hematocrit (hct) Indices
• MCV • - CORRECT ANSWER - mean cell volume indicates RBC size
• MCH - CORRECT ANSWER - mean cell hemoglobin - weight of hemoglobin
contained in RBC

honeycomb-like structure
• More than 100 times blood cells in your ———- than there are people in the world! -
CORRECT ANSWER - Bone Marrow
Bone marrow is located within - CORRECT ANSWER - within the cavities of the cortical
bones

Red marrow - CORRECT ANSWER - hematopoietically active marrow Produces cells
Yellow marrow - CORRECT ANSWER - hematopoietically inactive marrow composed
primarily of adipocytes (fat cells)
Can return to active under right contions (example hemolysis) - CORRECT ANSWER -
Yellow marrow

Blood & nutrients are supplied by the - CORRECT ANSWER - periosteal arteries that
coil around the central vein, passing along the bone canal
sinuses - CORRECT ANSWER - • Sinus is a venous vessel found in the RES that is
larger than a capillary but smaller than a vein
Sinuses hook up to - CORRECT ANSWER - larger veins and return into main circulation
Bone Marrow Blood Flow - CORRECT ANSWER - Blood & nutrients are supplied by
the periosteal arteries that coil around the central vein, passing along the bone canal - Branches
and forms capillaries then sinuses
Red Marrow Composed of - CORRECT ANSWER - extravascular cords that contain all
of the developing blood cell lineages, stem and progenitor cells, adventitial cells, and
macrophages
Composed of extravascular cords - CORRECT ANSWER - Red Marrow
Red Marrow - Cells are in - CORRECT ANSWER - semi-liquid cords or wedges between
sinuses supported by trabeculae of spongy bone and reticular adventitial cells Cells develop in
specific niches within the cords

Location of Cell Development RBCS - CORRECT ANSWER - develop in small clusters
adjacent to the outer surfaces of the vascular sinuses
