Red Blood Cells in Health and Disease.

Red blood cells (RBCs) play a crucial role in the normal functioning of the human body, primarily through their ability to transport oxygen and carbon dioxide. Various diseases, including anemia and other hemolytic disorders, can arise when there is an abnormality in RBC structure or function. The pathophysiology of other conditions, such as cancer and cardiovascular disease can also involve changes in RBCs. Advances in RBC research have led to a better understanding of their structure, function, and pathophysiology. The COVID-19 pandemic has also highlighted the critical role of RBCs in disease pathology, with research suggesting that RBCs may be directly affected by the virus. This review provides a comprehensive overview of the current state of RBCs in health and disease, including recent advances in diagnosis, treatment, and the role of RBCs in disease pathology.
