Q

Bone Marrow

A

The soft material filling the cavities of the bones, made up of a meshwork of connective tissue, the meshes being filled with marrow cells, which consist variously of fat cells, nucleated hematopoietic cells (precursors of the mature cells of the blood), mature blood cells, and tissues cells. Yellow bone marrow is bone marrow of the kind in which the fat cells predominate. Red bone marrow is marrow which is the site production of red blood cells, white blood cells, and platelets.

Q

Hemorrhage

A

The escape of blood from the vessels; small hemorrhages are classified by size as petechiae (very small), purpura (up to 1 CM), and ecchymoses (larger). The accumulation of blood within a tissue is called a hematoma. Spontaneous h. - Hemorrhage occurring without overt provocation.

Q

Homeostasis

A
