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

Dependent on vascular system Lymph is clear fluid

3

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

Anatomy and Physiology

Organs related to lymph system are tonsils, thymus gland, and spleen

5

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 Mucocutaneous lymph node syndrome

14

Rare Diseases

Rash similar to scarlet feverEdema of feet and handsLethargy, congestion

15

Rare Diseases
