What is the life span of Red Blood Cells?

Last Updated:

What is the life span of Red Blood Cells? Questions may also test blood components, vitamins, glands, sense organs, communicable diseases, and deficiency disorders. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to 120 days.

A30 days
B60 days
C120 days
D180 days
Correct Answer: 120 daysYour Answer: C

Explanation

30 days is incorrect because it refers to a different organ, substance, process, or medical association. 60 days is also incorrect; it may be biologically important, but its principal role or defining feature is not the one being tested here. 180 days is incorrect because its function, source, target, or disease relationship does not match the question. Decide whether it concerns anatomy, physiology, blood, hormones, vitamins, immunity, pathogens, or disease. Therefore option C, 120 days, is factually consistent with the stem, the marked correct index, and the explanation. Red blood cells (RBCs) have a lifespan of about 120 days.
