Blood Type
A, B, AB, and O.
What are the four blood types of humans?
indicates the presences of a specific protein, discovered with a rhesus monkey. determines if blood is negative or positive
What is RH factor?
Evidence that liquid blood has come into contact with a surface.
What is a bloodstain?
A bloodstain pattern that creates spatter
What is a impact?
The acute angle formed between the direction of a blood drop and the plane of the surface it strikes.
What is the angle of impact?
A person of type O is also called a universal ____________.
What is donor?
A= clots +
B= not clots -
Rh= clots +
What is A+ ?
type of blood stain created by gravity;drops or pools
What is passive
Bloodstain drop(s) created or formed by the force of gravity acting alone.
What is a passive drop, or bleeding?
What happens to blood drops the faster you move?
What is length grows?
A person with this type of blood may receive blood from anyone!
What is type AB?
A=not clot -
B=not clot-
Rh= clot+
What is O+?
As height is increased, the size of the blood droplet ___________.
What is increase?
A bloodstain pattern caused by an object coming into contact with a previous bloodstain and leaving wipes behind.
What is transfer?
The slower the speed of blood spatter, the SMALLER the drops on a surface will be. T or F
Fase
Blood that contains B antigens
What is A blood type?
A liquid that separates from clotted blood.
What is serum?
The size of a blood droplet would be __________________ on glass than it would be on carpeting. (smaller/larger)
What is larger?
results when an object is an arc flings blood onto nearby surfaces.
What is cast off?
What is the formula for solving for the angle of impact of blood spatter?
sin-1(length/width)
A blood type that contains both A and B antigens
What is O blood type?
Proteins in the blood or secretory fluids that tag, destroy, or neutralize bacteria, viruses, or other harmful toxins, producing an immune response.
What are antibodies?
what does BPA stand for?
What is Bloodstain Pattern Analysis
type of spatter that results when air mixes with blood and then is expelled through the nose mouth or lungs.
What is experiated?
The jagged pattern that is created when blood drops onto a surface. The higher the drop, the more of this pattern is produced.
What is spining?
