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.
Taste buds and olfactory receptor cells are the fastest growing and most rapidly regenerating cells in the body. Taste buds regenerate completely in a 24 hour period. The entire bud is replaced by new cells on a daily basis.lfactory epithelial cells are also among the fastest growing and regenerating cells in the body. Olfactory epithelial cells, unlike taste bud cells, regenerate in a variety of time frames, from every 24 hours to days and weeks.
