Biconcave shape. Consists of 1/3 hemoglobin for transporting oxygen. Lack nuclei and mitochondria. Cannot divide
Red blood cells - RBCs
Hemoglobin without oxygen is called?
Deoxyhemoglobin
Hemoglobin with oxygen is called?
Oxyhemoglobin
Changes in red blood cell counts reflect what? 
Change in blood’s oxygen carrying capacity

Vitamin B 12
Folic acid
Nutritional requirement for hemoglobin synthesis
Iron
Condition in which oxygen carrying capacity of the blood is reduced due to deficiency of red blood cells or hemoglobin
Anemia
Worn out or damaged red blood cells are removed by which organs?
Spleen
Liver
Ruptured red blood cells are phagocytized by?
Macrophages
What happens to red blood cells when they are phagocytized by macrophages?
Hemoglobin separate into for subunits globin in chains with heme groups
Heme groups break down into iron and biliverdin
Iron is transported to red bone marrow by the protein transferrin 
Biliverdin is converted to bilirubin
Billy Verdon and Billy Rubin are excreted as bile pigments
Globin chains decompose into amino acids
Protect against disease. I have a limited life spans so they must always be replaced. Produced in red bone marrow under control of hormones interleukins and colony stimulating factors.
White blood cells (Leukocytes & WBCs)
Five types of white blood cells (BEN LM):
Basophils
Eosinophils
Neutrophils
Lymphocytes
Monocytes
Have granular cytoplasm, type of white blood cells:
Granulocytes
Do not have noticeable granules in cytoplasm, type of white blood cells:
Agranulocytes
Three granulocyte white blood cells (BEN):
Basophils
Eosinophils
Neutrophils
Two types of agranulocytes:
Lymphocytes
Monocytes
Function of white blood cells in order(1-5):
Positive chemotaxis
Diapedesis
Cellular adhesion molecules
Inflammatory response
Phagocytosis
Attraction of white blood cells to an infection site by chemicals released by damage cells is called?
Positive chemotaxis
White blood cells squeezed between the cells of a capillary wall and leave blood vessel then migrate towards infection site this is called?
Diapedesis
Proteins that direct leukocytes to injury sites are called
Cellular adhesion molecules
Reaction that restrict spread of infection promoted by basil fills I secretion of heparin and histamine involve swelling and increased capillary permeability this is called?
Inflammatory response
Engulfing and digestion of pathogens (neutrophils and monocytes are most mobile and active phagocytes) this action is called?
Phagocytosis
Type of white blood cell. Granulocyte with small light purple granules and acid base stain. First arrive at infection site. Strong phagocytes. Make up 54 to 70% of leukocytes elevated and bacterial infections
Neutrophils
Type of white blood cell that is a granulocyte with horse granules that stain deep red in acid stain. Bilobed nucleus. Moderate allergic reactions. Defend against parasitic worm infestations. Elevated and parasitic worm infestations and allergic reactions
Eosinophils
Granulocyte white blood cell with large granules that stain deep blue in basic stain. Release histamine to stimulate inflammation. Release heparin to stop blood from clotting. Less than 1% of leukocytes
Basophils
Largest of all the white blood cells. Agranulocyte with spherical kidney shaped oval and lobed nuclei. Leave bloodstream to become macrophages. 3 to 9% of leukocytes. Live for weeks to months. Phagocytize bacteria, dead cells,and debris
Monocytes
Agranulocyte white blood cells with large spherical nucleus surrounded by thin rim of cytoplasm. Important and immunity. May live for years
Lymphocytes
Two major types of lymphocytes
T cells
B cells
Type of lymphocyte that directly attacks pathogens and tumor cells
T cells
Type of lymphocyte that produces antibodies
B cells
High white blood cell count is called
Leukocytosis
Low white blood cell count is called
Leukopenia
Lists percentages of types of leukocytes which may change in particular diseases
Differential white blood cell count
Cytoplasmic fragments of megakaryocytes are called
Platelets (thrombocytes)
What hormone triggers hemocytoblast to produce platelets?
Thrombopoietin
High platelet count is called?
Thrombocytosis
Low platelet count is called
Thrombocytopenia
Platelets help in what process?
Hemostasis (stopping of bleeding) 
Causes smooth muscles and walls of broken blood vessels to contract
Serotonin
Protein that helps maintain pressure in vessels
Albumin
Clear liquid matrix. Liquid portion of blood making up 55% of blood volume. Comprise 92% of water. Transports nutrients gases hormones and vitamins. Regulate fluid and electrolyte balance and maintain pH
Blood plasma
Two most important blood gases
Oxygen
Carbon dioxide

Sodium and chloride
Three steps in hemostasis (stoppage of bleeding) 
Blood vessel (vascular) spasm
Platelet plug formation
Blood coagulation
Stimulated by cutting or breaking a small blood vessel. Smooth muscle and blood vessel contracts rapidly. Allows time for a platelet plug to form and blood to coagulate. Serotonin released from platelets causes vasoconstriction which further helps to reduce blood loss
Vascular spasm (blood vessel spasm)
Triggered by exposure of platelets to collagen. Platelets in here to rough surface to form a plug
Platelet plug formation
Most effective hemostatic mechanism occurs within 5 to 15 minutes. Forms blood clot in a series of reactions in which each step activates next one this is called a cascade. Consist of extrinsic and intrinsic clotting mechanism
