The most important functions of the lymphatic system is/are
fluid balance of the internal environment
immunity
fluid balance of the internal environment and immunity
none of the above
Lymph from the entire body drains into the thoracic duct, except lymph from the
upper right quadrant
upper left quadrant
lower limbs
entire head and neck
Which of the following is not a difference between lymphatic and veins?
Lymphatics have thinner walls
Lymphatics contain more valves
Lymphatics contain lymph nodes
Lymphatics endure greater pressure
Lymphatic circulation begins with lymphatic
capillaries
veins
venules
arterioles
The lymphatic system could be referred to as a specialized component of the circulatory system.
Lymphatic vessels, like vessels in the blood vascular system, form a closed loop of circulation.
Both lymph and interstitial fluid closely resemble blood plasma in composition.
Lymphatics have one-way valves much like veins.
The milky lymph found in lacteals after digestion is called chyle.
A dilated structure on the throracic duct that serves as a storage area for lymph moving toward its point of entry into the venous system is the cisterna chyli.
Activities that result in central movement or flow, of lymph are called lymphokinetic actions.
The small depression of the lymph node from which the efferent lymph vessel arises is termed the
sinus
hilium
capsule
nodule
The lymph nodes located in front of the ear are called the
submaxillary groups
inguinal lymph nodes
cervical lymph nodes
The lymphatic tissue of lymph nodes serves as the final maturation site for
monocytes
lymphocytes
monocytes and lymphocytes
Even though some lymph nodes occur as clusters, most occur as single nodes.
Cortical nodules are composed of packed lymphocytes that surround an area called the germinal center.
Over 85% of the lymph from the breast enters lymph nodes of the
axillary region
supraclavicular region
brachial region
subscapular region
The breast - mammary gland and surrounding tissue - is drained by
a. lymphatics that originate in and drain the skin over the breast, with the exception of the areola and nipple
b. lympatics that originate in and drain the substance of the breast itself including the skin of the areola and nipple
c. both a and b
d. none of the above
The thymus secretes
T3
T4
thymosin
both T3 and T4
The thymus is located
deep to the thyroid
in the axillary region
in the mediastinum
As a person ages, the thymus increases in size; this process is called involution
The spleen functions solely in defense from foreign microorganism.
The spleen removes imperfect platelets from the blood.
Palatine, pharyngeal, tubal, and lingual are examples
thymus
tonsils
spleen
Hematopoiesis
Located in the mediastinum
Serves as reservoir for blood
T lymphocites
Largest at puberty
The cisterna chyli is a dilated structure on the thoracic duct that serves as a storage area for lymph moving into the venous system
Healthy capillaries leak proteins
Thoracic duct lymph is pumped into the venous system during inspiration.
Lymph nodes have several afferent and efferent vessels
An anastomosis is the removal of a part
The spleen is located below the diaphragm above the right kidney and descending colon
