The typical life span of a healthy red blood cell is approximately 120 days.

Hemoglobin itself does not have a lifespan, as it is a protein within red blood cells (RBCs). The average lifespan of a red blood cell, which contains hemoglobin, is about 120 days. After this period, red blood cells are typically removed from circulation by the spleen and liver, and their hemoglobin is broken down and recycled by the body.
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.
Repeated sickling and unsickling of red blood cells, as seen in conditions like sickle cell disease, leads to increased cell damage and a higher rate of hemolysis. This mechanical stress shortens the lifespan of the affected red blood cells, which typically live around 120 days under normal conditions. In sickle cell disease, the average lifespan can drop to as low as 10 to 20 days. As a result, the body struggles to produce enough healthy red blood cells to maintain adequate oxygen transport.
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.
