ap·op·to·sis

 (ăp′əp-tō′sĭs, ăp′ə-tō′-)
n.
A natural process of self-destruction by degradative enzymes in certain cells, such as epithelial cells and erythrocytes, that are genetically programmed to have a limited lifespan or are damaged, as by irradiation or toxic drugs. Also called programmed cell death.

apoptosis

(ˌæpəpˈtəʊsɪs)
n
(Biology) biology the programmed death of some of an organism's cells as part of its natural growth and development. Also called: programmed cell death
[C20: from Greek: a falling away, from apo- + ptōsis a falling]
