|
Right Lymphatic Duct |
Drains right arm, torso and head (right subclavian vein) |
|
|
Thoracic duct |
Drains other 3/4 of the body (left subclavian vein) |
|
|
Primary Lymphatic Organs |
Organs involved in the formation & maturation of lymphocytes (Thymus: t-cells, red bone marrow: b-cells) |
|
|
Secondary Lymphatic Organs |
Organs involved in housing lymphocytes (Tonsils, Lymph nodes, Spleen, MALT) |
|
|
Immunocompetence |
The ability to recognize and respond to antigens |
|
|
Lymphatic capillaries |
anchored w/ anchoring filament have 1-way valves large diameter easier to pass through |
|
|
Lacteals |
absorbs fat in small intestine fluid called "chyle" - milky, full of fat |
|
|
Functions of the Lymphatic system |
Defense Fluid balance (3L back into blood) Fat absorption (digestive system) |
|
|
What affects lymph movement |
- skeletal muscle contraction - thoracic pump (respiratory) - pulsatile movement of capillaries/arteries - smooth muscle contraction (larger lymph vessels) |
|
|
Structure of Lymph node |
1. cortex: contain lymph nodules: a germinal center (b-cells & macrophages) & a mantle zone (t-cells & macrophages) 2. medulla: medullary cords: CT that supports b-cells, t-cells and macrophages |
|
|
Locations of tonsils |
Pharyngeal: aka adenoids Palatine: back of throat Lingual: base of tongue |
|
|
Parts of the spleen |
White pulp: T-cells, b-cells, macrophage Red pulp: RBC, platelets, macrophages, b-cells (serves as a blood reservoir) |
|
|
MALT |
Mucosa Associated Lymphatic Tissue - Larger groups of lymphatic nodules found w/in respiratory and digestive tract mucous |
|
|
Peyers Patch |
MALT found in the small intestine |
