In humans, what is the typical lifespan of a mature red blood cell (erythrocyte) in circulation under normal physiological conditions?
A
About 120 days
B
About 7 days
C
About 365 days
D
About 30 days
Verified step by step guidance1
Understand that mature red blood cells (erythrocytes) are specialized cells responsible for transporting oxygen throughout the body using hemoglobin.
Recall that red blood cells lack nuclei and most organelles, which limits their ability to repair themselves and contributes to their finite lifespan.
Recognize that under normal physiological conditions, red blood cells circulate in the bloodstream for a specific period before being removed by the spleen and liver.
Identify from biological studies and textbooks that the typical lifespan of a mature human red blood cell is approximately 120 days.
Conclude that among the given options, 'About 120 days' is the correct typical lifespan of a mature red blood cell in circulation.
