Study Notes
Hematology is a branch of medicine that focuses on blood disorders, including blood cells and their formation. Blood cells play various roles in our body and can be grouped into three main types: red blood cells (erythrocytes), white blood cells (leukocytes), and platelets. Red blood cells carry oxygen from the lungs to other parts of your body. White blood cells help fight infection. Platelets form clots to stop bleeding if you get cut or injured. They also support healing by releasing chemicals that promote tissue growth.
Hematopoiesis refers to the process of creating new, mature blood cells from stem cells found inside bone marrow. This happens throughout life, although it's more active during certain periods like infancy and adolescence. There are two major forms of hematopoiesis: myeloid and lymphoid hematopoiesis. Myeloid hematopoiesis produces the majority of adult blood cell progenitor cells. Lymphoid hematopoietic cells give rise to B cells, T cells, natural killer cells, and dendritic cells. These cells function together to protect the body against disease and infection.
In summary, hematology deals with blood cells and their production through hematopoiesis. It encompasses the study of diseases related to blood and its components, such as anemia, leukopenia, thrombosis, hemorrhage, etc. Understanding these processes helps doctors diagnose and treat diseases linked to abnormalities in blood cell counts and characteristics.
Explore the fundamentals of hematology, the branch of medicine that focuses on blood disorders and the three main types of blood cells: red blood cells, white blood cells, and platelets. Learn about hematopoiesis, the process of creating new blood cells from stem cells, and the two main forms: myeloid and lymphoid hematopoiesis. Discover how blood cells play vital roles in our body and how understanding these processes helps in diagnosing and treating blood-related diseases.
