Functions of Lymph system |
-Transport of lipids and lipid soluble vitamins -Lymphocyte development - immune response |
|
|
Natural killer cells |
large granular lympocytes, dont stimulate antigens |
|
|
Lymphopoiesis |
Process of lymphocyte development |
|
|
where do lymphocytes start life? |
Red bone marrow |
|
|
Thymus (location) |
Behind Sternum
|
|
|
Main lymphatic Organs |
Thymus, lymph nodes, and spleen |
|
|
lymph nodes |
lymphocytes hang here |
|
|
Spleen |
1. initiates immune response when antigens in blood 2. Serves as reservoir for erythrocytes and platelets 3. phagocytizes old defective erythrocytes - has capsule |
|
|
Lymph |
left over interstitial fluid & solutes enter lymph vessels then its called lymph. - eventually returns to blood stream |
|
|
interstitial fluid |
in the tissues - named based on where it is |
|
|
Transport of lipids and lipid soluble vitamins |
lipids dissolve in lymph first and then go to bloodstream |
|
|
Immune response |
B & T cells - put interstitial fluid back in blood stream |
|
|
Lymphatic Capillaries |
only flow in one direction, cells overlap to only allow in flow |
|
|
Lymph vessels |
- interstitial fluid becomes lymph - muscle movement moves lymph by contracting - take lymph toward right lymphatic duct & thoracic duct |
|
|
Right lymphatic duct |
empties in to right subclavian where it turns into brachiocephalic vein. 1/4 of body (right chest, Right arm and R. side head) |
|
|
cisterna chyli |
collects lymph from both legs |
|
|
Thoracic duct |
empties into L subclavian where it turns into brachiocephalic vein - collects lymph from lower limbs and entire left side of the body (3/4 of body) |
|
|
Helper T lymphocytes |
stimulate cytotoxic T cells and B cells |
|
|
Cytotoxic T lmphocytes |
Make chemicals to attack infected or cancerous cells. - come in direct contact with foreign cells |
|
|
B lymphocytes |
become plasma cells that make antibodies - stay in bone marrow for maturing process |
