Chapter 18 Blood Composition
What are the three functions of blood?
Transportation, Regulation, and Protection
What makes up the formed elements of the blood?
Red Blood Cells
White Blood Cells-
-Granular leukocytes, neutrophils, eosinophils, basophils.
-Agranular leukocytes, T and B lymphocytes and natural killer cells, monocytes.
What is the percentage of total blood volume occupied by RBCs?
Hematocrit
What is the normal range of hematocrit for adult females? Adult males? women:38-46% males: 40-54%
What does a significant drop in hematocrit indicate?
Anemia, a lower than normal number RBC's
What does an abnormally high percentage of RBC's indicate? polycythemia. What are causes of polycythemia? abnormal RBC production, tissue …show more content…
The process by which the formed elements of blood develop.
What is the primary site of hemopoiesis?
Red bone marrow.
What is thrombopoietin?
TPO, is a hormone produced by the liver that stimulates the formation of platelets from megakaryocytes.
What does Erythropoietin?
EPO, increases the number of red blood cell precursors.
What are erythrocytes? red blood cells
What is the oxygen carrying protein?
Hemoglobin
In addition to oxygen, hemoglobin also carries carbon dioxide. What percentage of the total carbon dioxide is carried by hemoglobin and what happens to the remaining carbon dioxide?
23% of the carbon dioxide is carried by hemoglobin and the remaining is dissolved in plasma or carried as bicarbonate ions.
Besides transporting oxygen and carbon dioxide, what else does hemoglobin play a role in? regulation of blood flow and blood pressure.
How long do RBC's live and why? about 120 days because of the wear and tear their plasma membranes undergo as they squeeze through blood capillaries.
What is erythropoiesis?
The production of RBC's
What is hypoxia? cellular oxygen deficiency
What are leukocytes? white blood cells
Which WBC's are included under granular leukocytes, agranular
