lymph then leaves the lymph node by a single lymphatic vessel and moves on to join larger vessels
Right Thoracic Duct
short tube that receives all of the purified lymph from the right side of the head and neck
will empty into the right subclavin vein returning the clean lymph to the blood
Thoracic Duct
much larger, and drains the rest of the body
empties into the left subclavin vein
cisterna chyli
storage area for the purified lymph. Receives chyle from the intestinal lacteals
Tonsils
masses of lymphatic tissue that filter interstitual fluid
palatine tonsils
located on each side of soft palate
adenoids tonsils
located in the nasopharynx
Lingual tonsils
located on the back of the tongue
spleen
organ located beneath the side of the diaphragm and in the back of the upper side of the stomach
produces leukocytes, antibodies. Destroys old RBC and thrombocytes. Filters metabolism and wastes away from all body tissues
Thymus
mass of lymph tissue located in center of the upper chest
wastes away after puberty
after puberty it is replaced with fat and connective tissue
Adenitis
inflammation or infection of the lymph nodes
occues in large quantities
S/S- fever, swollen, painful nodes
treatment- antibiotics, warm moist compresses
Hodgkins disease
chronic disease of lymph nodes
S/S painless swellin of lymph nodes, fever, night sweats, weightloss, fatigue, itching
chemotherapy and radiation
Lymphangitis
inflammation of lymphatic vessels
results from infection in extremity
S/S red streak extending up the arm, fever, chills, tenderness/pain
treatment- antibiotics, rest, elevation of affected part, warm moist compresses
splenomegaly
enlargment of spleen
results from abnormal accumulation of RBC, mono, cirrohsis of liver
S/S swelling, abdominal pain, anemia, leukopenia, thrombocytopenia
treat the underlying cause
Tonsilitis
inflammation of the tonsils
throat pain, dysphagia, fever, yelloe/white spots, swollen lymph nodes
