BSC2086 Lymphatic System Questions With Complete
Solutions
abdominal lymph nodes Correct Answers -monitor lymph from
the urinary and reproductive systems
-occur in posterior abdominopelvic wall
alternative pathway Correct Answers -nonspecific, does not
require antibody
-complement C3 breaks down in the blood to C3a and C3b
-C3b binds directly to pathogenic targets
-triggers cascade reaction with autocatalytic effect where C3b
causes more C3 dissociation and thus C3b production
antimicrobial proteins Correct Answers proteins that inhibit
microbial reproduction and provide short-term, nonspecific
resistance to pathogenic bacteria and viruses
axillary lymph nodes Correct Answers -receive lymph from
upper limbs and breast
-concentrated in the armpit
B lymphocytes (B cells) Correct Answers -mature in bone
marrow
-activation causes proliferation and differentiation into plasma
cells that produce antibodies
basophils Correct Answers -secrete chemicals that aid mobility
and action of other leukocytes like leukotrienes, histamine, and
heparin
, blood-thymus barrier Correct Answers formed by reticular
epithelial cells which isolate developing leukocytes from blood-
borne antigens and produce signalling molecules that promote
development and action of T cells
bronchomediastinal trunk Correct Answers drains thoracic
organs and deep thoracic wall
cervical lymph nodes Correct Answers -monitor lymph coming
from head and neck
-deep and superficial group in the neck
chyle Correct Answers lymph containing high lipid content
because of lipids draining from lacteals in small intestines after a
meal
classical pathway Correct Answers -specific immunity
-requires antibody molecule to get started
-antibody binds to antigen on surface of the pathogenic
organism (creates antigen-antibody complex)
-changes antibody's shape
collecting vessels of lymphatic system Correct Answers -often
travel alongside arteries and veins
-pass through many lymph nodes
complement system Correct Answers a group of 30 or more
proteins that contribute to nonspecific resistance and specific
immunity
