What are the functions of blood?
distribution ( transportation) , regulation, protection
What are the names of the 5 types of WBC?
Granulocytes - Neutrophils, Eosinophils, Basophils
Agranulocytes- Lymphocytes, Monocytes
What are the names of the electrolytes commonly found in blood?
Sodium, Potassium, Chloride, Bicarbonate, Calcium, Magnesium, Phosphate

1000 to 1
What are 3 characteristics of blood?
Biconcave surface area
1/3 hemoglobin
Outnumber WBC 1000:1
Function to carry oxygen
Lack a nuclei & mitochondria
Low Blood Oxygen Cycle ( Long Term)
Low blood oxygen is detected by the Kidneys & Liver
The protein HIF (Hypoxia- inducible factor ) stimulates the Kidneys & Liver to produce the hormone Erythropoietin (EPO) into the bloodstream
EPO travels through the bloodstream to the Red Bone Marrow
Which then stimulates the increased production of RBC
Increased amounts of RBC mean O2 (oxygen) carrying abilities is increased
Oxygen levels return to normal
Kidneys detect that, and stop producing extra EPO
Low blood oxygen stimulates the Kidneys to produce what hormone?
Erythropoietin
Regulation of Erythropoiesis Factors
Too few RBC = tissue hypoxia
Too many RBC = increased blood viscosity ( thickness)
Balance of RBC production and destruction depends on
hormonal controls and adequate supplies of iron, amino acids, and B vitamins
RBC live for how long?
About 120 days
What are the causes of Aplastic Anemia?
Damaged Bone Marrow, Toxic chemicals, Radiation
