LYMPHATIC SYSTEM
BY XAVIER LOPEZ, DANIEL P
LLEIVA. KYLE FERNANDEZ, ALEX RAMIREZ, ADRIAN CIENFUEGOS.
CERVICAL LYMPH NODES
Posterior lymph nodes are located along the back of the neck.
Deep cervical lymph nodes are associated with their positions
adjacent to the internal jugular vein, which runs near the sides
of the neck. They are known as the lateral jugular, anterior
jugular, and jugulo-digastric lymph nodes.
LYMPHATIC OF THE MAMMARY GLAND
Located beneath the skin and above the pectoral muscle,
the mammary glands produce milk for new born babies. Each gland
consists of a series of lobules, small lobes that produce milk. Tubes
known as ductal lobes carry the milk to the lactiferous ducts, which
open on the nipple. Tiny holes within the nipple secrete the milk.
Fat tissue in the breast surrounds the ducts and glands to protect
them.
CISTERNA CHYLI
The cisterna chyli (or cysterna chyli, and etymologically more
correct, receptaculum chyli) is a dilated sac at the lower end of
the thoracic duct into which lymph from the intestinal trunk and
two lumbar lymphatic trunks flow.
LUMBAR LYMPH NODES
Lumbar lymph nodes refer to a group of small organs that are part
of the immune system. Lymph nodes are generally circular, beanlike organs that are dispersed throughout the body. The lumbar
lymph nodes are located in the region of the body between the
diaphragm (a muscle in the lower rib cage that helps with
breathing), known as the lumbar region. They are also called the
lateral aortic lymph nodes.
PELVIS LYMPH NODES
Pelvic lymph nodes are part of the lymph system, which carries
fluid, nutrients, and waste material between the body tissues
and the bloodstream. Lymph nodes are connected by a system
of channels that run throughout the body. Cancer may spread
through the lymph nodes to distant parts of the body.
LYMPHATICS OF THE LOWER LIMB
The lymphatic system functions to drain tissue fluid, plasma
proteins and other cellular debris back into the blood stream,
and is also involved in immune defense. Once this collection of
substances enters the lymphatic vessels it is known as lymph;
lymph is subsequently filtered by lymph nodes and directed into
the venous system.
THORACIC DUCT
The thoracic duct is the largest lymphatic vessel within the
human body, and plays a key role in the lymphatic system. It is
also called the left lymphatic duct or the alimentary duct.
THYMUS
a lymphoid organ situated in the neck of
vertebrates that produces T cells for the
immune system. The human thymus
becomes much smaller at the approach of
puberty.
AXILLARY LYMPH NODES
The axillary lymph nodes or armpit lymph nodes (20 to 30 in
number) drain lymph vessels from the lateral quadrants of the
breast, the superficial lymph vessels from the walls of the chest
and the abdomen above the level of the navel, and the vessels
from the upper limb.
SPLEEN
An abdominal organ involved in the production and removal of
blood cells in most vertebrates and forming part of the immune
system. This means that this organism removes blood cells in
the immune system
LYMPHATICS OF THE UPPER LIMB
lymph nodes located in and draining the upper limb, ultimately
drained by the subclavian lymphatic trunk; included arethe
axillary, interpectoral, deltopectoral (infraclavicular), brachial,
and cubital nodes.
INGUINAL LYMPH NODES
Any of the superficial lymphatic nodes of the groin made up of
two more or less distinct groups of which one is disposed along
the inguinal ligament and the other about the saphenous
opening—called also inguinal gland.
TONSILLITIS
infection of the tonsils in the throat. infection of the tonsils in
the throat. This causes the patient to not be able to eat nor
breath properly. Tonsillitis usually heals in a few days, but some
people remove there tonsils.
OEDEMA
Edema is a normal response of the body to inflammation or
injury. For example, a twisted ankle, a bee sting, or a skin
infection will all result in edema in the involved area. In some
cases, such as in an infection, this may be beneficial. Increased
fluid from the blood vessels allows more infection-fighting white
blood cell to enter the affected area.
OSTEOARTHRITIS
Osteoarthritis is caused by cartilage
Between the bones wearing down and
when the bones are rubbed together.
GLANDULAR FEVER
Glandular fever can cause fever, sore throat, fatigue, swollen
lymph nodes, and glands. This is caused by Epstein-Barr virus.
This is one of the most common viruses that affect humans.
LYMPHOMA
A cancer of the lymphatic system. -Rare
Fewer than 200,000 US cases per year
Treatable by a medical professional
Requires a medical diagnosis
Lab tests or imaging always required
Symptoms include enlarged lymph nodes, fatigue, and weight
loss.
People may experience:
Whole body: fatigue, loss of appetite, or night sweats
Also common: shortness of breath, swollen lymph nodes, or
weight loss
Treatment may involve chemotherapy, medication, radiation
therapy, and rarely stem-cell transplant.
