1. Carry oxygen to tissues
2. Maintain the chemical integrity of hemoglobin
3. Assume a flexible disk shape that allows for optimal filling and transport to body tissues
4. Are terminally differentiated
Rationale: Carry oxygen to tissues. This is a primary function of blood as a transport system. Maintain the chemical integrity of hemoglobin. The function of the red blood cells is to become filled with hemoglobin, maintain the integrity of hemoglobin, and distribute it to the body's tissues. Assume a flexible disk shape that allows for optimal filling and transport to body tissues. The shape facilitates filling and transport of nutrients. Are terminally differentiated. Red blood cells can never divide. Have a life span of approximately 90 days. Actual life span is approximately 120 days.
