The lymphatic system supplements the cardiovascular system by absorbing excess tissue fluid, transporting it through lymphatic vessels, and returning it to the bloodstream. The lymphatic system also strengthens the immune system through lymph nodes and other lymphoid organs that filter lymph, destroy foreign substances, and produce lymphocytes and antibodies. A healthy lymphatic system is important for preventing the spread of microorganisms and diseases, and for proper immune function.

2. PREVIEW
*THE LYMPHATIC SYSTEM is functionally related to
cardiovascular system.
*THE LYMPHATIC SYSTEM strengthen the immune
system response by preventing the spread of disease-
causing microorganisms
Question to ponder:
***How do lymphatic system
supplement the Cardiovascular
system?
***Why is it important?
***How does it help my immune
system?

3. PARTS OF LYMPHATIC SYSTEM
I- LYMPHATIC VESSELS
- pick-up the excess tissue fluid called Lymph and
return it to the blood stream.
*Composed of:
lymphatics- make the lymph flow toward only in the
heart.
lymph capillaries- absorbs water and dissolved
proteins between tissue cells and blood capillaries
Right Lymphatic duct- drains the lymph from the
right part of the body.
Thoracic duct- drains lymph from the left side of the
body

4. Lymph Capillaries

5. II- LYMPH NODES
*Filter and cleans lymph.
*Has macrophages that engulf and destroy foreign
substances, and
*Has Lymphocytes( a type of white blood cell) that
fights and respond to foreign substances.
*its internal framework supports the multiplication
of lymphocytes.
*its outer part has follicles(collection of
lymphocytes) which produces plasma cells
that releases antibodies.

7. III- OTHER LYMPHOID ORGANS
*Spleen- Filters blood. It destroys worn out red-
blood cells and return some of their breakdown
products to the liver.
*Thymus -functions at peak level only during youth. It
produces thymosin that programs Lymphocyte.
*Tonsils-traps and remove bacteria entering the
throat.
*Peyer’s patches- found on the small intestines.
They capture and destroy bacteria before it
penetrate the intestinal wall.

10. DISEASES OF LYMPHATIC SYSTEM:
LYMPHEDEMA
*occurs due to an accumulation of lymphatic fluid
that results to swelling.

11. SPLENOMEGALY
enlarged spleen that develops due to a
viral infection.

12. TONSILLITIS-
*Infection of the tonsils.
*It become swollen and inflamed, leading to
a sore throat, fever, and difficulty and pain while
swallowing.

13. HOW TO MAINTAIN A HEALTHY
LYMPHATIC SYSTEM
A. Eat well
* Include fruits and vegetables in your diet, these
contain enzymes which are powerful lymph cleaners.
B. Drink plenty of water
* it prevents the build-up of toxins
* helps to flush them out of the system.
C. Exercise regularly
*The more you move, the more active your bodily
systems are.

14. * Regular exercise helps to keep formation of excess
cholesterol at bay .
*purges the body of harmful toxins and fortifies the immune
system, which in turn promotes a healthy lymphatic system.
D. Avoid stress
* Stress and depression hamper normal functioning of your
organs
* Maintain a positive attitude towards life.
E. Skin Brushing
* dry brushing of the skin, opens up clogged pores and
improves lymph flow * It
stimulates cell renewal by getting rid of the dead skin cells.

15. F. PRAY
The wisest way to become healthy!. But pray also
for the health of your soul for it is what truly matters! our
Physical self will rot but our Soul will be eternal! .
