20 BOY SCOUTS OF AMERICA Campmasters With the exception of summer camp programs, our camps are served by campmasters â volunteers who staff the office, provide weekend programs, serve our campers and ensure the safety and well-being of our visitors.
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.
So we can calculate the amount produced per minute to resupply all RBCs every 120 days. 5 trillion divided by 120 days, divided by 24 hours, divided by 60 minutes is 28,935,185 RBCs per minute. Keep in mind, this depends on how much you weigh, your gender, and how well your body utilizes oxygen.
