Biological death is a term used to describe the permanent cessation of vital bodily functions. It is an irreversible condition, marked by the absence of heartbeat and breathing. Synonyms for biological death include clinical death, somatic death, and irreversible coma. While the specifics of each term may vary slightly, they all describe the same condition - the end of biological life. It is important to note that although the heart and lungs may stop functioning, brain activity can persist for a short period. However, once irreversible brain damage has occurred, the condition is known as brain death. Whether referred to as biological death, clinical death, or somatic death, the end result is the same - the end of life.
