Lymphatic
Where does lymph originally come from?
Interstitium
Which lymphoid organ is located in the ventral cavity, thoracic cavity, and mediastinum?
Thymus gland
A person has a severe streptococcal pharyngitis (sore throat). He is most likely to develop
painful cervical lymph nodes.
A severe anaphylactic reaction causes death by
respiratory obstruction.
Which T cells destroy pathogens by punching holes in their cell membrane and secreting lymphokines?
Killer
Lymph from the right arm and the right side of the head and thorax drains into the
right lymphatic duct.
The spleen, thymus gland, tonsils, and lymph nodes are classified as what?
lymphoid organs.
Lymph is
formed from tissue fluid.
treatment of choice for an anaphylactic reaction?
Epinephrine and steroid
A breast-fed infant is initially immune to the same diseases as her mom. Which of the following describes the infant’s immunity?
Naturally acquired passive immunity
The spleen does what?
removes worn-out blood cells from circulation.
Elephantiasis is
edema formation in response to impaired lymphatic drainage.
What is least characteristic of the pharyngeal tonsils?
Most commonly removed by tonsillectomy
Cells that represent specific immunity?
B and T cells
The terms pyrexia, febrile, and pyrogenic all refer to
fever.
The right lymphatic duct and the thoracic duct empty into the
subclavian veins.
Lymph is absorbed by lymphatic capillaries from the interstitium. True or False
True
What (are) described as partially encapsulated lymph nodes located in the throat area?
Tonsils
Redness, heat, swelling, and pain are indicative of
inflammation.
A febrile seizure is a seizure that
is caused by a fever.
What is the name of the lymph nodes that drain the head and neck region?
Cervical
What are lymph nodes populated with?
Lymphocytes and macrophages
B and T cells are
lymphocytes.
Phagocytosis requires a specific antigen? True or False
False
An antipyretic drug
lowers a fever.
If proteins are allowed to accumulate in the interstitial space, they will
“hold water” and cause edema.
The lymphatic circulation mimics?
the venous side of the circulation.
What is the effect of a massive release of histamine?
Wheezing and hypotension
IgE, IgA, IgM, and IgG are
antibodies.
describes the function of macrophages?
Phagocytosis and antigen presentation
What condition is most likely to cause a platelet deficiency?
A hyperactive spleen
This organ engages in erythropoiesis in the fetus, produces lymphocytes in the adult, and stores platelets.
Spleen
An allergen is a(n)
antigen.
Which cell engages in cell-to-cell combat?
T cell
Agglutination is the consequence of
antigen–antibody interaction.
What structure is concerned with the processing and maturation of T lymphocytes?
Thymus gland
What is the similarity between the thoracic duct and the right lymphatic duct?
are large lymphatic ducts that collect lymph from smaller lymphatic vessels.
A booster does what?
increases antibodies to an antigen.
What cells are classified as killer, helper, suppressor, and memory?
T cells
This is a group of proteins secreted by virally infected cells; the proteins prevent viral replication.
Interferons
