Anatomy and Physiology
Lymph vessels, ducts, and nodes Protects body from infection Filters bacterial and nonbacterial
products Prevents waste products from entering
circulatory system
2
Anatomy and Physiology
Two divisions of lymph systemLeft lymphatic duct also called thoracic ductRight lymphatic duct drains lymph from head,
upper torso, and right armRest of body drains through left lymphatic duct
4
Common Signs and Symptoms
Enlarged lymph glands or nodes, fever, fatigue, and weight loss
Most diseases of lymphatic system related to diseases of other systems
Lymphocytosis - increased WBCs Lymphcytopenia - decreased WBCs
6
Diagnostic Tests
CBC with differential Lymphangiography - X-ray of lymph
system after dye injection MRI CT Biopsy of lymph nodes
7
Common Diseases of the Lymphatic System
Lymphadenitis - inflammation of lymph glands characterized by swelling, pain, and tenderness
8
Common Diseases of the Lymphatic System
Lymphangiitis - swelling of the lymph vessels due to inflammation caused by strep infections following a traumaCharacterized by red streak at bacterial
entry extending to area of lymph node
9
Common Diseases of the Lymphatic System
LymphangiitisOther symptoms: fever, chills, malaise,
cellulitisTreatment: antibiotics; warm, moist packs;
and elevation of affected area
10
Common Diseases of the Lymphatic System
LymphedemaAbnormal collection of lymph fluid in
extremitiesDiagnosis confirmed by lymphangiographyTreatment includes antibiotics or surgical
intervention depending on cause
11
Common Diseases of the Lymphatic System
LymphomaNeoplasms affecting lymphoid tissueAffects normal lymphocyte production
leading to impaired immunitySymptoms: night sweats, fever, weight lossTreatment may include chemotherapy,
radiation, bone marrow transplantation
12
Common Diseases of the Lymphatic System
MononucleosisViral infectionSomewhat contagious“Kissing disease”
13
Rare Diseases
Kawasaki Disease Symptoms
Rash similar to scarlet feverEdema of feet and handsLethargy, congestion
