& Smith: Ch 30 Introduction to the
Hematopoietic and Lymphatic Systems
test Questions
Hematopoiesis - answer the manufacture, and development of blood cells
Lymphocytes - answer specific types of white blood cells
Bone marrow - answer the soft tissue that fills spaces in the interior of the long bones
and spongy bones of the skeleton, manufactures blood cells
Red marrow - answer found in the ribs, sternum, skull, clavicles, vertebrae, proximal
ends of the long bones, and iliac crest, manufactures blood cells and hemoglobin
Yellow marrow - answer consists of fat cells and connective tissue, does not participate
in the manufacture of blood cells, unless under intense stimulation
Plasma - answer liquid, or serum, portion of blood that does not contain blood cells
Pluripotential stem cells - answer undifferentiated precursors in the bone marrow from
which all blood cells develop
Erythrocytes - answer red blood cells, circulates in blood for approx 120 days
Leukocytes - answer white blood cells; life span only 1 - 2 days, thus demand for
production is continuous
Platelets - answer aka thrombocytes, help control bleeding by forming a loose blood
clot; life span approx 7.5 days
Physical characteristics of erythrocytes: - answer flexible, anuclear, bioconcave disks
covered by a thin membrane through which O2 and CO2 pass freely
Erythropoietin - answer a hormone secreted by the kidneys that stimulates the bone
marrow to produce erythrocytes
Why is iron important? - answer the basic nutritional component of heme in hemoglobin
Why is protein important? - answer the building block of hemoglobin and the exzymes
involved in red blood cell production
