Patients

The American Society of Hematology has developed the resources in this section to educate the public about the importance of healthy blood and to raise the awareness of common blood diseases, such as anemia, bleeding and clotting disorders, and blood cancers.

Blood is a specialized body fluid. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues, forming blood clots to prevent excess blood loss, carrying cells and antibodies that fight infection, bringing waste products to the kidneys and liver, which filter and clean the blood, and regulating body temperature.
