Detailed explanation-1: -Lividity is the bluish-purple discoloration of skin after death. It is a sign of livor mortis and occurs when blood pools at the lowest point of the body due to gravity and loss of blood circulation.

Detailed explanation-2: -Livor mortis, also known as lividity or hypostasis, is the gravitational pooling of blood to lower dependant areas resulting in a red/purple coloration. Although livor mortis is commonly seen between 2 and 4 h postmortem, its onset may begin in the ‘early’ period, as little as 30 min postmortem.

Detailed explanation-3: -Livor mortis or lividity is the gravitational pooling of blood in the dependent parts of the body, both externally in the skin capillaries and venules but also in the internal organs.

Detailed explanation-4: -It is a settling of the blood in the lower, or dependent, portion of the body postmortem, causing a purplish red discoloration of the skin. When the heart stops functioning and is no longer agitating the blood, heavy red blood cells sink through the serum by action of gravity.

Detailed explanation-5: -Postmortem hypostasis (livor mortis or lividity) is classically defined as the intravascular pooling of blood in gravitationally dependent parts of the body after death. However, intense lividity can be associated with small hemorrhages in the skin, so-called postmortem hypostatic hemorrhages (Tardieu spots).
