BLOOD AND ITS COMPONENTS
Physical Characteristics of Blood
* Thicker (more viscous) than water and flows more slowly than water * Temperature of 100.4 degrees F
* pH 7.4 (7.35-7.45)
* 8 % of total body weight
* Blood volume
* 5 to 6 liters in average male
* 4 to 5 liters in average female
FUNCTIONS OF BLOOD
* Transportation
* O2, CO2, metabolic wastes, nutrients, heat & hormones * Regulation
* helps regulate pH through buffers
* helps regulate body temperature
* Protection from diseases
BLOOD COMPONENTS
* 55% plasma: 7 to 8% dissolved substances (sugars, amino acids, lipids & vitamins), ions, dissolved gases, hormones and 45% erythrocytes

BLOOD PLASMA
* Composed of approximately 90 percent water
* Includes many dissolved substances
* Nutrients, Salts (metal ions)
* Respiratory gases
* Hormones
* Proteins and Waste products
FORMED ELEMENTS OF BLOOD
* Red blood cells ( erythrocytes )
* White blood cells ( leukocytes )
* granular leukocytes
* neutrophils
* eosinophils
* basophils
* agranular leukocytes
* lymphocytes = T cells, B cells, and natural killer cells * monocytes
* Platelets (special cell fragments)
Erythrocytes (Red Blood Cells)
* Function: carry oxygen
* Anatomy of circulating erythrocytes
* Biconcave disks
* Essentially bags of hemoglobin
* Anucleate (no nucleus)
* Contain very few organelles
* Outnumber white blood cells 1000:1
HEMOGLOBIN
* Iron-containing protein
* Binds strongly, but reversibly, to oxygen
* Each hemoglobin molecule has four oxygen binding sites
* Production of abnormal hemoglobin can result in serious blood disorders such as thalassemia and sickle cell anemia. Erythropoiesis: Production of RBCs
* Erythropoiesis occurs in...
