Hematology is the study of blood, blood components, and blood-forming organs and their impact on an individual’s health and well-being. The hematological system is important for transporting and regulating different functions within the body, as well as for ensuring that cells receive the nutrients and oxygen they need to function. The hematology system also plays an important role in waste removal and immune function. Dysfunction within the hematology system can contribute to numerous health alterations, as the body relies on coordinated physiological processes to help maintain homeostasis. Homeostasis is the body’s ability to maintain stable internal conditions and function despite changes in the external environment.[1] It is a self-regulating process that ensures the body’s internal environment remains within a narrow range, allowing cells and organs to function optimally. When homeostasis is disrupted or unable to be maintained, health alterations may arise.
