Unit 8 Assignment B:
Understand the impact of disorder on the physiology of the lymphatic system and the associated
corrective treatment
Summary: In this case study, you will learn what the lymphatic system is, how Lymphatic fluid is
formed, what the functions of the lymphatic system are, an example of a patient's case study of
lympedema, the corrective treatment and the side effects of the treatment. You will also learn what this
disease means, how it manifests, how it is treated, how it feels, and what symptoms occur during each
stage.
Introduction: The lymphatic system is composed of specialized tubes and organs that function primarily
to return lymph from the tissue to the bloodstream. Both the circulatory and immunological systems are
comprised of the lymphatic system. The lymphatic system's activities complement those of the
bloodstream by regulating fluid balance in the body and filtering infections from the blood. Lymphatic
capillary meshwork, or lymphatic capillaries, carries fluid from tissues to the lymphatic system. After
leaving the tissues, the lymph travels through the larger lymphatic drainage channels to reach the
bloodstream, where it is deposited. It passes via lymphoid organs, which are packed with immune cells
that check for infections in the incoming lymph.
Lymph
Lymph is a transparent, yellowish fluid found in almost all of the body's tissues. The filtering of plasma
results in the formation of this substance. To transport nutrients, blood plasma diffuses past the
permeable capillary wall into the tissues. Approximately 10% of the fluid stays in the tissue after
reabsorbing into the blood vessels after feeding the cells on the periphery. This is called the interstitial
fluid. The lymph is formed when the interstitial fluid is absorbed into the lymphatic capillaries.
Lymph is mostly made up of water, just like blood plasma. The other components are proteins, lipids,
carbohydrates, ions, and cells. A lymph's composition depends on where it is produced (e.g., lymph
produced in the digestive system is rich in fats). A healthy individual produces two liters of lymph per
day, but this amount varies considerably in pathological circumstances.
Lymphatic capillaries
The tiniest lymphatic veins, lymphatic capillaries collect interstitial fluid from the tissues. They are
structured into lymphatic plexuses, which are networks of lymphatic vessels. Plexuses join together to
form bigger lymphatic veins, which transport lymph from the tissues into the bloodstream.
Lacteal lymphatic capillaries are a unique form of lymphatic capillary. The small intestine's nutrients are
absorbed by these capillaries.
Lymphatic vessels
There are two types of lymphatic vessels: superficial lymphatic vessels and deep lymphatic
vessels. In the subcutaneous layer of the skin, superficial veins collect lymph from the body's
superficial structures. The capillaries drain into deep lymphatic capillaries after following the
, venous system's outflow. Lymph is transported from the interior organs by lymphatic vessels of
the deep lymphatic system. Unlike superficial vessels, deep vessels are accompanied by
arteries. By pressing against the walls of these deep lymphatic vessels, the lymph is able to flow
more freely. Lymph nodes along the way monitor the lymph's content in the superficial and
deep lymphatic tubes. The afferent lymphatic vessels carry lymph to the lymph node, while the
efferent lymphatic vessels carry lymph away from the lymph node. Efferent vessels release their
contents into lymphatic trunks. Each lymphatic trunk is named after the part of the body where
it discharges fluid. There are four pairs of trunks: the lumbar, bronchomedial, subclavian, and
jugular. Lymph drains from the bulk of the gastrointestinal tract's organs through one unpaired
intestinal lymph trunk. A dilated duct opens in the cisterna chyli, which is the thoracic duct's
origin.
The lymphatic trunks subsequently converge into the right lymph duct and the thoracic duct, which are
the two lymphatic ducts.
Lymph is collected from the right upper limb, as well as the right side of the head and chest, by the right
lymphatic duct.
The thoracic duct is a bigger lymphatic channel that gathers lymph from all around the body.
The lymphatic duct transports lymph to the right and left subclavian veins, which drain into the superior
vena cava.
Blood vessels vs. lymphatic vessels
Lymphatic vessels and blood vessels are not the same thing. Starting with the lymphatic system, it is a
one-way street that begins blindly in the tissues and ends in the circulatory system. On the other hand,
capillary networks connect the venous and arterial vessels of the circulatory system, causing blood to
circulate in circles. The lymphatic system doesn't have a pump that regulates the flow of lymph (the
heart) like the circulatory system does. Blood is instead pumped through the lymphatic system as a
result of body motions, artery pulsing, and skeletal muscle contractions. Lymphatic vessels have valves
that prevent it from flowing backwards. There are lymphatic vessels located throughout the body;
however, some tissues and organs do not have lymphatic vessels (e.g., epidermis, cartilage, bone
marrow, and the structures of the eye). The central nervous system was thought to be devoid of
lymphatic vessels for a long time. There are lymphatics in some regions of the central nervous system,
according to new research.
Lymph nodes
The lymph nodes are secondary lymphoid organs throughout the body that are grouped by location
(e.g., axillary, pelvic, mediastinal lymph nodes). There are about 450 lymph nodes in an adult human
being, most of which are in the belly. Lymph nodes contain lymphocytes and other immune cells (e.g.,
macrophages, plasmocytes, dendrocytes). Thanks to the numerous immune cells located within the
lymph nodes, they serve as a filtration point for lymph moving towards the venous system.
