During hemopoiesis a specific stem cell will differentiate into other stem cells resulting in all the different cellular components of blood. Which of the following is the name of this original stem cell? normoblast erythroblast hemocytoblast

hemocytoblast

During the process of erythropoiesis, all of the following are ejected from the developing erythrocyte except __________. nucleus hemoglobin organelles

hemoglobin

The process of blood clotting is called __________. hemostasis agglutination homeostasis

hemostasis

Erythropoietin is a chemical that is involved in starting the process of erythropoiesis. Erythropoietin is a(n) __________ produced by the __________. enzyme; liver vitamin; spleen hormone; kidneys

hormone; kidneys

Carbon monoxide is a deadly gas and binds to hemoglobin when inhaled. It creates problems because it binds to the same site as oxygen does, competing for the same binding site. This ultimately causes the erythrocyte to deliver carbon monoxide instead of oxygen to the tissues. Which of the following is the binding site for carbon monoxide? iron globin amino acid

iron

Oxygen binds to the __________ portion of hemoglobin. iron protein globin

iron

Leukocytes can be partially identified by looking at their nucleus. All leukocytes have just one nucleus, but some have several lobes to their nucleus. Which of the following does NOT have a multi‐lobed nucleus? basophil eosinophil lymphocyte

lymphocyte

Hemocytoblasts can differentiate and turn into stem cells called myeloblasts. Myeloblasts will then turn into all of the following leukocytes EXCEPT __________. lymphocytes neutrophils eosinophils

lymphocytes

Most leukocytes will leave the bloodstream and function to kill bacteria, etc., often times dying in the process. These leukocytes do not return to the bloodstream. Which of the following leukocytes are the only ones that can leave and return to the bloodstream? monocytes lymphocytes neutrophils

lymphocytes

Neutrophils are referred to as polymorphonuclear leukocytes because __________. they have many nuclei their nucleus can take on a variety of shapes some have a single nucleus and some have many nuclei

their nucleus can take on a variety of shapes

Megakaryoblasts develop from hemocytoblasts and are involved in the process of __________. hemostasis leukopoiesis thrombopoiesis

thrombopoiesis

Which of the following is the greatest component of plasma? ions water protein

water

20‐25%

Carbon dioxide binds the __________ portion of hemoglobin. iron heme amino acid

blood formation; a process of maintaining a steady state; blood clotting

Neutrophils are attracted to the site of an infection due to the process of __________. chemotaxis phototaxis hemotaxis

chemotaxis

Fibrinogen is a __________ that is transported via the plasma of blood. nutrient waste product clotting protein
