Hematologic Disorders 1 Flashcards
These 3 systems are all linked
- hematological
- lymphatic
- immune
These are also a part of the hematopoietic system
lymph nodes
hematopoietic =
blood forming
All lymphoid organs link these systems
- hematologic
- immune
How do lymphoid organs link the hematologic and immune systems?
They are sites or residence, proliferation, differentiation, or function of
- lymphocytes
- mononuclear phagocytes
Disruption of hematologic system results in circulatory disorder and are characterized by:
- edema
- congestion
- infarction
- thrombus
- lymphedema
- lymphadenopathy
- splenomegaly
edema =
excess fluid in interstitial tissues or body cavities
congestion =
excess blood within vessels of an organ or tissue
infarction =
area of necrosis
thrombus =
solid mass of clotted blood
lymphedema is this type of disorder
hematolymphatic
lymphedema =
obstruction of lymph vessels or nodes
lymphadenopathy =
abnormal enlargement of lymph nodes
How should lymph nodes feel?
- rubbery
- mobile
- small (≤ 1 cm)
splenomegaly =
enlargement of the spleen
