Verified step by step guidance

Understand the life cycle of erythrocytes: Erythrocytes, or red blood cells, are produced in the bone marrow, circulate in the bloodstream, and are eventually broken down in the liver and spleen.

Recognize the lifespan of erythrocytes: They typically have a lifespan of about 120 days, after which they are removed from circulation and broken down.

Identify the key characteristic of erythrocytes: Unlike many other cells, erythrocytes lack a nucleus and organelles, which means they cannot repair themselves when damaged.

Evaluate the statements provided: Compare each statement against the known characteristics of erythrocytes to determine which one is not true.

Conclude which statement is false: Based on the understanding that erythrocytes cannot repair themselves due to the absence of a nucleus and organelles, identify this as the incorrect statement.
