Answers.
Hematology - Answer The study of blood
Hematopoiesis - Answer The formation of blood cells
Hematopoietic System - Answer The organs that produce, store or circulate blood cells
Where is the major production of red blood cells - Answer bone marrow
What is the makeup of blood - Answer cells, water, nutrients, electrolytes and hormones/enzymes
Where are waste products removed from the blood in the body - Answer Liver and Kidney
3 types of blood cells - Answer red blood cells, white blood cells, platelets
Purpose of RBC - Answer carry oxygen
Purpose of WBC - Answer protect against organisms/infection, also inflammation
Purpose of platelets - Answer initiate coagulation
What is hemoglobin? - Answer protein molecule in a red blood cell
,what is the job of a hemoglobin molecule? - Answer to transport oxygen from capillary beds of the
lungs to the body tissues.
Percentage of water and hemoglobin in RBC. - Answer Water 60-65% and hemoglobin 30-35%
How many oxygen molecules can attach to each hemoglobin molecule? - Answer 4 oxygen molecules
How many hemoglobin molecules can one RBC have? - Answer 400,000 hemoglobin molecules
what other substance can give tissues oxygen? - Answer plasma, it contains dissolved particles of
oxygen
What is the primary carrier of oxygen? - Answer Hemoglobin molecule
What is oxygen saturation? - Answer The percentage of oxygen that is bound to hemoglobin.
How is oxygen saturation measured - Answer a pulse oximeter
PaO2 - Answer Partial pressure of oxygen
Level of PaO2 in the lungs - Answer high, oxygen binds readily
level of PaO2 in body tissues - Answer low, oxygen is released
What happens to the hemoglobin molecule if the body has a low pH? - Answer Tissues are hypoxic, so
the molecule opens and releases only the 1st oxygen molecule, causing a increase in the enzyme
2,3diphosphoglycerate (2,3 DPG) allowing more oxygen to be released
Temperature increase causes oxygen to... - Answer release oxygen, generally in tissues
, What must occur in the lungs to bind oxygen - Answer High pH, low DPG and low temperature
what must occur in the tissue to release oxygen - Answer Low pH, high DPG and high temperature
Abnormal Heme groups cannot..... - Answer carry oxygen
What is carboxyhemaglobin? - Answer it pushes out oxygen, because hemoglobin has 240X affinity for
carbonmonoxide (CO2) than oxygen. blood usually appear an unusual bright red.
What is Methemoglobin? - Answer When an iron molecule (Fe) is oxidized to Fe3, causing the blood to
appear brown in color. (Tylenol toxicity in cats)
Function of RBC - Answer carry oxygen to the tissues via hemoglobin
Does a RBC have a nucleus - Answer RBC is anuclear
Define erythropoiesis - Answer production/formation of red blood cells
Where does the production of RBC occur? - Answer bone marrow
What is the maturation time of a RBC - Answer 5 days
What is hypoxia? - Answer an increase in erythropoietin hormone
Where is erythropoietin made? - Answer in the kidney
what does erythropoietin do? - Answer Stimulates stem cells differentiation in bone marrow, causes
early reticulocyte release and causes hemoglobin synthesis
