61)
Cisterna chyli.
61)
62)
Lymphatic collecting vessels.
62)
TRUE/FALSE. Write ‘T’ if the statement is true and ‘F’ if the statement is false.
63)
When tissues are inflamed, lymphatic capillaries develop openings that permit uptake of large
particles such as cell debris, pathogens, and cancer cells.
63)
64)
The cisterna chyli collects lymph from the lumbar trunks draining the upper limbs and from the
intestinal trunk draining the digestive organs.
64)
65)
If even a small part of the spleen is left in a ten–year–old child, it will most likely regenerate itself.
65)
66)
Lymphatic capillaries are permeable to proteins.
66)
67)
Peyer’s patches are clusters of lymphoid tissue found primarily in the large intestine.
67)
68)
Lymph capillary permeability is due to minivalves and protein filaments.
68)
69)
Chyle is delivered to the blood via the lymphatic system.
69)
70)
The simplest lymphoid organs are the lymph nodes.
70)
71)
The lymphatic capillaries function to absorb the excess protein–containing interstitial fluid and
return it to the bloodstream.
71)
72)
Lymphoid tissue is mainly reticular connective tissue.
72)
73)
Lymphocytes reside temporarily in lymphoid tissue, then move to other parts of the body.
73)
74)
All the lymphoid organs are well developed before birth.
74)
75)
There are more efferent lymphatic vessels leaving a lymph node than there are afferent vessels
entering a lymph node.
75)
76)
In the spleen, red pulp is involved in the immune functions and white pulp is involved in
disposing of worn–out RBCs.
76)
77)
Like blood, lymph flows both to and from the heart.
77)
78)
Because lymph vessels are very low–pressure conduits, movements of adjacent tissues are
important in propelling lymph through the lymphatics.
78)
79)
The most important role of the spleen is to provide a site for lymphocyte proliferation and immune
surveillance and response.
79)
80)
About 3 liters of fluid are lost to the tissue spaces every 24 hours and are returned to the
bloodstream as lymph.
80)
81)
Digested fats are absorbed from the intestine by the lymph capillaries.
81)

removed. Explain why it might occur.
89)

bleeding. Examination reveals a ruptured spleen. What is the treatment of choice and what is the likely
long–term outcome (prognosis)?
90)
