LYMPHATIC SYSTEM: DISEASES & DISORDERS

Question 1

Abnormal accumulation of lymph in tissues, often the limbs; 70%–90% cases in women; can be caused by
developmental defects, disease, or damage to the lymphatic system

Answer 1

Lymphedema

Question 2

Symptoms occur within a few minutes of exposure to an antigen because antibodies are already present from
prior exposure

Answer 2

Immediate Allergic Reactions

Question 3

Antigen combines with antibodies on mast cells or basophils in the lungs, which then release inflammatory
chemicals that cause constriction of the air tubes, so that the patient has trouble breathing

Answer 3

Asthma

Question 4

Systemic allergic reaction, often resulting from insect stings or drugs such as penicillin; chemicals released from
mast cells and basophils cause systemic vasodilation, increased vascular permeability, drop in blood pressure, and
possibly death

Answer 4

Anaphylaxis

Question 5

Congenital; both B cells and T cells fail to form; unless patient kept in a sterile environment or provided with a
compatible bone marrow transplant, death from infection results

Answer 5

Severe combined immunodeficiency
(SCID)

Question 6

Life-threatening disease caused by the human immunodeficiency virus (HIV)

Answer 6

Acquired immunodeficiency syndrome (AIDS)

Question 7

• Skin lesions, particularly on face
• Fever
• Fatigue
• Arthritis
• Anemia

Answer 7

Systemic Lupus Erythematosus
