Salvo: Massage Therapy
MULTIPLE CHOICE
1. Which functions does the lymphatic system perform?
a. Digestion, absorption, and elimination of ingested substances
b. Production of heat, maintenance of posture, and production of movement
c. Regulation of reproductive processes and helping the body adapt during stress
d. Protection of the body through defense mechanisms and transportation of fats
ANS: D
The lymphatic system removes excess interstitial fluid, transports fats and fat-soluble
vitamins, and protects the body through defense mechanisms.
2. From which fluid is lymph derived?
a. Plasma
b. Interstitial fluid
c. Synovial fluid
d. Cytosol
ANS: B
Lymph, or lymphatic fluid, is the nearly colorless watery fluid circulating through lymphatic
vessels. Lymph is derived from interstitial fluid that is collected by lymphatic capillaries.
3. What do lymph capillaries merge to form?
a. Lymph ducts
b. Lymph nodes
c. Lymphatic vessels
d. Lymphatic ducts
ANS: C
Lymph capillaries merge to form lymphatic vessels. These vessels contain more valves
compared with veins and, like venous valves, open in only one direction, permitting lymph to
flow toward the center of the body.
4. Which regions does the right lymphatic duct drain lymph from?
a. Right lower extremity and foot
b. Right arm, left arm, and entire trunk
c. Right abdomen, left side of the head, and right arm
d. Right arm, right side of the head, and right half of the thorax
ANS: D
The right lymphatic duct drains the right side of the head and neck, the right upper extremity,
and the right half of the upper trunk, and delivers the lymph to the right subclavian vein.
5. Where does the thoracic duct deliver lymph?
a. Left jugular vein
b. Abdominal aorta
c. Left subclavian vein
, d. Right subclavian vein
ANS: C
The thoracic duct drains the rest of the body and delivers the lymph to the left subclavian
vein. The thoracic duct begins at the cisterna chyli, a lymphatic sac located between the
abdominal aorta and L2, and lies anterior to the vertebral column.
6. What is the name of lymphatic sac located between the abdominal aorta and L2?
a. Tonsil
b. Appendix
c. Peyer patch
d. Cisterna chyli
ANS: D
The cisterna chyli is a lymphatic sac located between the abdominal aorta and L2, and anterior
to the vertebral column.
7. Which term is used to describe the movement of lymph through the body?
a. Active transport
b. Peristalsis
c. Lymphokinesis
d. Lymph drainage
ANS: C
Lymphokinesis is the movement of lymph through the body.
8. Which factor promotes the flow of lymphatic fluid?
a. Skeletal muscle movem e n ts
T E S TBANKSELLER.COM
b. Digestive movements
c. Lack of valves in the vessels
d. Release from compression by bandages
ANS: A
Lymph moves by the milking action of the skeletal muscles, pressure differentials in the
thoracic and abdominal cavities created by the movement of the diaphragm and chest during
respiration, the contraction and relaxation of smooth muscles within the walls of the vessels,
and presence of valves to prevent backflow. Lymph can also move by compressive forces
such as massage, clothing, bandages, and even hydrostatic pressure from water.
9. Which structures are the primary lymphatic organs?
a. Skin and receptors
b. Brain and spinal cord
c. Heart and blood vessels
d. Red bone marrow and thymus
ANS: D
Primary lymphatic organs are involved with the production and maturation of lymphocytes.
Primary lymphatic organs include red bone marrow located in spongy bone and the thymus
located behind the sternum.
10. What percentage of the total white blood count is represented by lymphocytes?
a. 10%
