Functions of Blood Transportation- oxygen carbon dioxide waste nutrients hormones Regulation- pH temperature influences water content of cells Protection- blood loss via clotting mechanisms foreign microbes via white cells Physical Properties of Blood viscous fluid viscosity is the resistance of a fluid to flow due to cohesion between its particles temperature is 38 o C (100.4 o F) pH range 7.35-7.45 (slightly alkaline) NaCl concentration of 0.9% volume in male, 5-6L, Female 4-5L 8% of the total body weight Components of Blood Formed Elements Erythrocytes (red blood cells) Leukocytes (white blood cells) Granular leukocytes neutrophils eosinophils basophils Agranular leukocytes lymphocytes monocytes Platelets (thrombocytes) Components of Blood Plasma consist of 91.5% water and 8.5% solutes (proteins, nutrients, gases, electrolytes, waste products,enzymes, and hormones) plasma proteins- proteins found and confined only in the blood Albumins - manufacture in the liver and is responsible for maintaining water balance in the blood. Consist of 55% of the total plasma proteins Globulins proteins divided into 3 classes according to electrophoretic separation

The indices are used to help in the differential diagnosis of anemia (a person's blood cannot carry as much oxygen as it should). Anemia A healthy person has an adequate number of correctly sized red blood cells that contain enough hemoglobin to carry sufficient oxygen to all the body's tissues. An anemic person has red blood cells that are either too small or too few in number . As a result, the heart and lungs must work harder to make up for the lack of oxygen delivered to the tissues by the blood.

Anemia is caused by many different diseases or disorders. The first step in finding the cause is to determine what type of anemia the person has. Red blood cell indices help to classify the anemias. Anemia (cont)
