Extramedullary hematopoiesis Flashcards
Blood cell production in hematopoietic tissue other than bone marrow.
Extramedullary Hematopoiesis
mediates between the progenitors and binding to the stroma
Proteoglycan/Glycosaminoglycan
Adhesion molecules of extramedullary hematopoiesis: (5)
a. Fibronectin
b. Collagen
c. Laminin
d. Heonectin
e. Thrombospondin
Macrophages of the liver removing cellular and foreign debris from blood and for Protein synthesis
Kupffer cells
Allows plasma to have direct access to the hepatocytes
Epithelial cells
Functions of liver aside from being the major site of blood cell production during the hepatic stage: (5)
- Synthesizes various transport proteins
- Stores essential minerals and vitamins that are used in synthesis of DNA
and RNA - Conjugates bilirubin from Hemoglobin degradation
- Transports bilirubin to the small intestine for eventual excretion
- Optimal for gathering, transferring and eliminating substances via the
bile
Largest lymphoid organ
Spleen
Other term for spleen
Reticuloendothelial organ
Primary function of the spleen
a. Lymphopoiesis
b. Phagocytosis
Graveyard of senescent blood cells
Spleen
Spleen is vital and essential.
a. True
b. False
b. Vital but not essential
Organs of the lymphatic system located along the lymphatic
capillaries
Lymph nodes
Oval shaped structures distributed throughout the body connected
by lymphatic vessels
Lymph nodes
Fluid carried by the lymph nodes
Lymph

Lymph nodes act as filters to remove foreign blood contaminants.
Superficial lymph nodes: (4)
- inguinal
- axillary
- cervical
- supratrochlear
Deep lymph nodes: (2)
- Mesenteric
- Retroperitoneal
This is formed by an outer capsule of the lymph nodes
Trabeculae
Responsible for normal development of some of the lymphocytes
Thymus
Where is thymus located?
Neck
