100-120 days (4 months)
120 days.
The typical life span of a healthy red blood cell is approximately 120 days.
120 days
the average size of a red blood cell is about 7.2 micrometers in diameter.
The nuceli is ejected after the cell is formed. This affects not the life span, but the ability to make energy. The life span of a red blood cell is 120 days.
Red blood cells "hang out" in the bloodstream, where they transport oxygen from the lungs to all tissues in the body and remove carbon dioxide for exhalation. The average lifespan of a red blood cell is around 120 days, after which they are broken down and recycled by the body's immune system.
Red blood cells do not have nuclei, making it difficult to directly determine their age. However, in some cases, laboratory techniques like measuring the levels of certain biomarkers or using isotopic labeling can provide insights into the average lifespan of red blood cells in circulation.
Round about 21 days is the average span of a blood cell
A red blood cell, also known as an erythrocyte, has a lifespan of about 120 days in the human body. After this period, they are removed by the spleen and liver, and new ones are produced by the bone marrow to replace them.
The average red blood cell lasts about 120 days.
The size of a white blood cell is on average about 700 times smaller than a red blood cell. Source: http://library.thinkquest.org/25896/sub_blood/wbc.htm
