How many trips around the human body do red blood cells make before they die?

Respuesta :

Answer:

One minute

Explanation:

The cells develop in the bone marrow and circulate for about 100–120 days in the body before their components are recycled by macrophages. Each circulation takes about 60 seconds (one minute). Approximately 84% of the cells in the human body are red blood cells.
