Transcript of Copy of The Lymphatic System

The Lymphatic System
Major Functions
Transports fluids lost by seepage back to the blood stream
Structures
Pathology/ Disorders
Leukemia
Allergy
Anemia
Thrombosis
Hemophilia
Hemorrhage
Hyperglycemia
Lymphoma
Bibliography
Overview
system of capillaries, vessels, nodes and other organs
transport lymph from tissues and returns it to the bloodstream.
transports fatty acids from the intestines to the circulatory system
most tissue of these organs cleans the lymph
Protects the body
Helps fats absorb into the bloodstream
Transporting fluids
Transports proteins and fluids (lymph), lost by
capillary seepage
, back to the blood stream
Lymphatic capillaries
and
vessels
move
lymph
with pressure
Pressure is formed in the limbs by muscles contracting
Pressure is formed in the abdomen by breathing
Check valves
stop lymph from moving backwards
Protecting the Body
prevents fluid build up in the tissues of the body, which can lead to death
Acts as a filter, removes
pathogens
and
antigens
from the blood
white blood cells
found in lymph fight antigens
Helping Fats
transports
fatty acids
from the digestive system
lacteals
absorb the fatty acids and transport them with
lymph

the fatty acids turn lymph into
chyle
chyle is taken through the
lymphatic vessels
to
thoracic ducts
to enter the liver's bloodstream to be metabolized
Major Structures
thoracic duct
lymph nodes
lymphatic vessels
How does this System Work With Other Systems
Works closely with the Immune System
Both the Immune and Lymphatic Systems contain elements to fight off pathogens and antigens to protect the body
Lymphocytes
milky white fluid
white blood cells and chyle
found in vessels, capillaries, in between cells
cleans out fats under skin
Lymph Capillaries
very small vessels
have thin walls
sealed shut on one end
drains extra fluids
found all over the body
small, kidney-shaped organs
there are several hundred lymph nodes found mostly throughout the thorax and abdomen
outside is made from dense fibrous connective tissue
is filled with reticular tissue
Reticular tissue: made out of lymphocytes and macrophages
act as filters and kill microbes
Lymphatic Vessels
tubular structures
responsible for carrying lymph
transports fluid to and from the lymph nodes
has shutoff valves
Lymphatic Nodules
small, localized collection of lymphoid tissue
contain germinal centres
collections of lymph nodules are called Peyer’s patches
tonsils are also local regions where the nodules have merged
Lymph Nodes
Lymphatic Ducts
Thoracic Duct: contains legs, abdomen, left arm, and the left side of the head, neck, and thorax
Right Lymphatic Ducts connects the lymphatic vessels of the right arm and the right side of the head, neck, and thorax to the right brachiocephalic vein.
Return lymph back to the venous blood supply so that it can be circulated as plasma
lymphocytes
lymph capillaries
lymph
lymphatic vessels
lymphatic nodules
lymphatic ducts
lymph nodes
Its a form of small white blood cell
There are T cells, and B cells
T cells are made in the Thymus
B cells are made in the bone marrow
fight off pathogens
Lymph

Leukemia
Any of a group of diseases of the blood involving the uncontrolled increase of white blood cells
ALL
CLL
Allergy
referred to as allergic rhinitis
typically occur in the nose and eyes
coughing, headache, sneezing
itching nose, mouth or eyes
Anemia
reduction of red blood cells and or their volume
symptoms: hypoxia- lack of oxygen
Iron Deficiency Anemia
Sickle Cell Anemia
Thrombosis
clotting of blood
deep vein thrombosis
stroke
Hemophilia
disorder
blood doesn't clot properly
bleed too much
Hemorrhage
a profuse loss of blood
through a wound or other way
can cause anemia
Hyperglycemia
high levels of glucose in the blood
Lymphoma
cancer of lymph nodes
lymphocytes begin multiplying uncontrollably
forms tumors
