Transportation - of gases, nutrients, waste products, and hormones

Regulation - of pH, body temperature, and fluid volume; contains buffers, heat, and sodium/ proteins respectively

Protection - against foreign substances; contains antibodies for immunity
- against blood loss; contains platelets and clotting factors

How do red blood cells age?

Red cells have an average life span of about 120 days after which they are cleared by- phagocytosis by reticuloendothelial macrophages due to accumulated changes during their life span. Approximately 5 million erythrocytes (the average number per μl) are removed from the circulation every second.

What happens to a red blood cell as it matures quizlet?

How does a red blood cell change as it matures? they lose their nuclei as they mature to allow more space for hemoglobin. This also prevents them from being able to synthesize proteins or divide.

What is the term for a mature red blood cell?

Mature red blood cells (RBCs, also called erythrocytes) are cells separated from blood and named for its red color. Human RBCs are developed in adult bone marrow through erythropoiesis. During erythroid maturation, RBCs lose nucleus and most organelles to accommodate maximum space for hemoglobin.

How long does a red blood cell typically exist in the bloodstream quizlet?

Lifespan of a RBC is 120 days. During those 120 days, the red blood cell travels around in the bloodstream, carrying oxygen. As it passes into the small capillaries, it folds to fit through those small vessels.
