In humans, mature red blood cells are flexible and oval biconcave disks. They lack a cell nucleus and most organelles, in order to accommodate maximum space for hemoglobin. Approximately 2.4 million new erythrocytes are produced per second in human adults. The cells develop in the bone marrow and circulate for about 100â120 days in the body before their components are recycled by macrophages. Each circulation takes about 20 seconds. Approximately a quarter of the cells in the human body are red blood cells.
The human body is an incredible machine. Part of what makes it so impressive (apart from the concept of conciousness and self awareness) is its ability to regenerate itself. Your outer layer of skin, the epidermis (apart from the thicker dermis beneath), replaces itself every 35 days.You are given a new liver every six weeks (a human liver can regenerate itself completely even if as little as 25% remains of it).Your stomach lining replaces itself every 4 days, and the stomach cells that come into contact with digesting food are replaced every 5 minutes.our diet has a major impact on how successfully your body is at these regenerations, so for a list of the best things to eat to help your body replace itself, visit this site. Someone once told me that white wine works the best, so Iâm trying that tonight. Doinâ it for my body.
