100

The droplet from which a satellite spatter originates

Parent Drop

100

a chemical usually referred to as the Kastle-Meyer test and produces a _____________ color when it reacts with hemoglobin.

Pink

100

There are three alleles for genes for blood type. Name them.

A, B and O

100

How many liters of blood are in the adult human body?

5

100

The yellowish liquid portion of blood that contains electrolytes, nutrients and vitamins, hormones, clotting factors and proteins such as antibodies to fight infections.

Plasma

200

The pointed edges of a stain that radiate out from the spatter.

Spines

200

This chemical is used to locate traces of blood, even if it has been cleaned or removed. Investigators spray a solution throughout the area under investigation and look for reactions with the iron present in blood, which causes a blue luminescence.

Luminol

200

People with type O blood are universal ___________.

Donors

200

Your blood type is established before you are born by specific ___________ inherited from your parents.

Genes

200

They are a part of our immune system and destroy infectious agents called pathogens.

White blood cells

300

The angle at which a blood droplet strikes a surface

Angle of impact

300

This chemical is also capable of detecting latent or old blood. However, a special light and goggles are used to detect any illuminated areas, which appear greenish-white if blood is present. It may also react to many of the same things as luminol (copper and bleach).

Fluorescein

300

There are 6 possible combinations of blood types. Name them.

AA, AO, BB, BO, OO, AB

300

Genes determine your blood type by causing proteins called agglutinogens to exist on the surface of all of your RBC's.

agglutinogens

300

The clotting factors that are carried in the plasma; they clot together in a process called coagulation to seal a wound and prevent the loss of blood.

Platelets

400

Patterns that occur when a force is applied to the source of the blood–Includes low, medium, or high impact spatters, cast-off, arterial spurting, expiratory blood blown out of the nose, mouth, or wound.

Projected blood stains

400

One type of chemical process that is used for blood enhancement to make the blood evidence more visible so it can be photographed and analyzed.

LCV or Leuco Crystal Violet

400

People with type AB blood are universal ______________.

recipients

400

There are about how many red blood cells in two to three drops of blood.

1 billion

400

Another name for erythrocyte.

Red blood cell (RBC)

500

Small drops of blood that break off from the parent spatter when the blood droplet hits a surface.

Satellite Spatters

500

Also called presumptive tests. These tests are used to detect blood at crime scenes based upon the properties of hemoglobin in the blood. Further tests at the crime lab can determine if it is human blood or not. The Kastle-Meyer tests uses phenolphthalein and hydrogen peroxide, while HemaStix is a paper strip coated with TMB.

Blood Reagent Tests

500

A protein that is found in the blood of humans and Rhesus monkeys

Rh factor

500

The most abundant cells in our blood. They are produced in the bone marrow and contain a protein called hemoglobin that carries oxygen to our cells.

Red blood cells

500

Another name for Thrombocyte

Platelet
