3. WHAT IS LYMPH
Lymph pale fluid is derived from the interstitial fluid( lies
in the interstices of all body tissues) is collected through
lymph capillaries contains more wbc then plasma enter
through afferent lymphatic vessels in one direction.
The word lymph is derived from the latin name
”lympha”(means clear fluid)
It contains also clotting factors and clots on standing in
vitro
Three kinds of lymph ,1)peripheral,2)transport,3)central
7. LYMPH PRODUCTION
Fluid efflux normally exceeds influx across the
capillary walls ,but the extra fluid enters the lymph
and drain through them back into the blood. This
keeps the interstitial fluid pressure from rising and
promotes the turnover of tissue fluid the normal 24
hours lymph flow is 2-4L
9. Lymph circulation
Lymph carry with lymph
capillaries in one
direction.Lymph
capillaries carry the
lymph to lymphatic
vessels,which is one blind
ended vessels and
permeable to proteins
even cells.
10. LYMPH CIRCULATION
Lymph circulation includes :
1. lymph
2. Lymphatic capillaries
3. Lymphatic collecting vessels
4. Lymphatic trunks and ducts
Presence no central pump.
Presence valve for one way
directed flow of lymph.
12. Lymph functions
Support of constant level of volume and
components of tissue fluid.
Transport of nutritive substances from
digestive tracts on venous system.
Barrier-filter function.
It pick up bacteria and bring them to lymph
nodes ,lymph nodes destroy them.
13. Lymph function
Metastatic cancer cells can be transported
via lymph
It transports fat,lipid from the digestive
system(beginning in the lacteals) to the blood
via chylomicrons
Take place in immunology reaction
14. Lymph function
Plasma cells produce antibodies to
antigens in the lymph.
Antibodies,lymphocytes and monocytes
are eventually returned to the blood via
subclavian veins.
15. DiseasesThere are some diseases which are occurring for
lymph,lymph nodes,lymph vessels dysfunction or
inflammation.
1. LYMPHANGITIS
2. FILARIASIS
3. LYMPHEDEMA
4. LYMPHADENOPATHY
5. LYMPHOMAS
6. LYMPHADENITIS
16. Inflammation of the
lymph vessels.
Commonest cause
bacteria called
streptococcus
pyogenes.
Lymph vessels appear
as red streaks through
the skin.
LYMPHANGITIS
18. LYMPHEDEMA
Occurs due to
accumulation of
lymphatic fluid in the
inerstitial tissue.
Sometimes canbe
appreciated after
wearing tight clothing
or jewellery on affected
limb
