Lymphatic System Flashcards
Functions of the lymphatic system include all except
Filter blood (fluid balance, protection, absorption of fats)
Lymphatic ducts drain into the subclavian veins (t/f)
True
Once fluid enters the lymphatic vessels it is called
Lymph
Movement of lymph toward the hearts includes all except
Lymph nodes contracting (breathing, skeletal muscles contract, smooth muscles contract in lymph vessels)
Which is not a characteristic of lymph vessels
Transport lymph to the tissues (thin walled, blind ended, contract to move lymph forward)
Lymph nodes are isolated throughout the body (t/f)
False
Lymphoid organs include all except
Pancreas (thymus, spleen, tonsils)
Functions of the spleen include all except
Filters lymph (filters blood, reservoir for blood, destroys old red blood cells)
Innate barriers of first line defense include all except
Macrophages (skin, body reflexes, body secretions)
Innate barriers of body reflexes include all except
Antigens (sneezing, coughing, vomiting)
Any foreign substance that enters the body and induced an immune response
Antigen
Compared to plasma, lymph contains much less
Protein
Which vessel returns lymph from the lower extremities to the cardiovascular system
Thoracic duct
Which of the following is not part of barriers, the first line of defense
Complement (tears, saliva, skin)
Which cell destroys certain abnormal cells directly such as cancer cells
Cytotoxic T cells
Type of cells that remember an antigen
Memory T cell
A response of tissue to an injury or infection
Inflammation
An increase in body temperature above normal range
Fever
All defense that protect us constitute
Immunity
A primary function of the lymph nodes
Filter lymph
Lymphatic are not in the following areas except
Legs (bones, brain, spinal cord)
White blood cells taking in and destroying waste, cancer cells, and pathogens
Phagocytosis
B cells produce y-shaped proteins called
Antibodies
The administration of virulent pathogens to stimulate immunity and produce antibodies
Immunization
Part of the first line of defense against ingested or inhaled contaminants
Tonsils
