Examples of Hematology


The hematology is the discipline that studies everything related to blood and possible diseases. In addition, it also covers treatments, investigations and the analysis of hematopoietic organs.

As we know, blood is in a liquid that travels throughout the body through veins, arteries and organs until it reaches every cell and tissue in the body. Each adult human being has about 5 liters of blood , and it is made up of red blood cells, white blood cells, and platelets, all of which are suspended in plasma.
  • Red blood cells . They are responsible for transporting hemoglobin, whose function is to collect oxygen and carry it throughout the body.
  • White blood cells The main function is to serve in the defense of the body when infectious organisms attack. There are two types: neutrophils and lymphocytes.
  • Platelets . They are very important cells when a blood vessel ruptures, since they are responsible for obstructing them to prevent bleeding or that these are of a greater proportion.

What do you study?

As we mentioned before, hematology studies the diagnosis of diseases, treatments and evaluation of organs related to the circulatory system.

“Hematology” should not be confused with “hemogram”, the first term refers to the discipline that studies blood and the second to a medical analysis that is done to know the status of some values ​​related to blood.

The professional in charge of conducting these studies and investigations is the hematologist and can identify and prescribe treatments for anemia, thrombophilia, neutropenia, hemophilia , myelodysplastic syndrome , among other common diseases. If the blood count shows signs of other diseases such as cancer, it is necessary that an oncologist treat the patient.

The patients of a hematologist can be children, adolescents, adults and the elderly, of course, there is a pediatric hematologist profile who performs these same studies in children.
