Forensic Medicine Flashcards

3991253351	Serum	The fluid or liquid portion of the blood that does not clot.	0
3991253352	RBC	Red Blood Cells - Transport oxygen from the lungs via the venous system and return carbon dioxide to the lungs for expiration via the venous system.	1
3991253353	Erythrocytes	Red Blood Cells - Transport oxygen from the lungs via the venous system and return carbon dioxide to the lungs for expiration via the venous system.	2
3991253354	WBUs or Leukocytes	White Blood Cells - assist with defence against foreign substances and infection.	3
3991253355	Platelets	Major components of the clotting mechanism of blood.	4
3991253356	Exsanguination	The process of blood loss, to a degree sufficient to cause death.	5
3991253357	Surface Tension	The force that pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.	6
3991253358	Viscosity	Resistance to change of form or flow.	7
3991253359	Special Gravity	The weight of a substance relative to the weight of an equal volume of water	8
3991253360	Terminal Velocity	The highest velocity attainable by an object as it falls through the air.	9
3991365815	Accompanying Drop	A small blood drop produced as a byproduct of drop formation.	10
3991375220	Altered Bloodstain	A blood stain or pattern with characteristics that indicate a physical change has occurred.	11
3991381564	Angle of Impact	Is the acute angle at which a blood drop spikes a target, relative to the plane of a target.	12
3991390407	Area of Convergence	The area of intersection of two dimensions created by lines drawn through the long axis of individual, most often associated with an impact pattern.	13
3991414889	Area of Origin	The area of three dimensions of a blood source most often associated with an impact pattern.	14
3991429505	Back Spatter Pattern	A bloodstain pattern resulting from blood drops that travel in the opposite direction of the external force applied. Back spatter is often associated with a gunshot entrance wound.	15
3991449028	Blood Clot	A gelatinous mass formed by a complex mechanism involving red cells, fibrinogen, platelets, and other clotting factors.	16
3991459350	Bloodstain	A spot or stain made by blood.	17
3991464807	Bloodstain Pattern	A characteristic grouping or distributions of bloodstains which may indicate the pattern in which the pattern was deposited.	18
3991477173	Bubble Ring	A ring in a bloodstain that results from an air bubble.	19
3991487786	Castoff Pattern	A bloodstain pattern resulting from blood drops released from a bloody object in motion.	20
3991498265	Cessation Castoff Pattern	A bloodstain pattern resulting from blood drops released from a bloody object as it suddenly stops.	21
3991516345	Directionality	The path of travel of a blood drop indicated by the stain's shape.	22
3991523712	Directional Angle	The angle between the long axis of a bloodstain and a reference line on the target.	23
3991530320	Drip Pattern	A bloodstain pattern of a liquid dripping into liquid, where at least one liquid is blood.	24
3991539419	Drip Stain	A bloodstain pattern resulting from the formation and the falling of a drop of blood.	25
3991546540	Drip Tail	A series of bloodstains resulting from blood dripping from a source that is in an horizontal motion.	26
3991711230	Expirated Pattern	A bloodstain pattern resulting from blood being forced out of the nose, mouth, or a wound by air pressure.	27
3991726267	Forward Spatter Pattern	A bloodstain resulting from blood drops that travel in the same direction as the external force applied. Forward spatter is often associated with an exit gunshot wound.	28
3991744313	Flow Pattern	A bloodstain pattern resulting from the movement of a volume of blood on a surface due to gravity and/or a movement of the target.	29
3991755387	Impact Pattern	A bloodstain pattern resulting from an object striking liquid blood.	30
3991767629	Insect Stain	A blood stain produced as a result of insect activity.	31
3991775417	Mist Pattern	A bloodstain pattern resulting from blood reduced to a spray of localized micro-drops, as a result of the force applied, often associated with gunshot injuries.	32
3991795595	Parent Stain	The bloodstain from which wave castoff or satellite bloodstains originate.	33
3991805013	Pool	An accumulation of liquid blood on a surface.	34
3991811036	Void	The absence of blood in an otherwise continuous bloodstain pattern.	35
3991826689	Skeletonize Stain	A bloodstain that has been altered after a period of drying, leaving observable peripheral characteristics of the original stain.	36
3991847742	Transfer Pattern	A bloodstain pattern resulting from contact with a wet bloody surface and another surface.	37
