MICROANATOMY

Detailed explanation-1: -The location of the blood source can be determined by drawing lines from the various blood droplets to the point where they intersect. The area of convergence is the point of origin-the spot where the “blow” occurred.

Detailed explanation-2: -Area of Convergence. If you have a number of bloodstains, the area of convergence can be determined by drawing lines from the leading edge of stains through the long axis. The lines come together in a general area where the blood has emerged, helping to locate the origin of the bloodstains.

Detailed explanation-3: -By examining at least two drops of blood spatter, you will be able to determine where the injured person was located when the injury occurred in two dimensions (line so convergence). You can easily measure the distance from the area of convergence to the drop of blood.

Detailed explanation-4: -The side of the spatter that displays the more prominent spines indicates the direction the blood was traveling. For example, prominent spines on the left indicate the droplet was traveling more or less from right to left. As the angles become more acute, this directionality is more easily identified.

Detailed explanation-5: -Point (Area) of Convergence–The common point (area), on a two dimensional surface, over which the directionality of several blood drops can be retraced. Point (Area) of Origin–The common point (area) in a three dimensional space to which the trajectories of several blood drops can be retraced.
