What process is responsible for the production of red blood cells? - Answers Erythropoiesis
What hormone stimulates erythropoiesis? - Answers Erythropoietin
What is hemopoiesis? - Answers The process of blood cell production.
What is a hematopoietic stem cell (HSC)? - Answers An originator cell common to all blood cell types.
What are the three specific types of hematopoiesis? - Answers Erythropoiesis, leukopoiesis, and
thrombopoiesis.
Where are new red blood cells produced in adults? - Answers In the bone marrow of various bones.
What are reticulocytes? - Answers Immature red blood cells that develop into erythrocytes.
What is the primary function of leukocytes? - Answers To defend the body from disease-causing
microorganisms.
From what do all white blood cells arise? - Answers Multipotent stem cells, or hemocytoblasts.
What do myeloid stem cells develop into? - Answers Myeloblasts and monoblasts, leading to various
types of white blood cells.
What are the main functions of blood? - Answers Transporting oxygen, nutrients, and waste;
regulating body temperature and pH; and protecting against disease.
What is the role of enzymes in blood plasma? - Answers To catalyze chemical reactions and increase
reaction rates.
What happens to old or damaged RBCs? - Answers They are removed from circulation by the spleen
and liver.

basophils
What do monoblasts differentiate into? - Answers Monocytes, which ultimately become macrophages
What types of cells do lymphoblasts differentiate into? - Answers T lymphocytes, B lymphocytes, or
natural killer cells
What are granulocytes? - Answers A collective term for neutrophils, eosinophils, and basophils that
fight infection
What do hemopoietic growth factors regulate? - Answers The proliferation and differentiation of
hematopoietic progenitor cells in the bone marrow
What are hematopoietic progenitor cells (HPCs)? - Answers Immature cells that develop from
hematopoietic stem cells and differentiate into mature blood cells
What is erythropoietin and where is it synthesized? - Answers A hormone synthesized by the kidneys
and liver in response to hypoxia
