 * HEMATOLOGY **

What is hematology? Well, the study of the blood. There are over 60,000 miles of blood vessels in one human body! Also, blood accounts for 7% to 8% of your body weight. One might say, "Blood makes the body go round!" Let's take a look at some important information about the formed elements of blood and how important blood is to maintaining function and homeostasis. __**I. Functions of the Circulatory System **__ *There are three main areas of the functions of the circulatory system which are transportation, regulation and protection *There are three categories of substances needed for cellular metabolism through transportation and they are respiratory, nutritive and excretory. *Through regulation hormonal and temperature are the key focus *Protection in the circulatory system covers clotting and immunity

The formed elements of blood contain two main blood cells. *Contain 280 million hemoglobin molecules *Known as red blood cells (RBC) *RBC are quite abundant when compared to white blood cells *Flat, biconcave discs *Unique shape *Lack nuclei and mitochondria *Responsible for transporting oxygen *Only life for 120 days in the body *Known as white blood cells (WBC) *Have a nuclei and mitochondria (unlike RBC) *Able to transport through pores in capillary walls to a site of infection *Almost impossible to see under a microscope unless stained with eosin or a basic stain *Two main categories of leukocyctes, granular and nongranular based on granules in the cytoplasms *Granulocytes include neutophils, eosinophil and basophil *Agranulocytes include monocytes and lymphocytes
 * II. Two Main Blood Cells **
 * A. Erythrocytes **
 * B. Leukocytes **

The smallest of the formed elements *Also known as thrombocytes *Actual fragments of large cells called megakaryocytes *Key role in blood clotting in the body *Lack nuclei *They survive in the body for 5 to 9 days before being destroyed by the liver and spleen *Platelets work together to release the chemical serotonin in a blood clot which reduces the blood flow to an injured location
 * III. Platelets **

__**APPLICATION:**__ At the hospital I work at we have a Hematology department. It is also refereed to as the dialysis department. Our pharmacy department helps with treatment plans and prepares and orders the very expensive drugs that are used during dialysis. The kidneys are responsible for filtering the blood in the body and when a patient comes in for dialysis they have their blood filtered by a machine. By dialysis the patient is able to help maintain proper filtration of the blood and can maintain their health. If untreated, people can eventually die from kidney failure. A lot of patients come in multiple days during the week to receive dialysis.

Essential Questions: **ABO Blood Typing Chart** __ Blood Type Cell Antigen Antibodies Donor __ <span style="color: #ff0040; font-family: 'Lucida Sans Unicode','Lucida Grande',sans-serif; font-size: 120%;"> When blood types are not compatible and are shared agglutination occurs which is clumping of the blood. Blood type "O" is known as the universal blood donor because it is compatible with all blood types. "AB" blood is known as the universal recipient because it can recieve any type of blood.
