about death include aging, predation, malnutrition, disease, suicide, homicide, starvation, dehydration, and accidents or major
trauma leading to terminal injury. In most cases, bodies of living organisms begin to decompose shortly after death.
Death – particularly the death of humans – has commonly been considered a tragic or unpleasant occasion, thanks to the love for
the being that has died and therefore the termination of social and familial bonds with the deceased. Other concerns include fear of death,
necrophobia, anxiety, sorrow, grief, emotional pain, depression, sympathy, compassion, solitude, or saudade. Many cultures and
religions have the thought of an afterlife, and also hold the thought of reward or judgement and punishment for past sin.
Senescence
Senescence refers to a scenario when a living being is in a position to survive all calamities, but eventually dies thanks to causes concerning
old age. Animal and plant cells normally reproduce and performance during the entire period of natural existence, but the aging
process derives from deterioration of cellular activity and ruination of normal functioning. Aptitude of cells for gradual
deterioration and mortality means cells are naturally sentenced to stable and long-term loss of living capacities, even despite
continuing metabolic reactions and viability. within the uk , for instance , nine out of ten of all the deaths that occur on
a day to day relates to senescence, while round the world it accounts for two-thirds of 150,000 deaths that happen daily .
Almost all animals who survive external hazards to their biological functioning eventually die from biological aging, known in
life sciences as "senescence". Some organisms experience negligible senescence, even exhibiting biological immortality. These
include the jellyfish Turritopsis dohrnii, the hydra, and therefore the planarian. Unnatural causes of death include suicide and predation.
From all causes, roughly 150,000 people die round the world every day . Of these, two thirds die directly or indirectly thanks to
senescence, but in industrialized countries – like the us , the uk , and Germany – the speed approaches
90% . Where within the process a line is drawn between life and death depends on factors beyond the presence or absence of
vital signs. generally , clinical death is neither necessary nor sufficient for a determination of legal death. A patient with working
heart and lungs determined to be dead are often pronounced legally dead without clinical death occurring. As scientific
knowledge and medicine advance, formulating a particular medical definition of death becomes harder .
Diagnosis
Signs
Signs of death or strong indications that a warm-blooded animal is not any longer alive are:
Respiratory arrest
Cardiac arrest
Brain death
The stages that follow after death are:
, paleness which happens within the 15–120 minutes after death
, the reduction in blood heat following death. this is often generally a gentle decline until matching ambient temperature
, the limbs of the corpse become stiff and difficult to maneuver or manipulate
, a settling of the blood within the lower portion of the body
Putrefaction, the start signs of decomposition
Decomposition, the reduction into simpler sorts of matter, amid a robust , unpleasant odor.
Skeletonization, the top of decomposition, where all soft tissues have decomposed, leaving only the skeleton.
Fossilization, the natural preservation of the skeletal remains formed over a really long period
Problems of definition
The concept of death may be a key to human understanding of the phenomenon. There are many scientific approaches and various
interpretations of the concept. Additionally, the arrival of life-sustaining therapy and therefore the numerous criteria for outlining death
from both a medical and legal standpoint, have made it difficult to make one unifying definition.
One of the challenges in defining death is in distinguishing it from life. As some extent in time, death would appear to ask the
moment at which life ends. Determining when death has occurred is difficult, as cessation of life functions is usually not
simultaneous across organ systems. Such determination therefore requires drawing precise conceptual boundaries between life
and death. this is often difficult, thanks to there being little consensus on the way to define life.
It is possible to define life in terms of consciousness. When consciousness ceases, a living organism are often said to possess died.
One of the issues during this approach is that there are many organisms which are alive but probably not conscious . Another problem
is in defining consciousness, which has many various definitions given by modern scientists, psychologists and philosophers.
Additionally, many spiritual traditions, including Abrahamic and Dharmic traditions, hold that death doesn't entail the top of
consciousness. In certain cultures, death is more of a process than one event. It implies a slow shift from one spiritual state to
another.
