LYMPHATIC SYSTEM Flashcards
is a network of
thin tubes that carry a fluid called
lymph throughout your body. It is part
of your immune system, which helps
protect your body from disease.
Lymphatic
System
are small masses
of lymphoid tissue located
in the throat. They are
part of the body’s
lymphatic system and
play a role in the immune
response by helping to
fight off infections that
enter through the mouth
and nose
Tonsils
are two masses of lymphoid tissue located
at the back of the throat, one on each side. They are situated
between the anterior and posterior pillars of the fauces, the
opening between the mouth and the pharynx. The palatine
tonsils play a role in the immune system by helping to fight
off infections that enter through the mouth and throat
Palatine tonsils
, also known as adenoids, are a mass of
lymphoid tissue located at the back of the nasal cavity, in
the upper part of the throat. They play a role in the immune
system by helping to fight off infections entering through
the nose and mouth
Pharyngeal tonsils
are a collection of lymphatic
tissue located at the base of the tongue, on the
back part of the tongue’s dorsum . They are part of
a ring of lymphatic tissue in the pharynx, known as
Waldeyer’s ring.
lingual tonsils
are small, beanshaped structures found
throughout the body as part of
the lymphatic system. They
act as filters for lymph fluid,
which carries white blood cells
and waste products away
from tissues
Lymph nodes
serves as the receptors of the lymph nodes. This
vessel is responsible for receiving unfiltered fluids in slow pace to
remove antigens out more carefully in the lymph node.
afferent vessel
serves as acceptor and exit of the cleaned as well as
filtered fluids which enters the blood stream essential for the formation of
plasma
efferent vessel
are elliptical shaped, surrounded by the cortex and lighter in
color when viewed in the microscope. It has white blood cells which helps
with the filteration process of the fluids to destroy antigens.
Lymph nodules
are located inside the lymph nodules, where they shield
against reinfection by pathogens due to the production of high-affinity
antibodies and B memory cells during an immune response
Germinal centers
is the space between the capsule and the cortex, which allows the transportation of the lymphatic fluid.
LYMPH SINUS
dense connective tissue stroma and collagenous fibers. The capsule sends trabeculae inside the lymph node, which pass inward, radiating towards the center
CAPSULE
in a lymph node plays a vital role in
supplying oxygenated blood and nutrients to
support the immune cells within the lymph
node. The arterial blood supply of lymph nodes
varies depending on their location in the body
artery
in a lymph node is responsible for draining
deoxygenated blood and waste products away from
the lymph node. The hilum of the lymph node is the
primary point of entry for arteries and exit for veins.
