Ch. 10 - Lymphatic Flashcards
(39 cards)
Which of the following organs does not have lymphatic vessels?
brain
or placenta
The predominant formed elements of normal lymph fluid are
WBCs
Lymph ducts merge into the venous system at the
subclavian veins
Lymph flows faster in response to
massage
(increases with mounting capillary pressure, greater permeability of the capillary walls, increased metabolic rate, and massage.)
An increased number of lymphocytes in the blood represents a systemic response to _____ infections.
most viral
An organ that is essential to the development of protective immune function in infants but has little or no demonstrated function in adults is the
thymus
The examination of the upper left quadrant of the abdominal cavity is essential to the evaluation of the immune system because of the location of which organ?
spleen
Enlarged tonsils and adenoids may obstruct the
nasopharyngeal passageway.
When enlarged, which lymph nodes are most likely to be a sign of malignancy?
supraclavicular
it may be the sentinel node of Hodgkin lymphoma.
Which lymphatic tissue is normally visible during the physical examination?
Palatine tonsils
located at the back of the mouth on either side of the tongue and can be seen more readily than the adenoids
Lymphoid tissue normally regresses to adult size by
puberty.
A congenital defect in the immune system of a 2-week-old infant may be suspected if
the umbilical cord has not yet dropped off.
delayed separation of the umbilical cord has been associated with abnormal granulocyte function.
During pregnancy, the leukocyte count normally increases because of more
polymorphonuclear leukocytes.
neutrophils, eosinophils, and basophils
As adults age, their ability to resist infection decreases because of lymphatic nodes becoming more
fibrotic.
they become more fibrotic and fatty
Equipment for examining the lymphatic system includes a
centimeter ruler.
Which nodes are most often associated with inflammation?
Tender
Nodes located nearest the palatine tonsils are the
retropharyngeal
Nodes that are palpable just inferior to the chin are the
submental
Nodes located nearest the elbow are the
epitrochlear.
Which landmark is the dividing line between the anterior and posterior cervical triangles?
Sternocleidomastoid
Which nodes are also called Virchow nodes?
Supraclavicular
The harder and more discrete a node, the more likely a(n)
malignancy
tender are more infectious
Normal supraclavicular lymph nodes are
not palpable
When examining lymph nodes near a joint in the arm or leg, which of the following maneuvers is likely to facilitate the examination?
Flexion of the extremity
Bending joint areas will ease taut tissues and allow for better accessibility to palpation
