Bloodstain pattern analysis || Questions with complete solutions

What elements may be useful for interpreting and reconstructing the events that produced the bleeding correct answers Location, distribution, and appearance of bloodstains and spatters What can bloodstain pattern interpretation uncover correct answers -the direction from which blood originated - the angle at which a blood droplet struck a surface - the location or position of a victim at the time a bloody wound was inflicted - the movement of a bleeding individual at the crime scene - the approximate number of blows that struck a bleeding victim - the approximate location of an individual delivering blows that produced a bloodstain pattern What must be considered when determining the direction, dropping distance, and angle of impact of a bloodstain correct answers Surface texture, stain's shape, size, and location The harder and less porous the surface correct answers The less splatter results The direction of travel of blood striking an object may be discerned because the pointed end of a blood stain always faces ____________ correct answers It's direction of travel Once blood leaves the body it behaves as fluid and all physical laws apply : correct answers Gravity - acts on blood as soon as it exits the body - given the right circumstances blood can act according to ballistic theory Viscosity - amount of internal friction in the fluid - describes the resistance of a liquid to flow Surface tension - force that maintains the shape of a drop of liquid, such as blood. - when two fluids are in contact with each other ( blood and air) there are forces attracting all molecules to each other The impact angle of blood on a flat surface can be determined by correct answers Measuring the degree of circular distortion On a flat surface at right angles the blood drop is ______, as the angle decreases the stain becomes ___________ correct answers Circular Elongated
