What area of the body is devoid of lymphatics?
|
CNS
|
|
Which areas of the body have dense lymphatic networks?
|
Dermis, mucous membranes
|
|
What are the 4 main parts of the lymphatic system?
|
1. Lymph
2. Lymphatic vessels 3. Lymphoid tissues & organs 4. Cells of immune system |
|
What is the primary function of the lymphatic system?
|
Production, maintenance & distrubution of lymphocytes to detect problems, reach site of injury/infection
|
|
What are other functions of the lymphatic system? (2)
|
1. remove excess fluids from body tissues
3. Absorb FA & transport of fat, chyle to circulatory system |
|
When does tissue fluid become lymph?
|
Once it has entered lymphatic capillary
|
|
How is lymph fluid formed?
|
-Fluid leaks from blood capillaries into interstitial spaces to supply cells w/ nutrients
-Excess fluid not reabsorbed by venous capillaries enter lymph capillaries by increased interstitial pressure (hydrostatic pressure of tissue fluid) |
|
What percent of interstitial fluid returns to venous capillaries?
|
90% due to hydrostatic pressure of interestitial fluid & oncotic pressure inisde capillaries
|
|
10% of interestitial fluid returns to circulatory system via lymphatics due to?
|
Osmotic pressure exerted by proteins in blood plasma
