Lymphatic System

2. Arteries

3. It is a one way system back to the heart
See page 745

4. Interstitial fluid that enters the lymphatics (lymphatic vessels)

5. Right Lymphatic Duct:
Drains lymph from the right upper arm and right side of head and thorax

6. Thoracic Duct:
Much Larger, Drains rest of body
See page 747

7. Internal Jugular Vein
Subclavian Vein
At the Junction of
See page 747

8. Red Bone Marrow
T Lymphocytes – Killer T, Helper T
B Lymphocytes - Antibodies

9. Body Protection
Immune Response (activate T cells)

10. Proliferation site for lymphocytes
Ideal surveillance vantage point

11. Embedded in connective tissue
Inguinal, axillary, cervical

12. Lymph filters – MAC’s
Activate Immune System

13. Lymphocyte proliferation
Filter system

14. Stores breakdown products of RBCs
Erythrocyte production in fetus
Stores blood platelets

15. T cell maturation, become immunocompetent
T cell maturation, become immunocompetent. Does not directly fight antigens
Stroma secretes hormones for T cells to become immunocompetent.

16. Gather/Remove pathogens

17. Peyer’s Patches, appendix?
Part of MALT – Mucosa-Associated Lymphatic Tissue
Help patrol intestines and help generate memory
