Bright red
Color of blood that is unsaturated with oxygen
Dark red
Total blood volume of the male
5-6L
Total blood volume of female
4-5L
The branch of science concerned with the study of blood, blood-forming tissues, and the disorders associated with them
Hematology
Most common procedure for collecting blood
Venipuncture
Method of collecting blood from the artery
Arterial puncture/stick
Which layer consists of white blood cells and platelets
Buffy coat layer
A straw-colored liquid that is about 91.5% water and 8.5% solutes, most of which are proteins
Blood plasma
Proteins that are confined to blood
Plasma proteins
Types of plasma proteins that are produced during certain immune responses.
Antibodies or immunoglobulins
What are the three principal components of the formed elements of the blood
RBC
WBC
Platelets
Transport oxygen from the lungs to body cells and deliver carbon dioxide from body cells to the lungs
RBC/erythrocytes
Protect the body from invading pathogens and other foreign substances
WBC/leukocytes
Fragments of cells that do not have a nucleus. Release chemicals that promote blood clotting when blood vessels are damaged
Platelets
The percentage of total blood volume occupied by RBCs is called
Hematocrit
Disorder in which the percentage of RBCs is abnormally high, and the hematocrit may be 65% or higher
Polycythemia
The process by which the formed elements of blood develop is called
Hemopoiesis
A highly vascularized connective tissue located in the microscopic spaces between trabeculae of spongy bone tissue
Red bone marrow
These cells have the capacity to develop into many different types of cells. Derived from mesenchyme and are about 0.05-0.1% of red bone marrow cells
Pluripotent stem cells/hemocytoblasts
The enlarged and leaky capillaries where blood from nutrient and metaphyseal arteries passes through
Sinuses
Withdrawal of a small amount of red bone marrow with a fine needle and syringe
Marrow aspiration
Removal of a core of red bone marrow with a larger needle
Bone marrow biopsy
These types of cells begin their development in red bone marrow and give rise to RBC, platelets, monocytes, neutrophils, eosinophils, basophils, and mast cells
Myeloid Stem cells
These types of cells begin their development in red bone marrow but complete it in lymphatic tissues. Gives rise to lymphocytes and natural killer cells
Lymphoid stem cells
Cells that are no longer capable of reproducing themselves and are committed to giving rise to more specific elements of blood
Progenitor cells
Cells that undergo several cell divisions, developing into the actual formed elements of blood
Precursor cells or blasts
Hormones that regulate the differentiation and proliferation of particular progenitor cells
Hemopoietic growth factors
Increases the number of red blood cell precursors
Erythropoietin
Hormone produced by the liver that stimulates the formation of platelets from megakaryocytes
Thrombopoietin
