What are the stages of the red blood cell life cycle?

• A. Development, Functional, Senescence
• B. Production, Activity, Decline
• C. Growth, Maturity, Aging
• D. Formation, Function, Death

Answer: (A)

The stages of the red blood cell life cycle are accurately described as Development, Functional, and Senescence. In the Development stage, erythrocytes are produced in the bone marrow through a process known as erythropoiesis, where stem cells differentiate into mature red blood cells. The Functional stage refers to the period when the red blood cells are circulating in the bloodstream, carrying oxygen to tissues and organs while removing carbon dioxide. Finally, the Senescence stage marks the aging of red blood cells, which typically live around 120 days. During this phase, they lose functionality and are eventually removed from circulation by the spleen and liver, where they are broken down. This understanding of the life cycle is critical for phlebotomy technicians as it lays the foundation for understanding various hematological tests and conditions related to red blood cells, as well as their implications on patient health.
