A patient has AB- blood. What types of blood can they receive?
A-, B-, AB-, and O-
(They do not have antibodies in their blood)
The scientific name for a red blood cell.

Which layer of a hair shaft has pigment-containing granules, which are responsible for hair color?
Which type of blood is considered the universal receiver?
What is TYPE AB BLOOD?
A patient has B+ blood. What types of blood they can receive in a transfusion?
Types B+, B-, O+, O-
The scientific name for a white blood cell.
What is a LEUKOCYTE?
Name the ridge pattern in the image (image in Google Slides).
What is a WHORL?
What is the protein that makes up hair, skin, and nails?

Which type of blood is considered the universal donor?
A patient has Type A+ blood. In a transfusion, what type of blood can this patient receive.
Types A+, A-, O+, and O-
The scientific name for a platelet.
What is a THROMBOCYTE?
Look at the texts on the phone. What information did you learn from the digital evidence?
-Brad and someone else were involved in fraud at a company
-They are destroying evidence
The diameter of the innermost layer of the hair shaft is useful in identification. Name the innermost layer.
What is the MEDULLA.
Using the image, name ALL blood samples that were Type A in the Anna Garcia Case.
-Both scene samples
-Anna Garcia
-Eric Piedmont
-Dominique Hall
A patient has type O+ blood. What type of blood can they receive in a transfusion?

Describe why agglutination occurs when you add B antibodies to type AB blood.
The B antibodies attach to the B antigens on the surface of the red blood cells. This causes clumping, or agglutination in the blood.
A patient has AB+ Blood. Why is this the best type of blood to have if someone is in need of a red blood cell transfusion?
This is the best type of blood to have if you need a transfusion because there are no antigens in the plasma so they can receive ALL blood types. Since this patient is + for the Rh factor, they can receive + and - blood.
The name of the surface proteins found on red blood cells.
