  2. These are the 8 different blood types that a human could have. • What are A+, A-, B+, B-, AB+, AB-, O+, O-?

  3. This is the definition of agglutination. • What is when blood cells clump together do to an immune response?

  4. A person that is A- has these antibodies. Daily Double • What are anti-B and anti-Rh?

  5. A person that is bloodtype B- can receive these bloodtypes in a transfusion. • What are B- and O-?

  6. In order to determine if a person is type A, this is added to the “A” well in the blood typing tray. • What is anti-A serum?

  7. This is the shape a blood drop takes while in flight through the air. • What is a sphere?

  8. This is the percentage of blood lost from the body that would cause death. • What is 40%?

  9. The average human has this many liters of blood in their body. • What is 5-6 liters in males and 4-5 liters in females?

  10. These are the four components of blood. Bonus! • What are plasma, red blood cells, white blood cells and platelets?

  11. This is the property of blood that causes it to contract into a sphere when in flight. • What is surface tension?

  12. This is the definition of a passive blood stain. • What is drops created or formed by the force of gravity acting alone?

  13. This is the definition of a transfer blood stain. • What is a blood stain created when a wet, bloody surface comes in contact with a secondary surface?

  14. These are two examples of types of transfer stains. • What are swipes and wipes?

  15. This is the definition of a projected blood stain. • What is a blood stain created when an exposed blood source is subjected to an action or force, greater than the force of gravity?

  16. These are two examples of projected blood stains. • What are Arterial Spurt / Gush, Cast-Off or Impact Spatter?

  17. These are the names of the three types of impact spatter. • What are high velocity, medium velocity and low velocity?

  18. This is the cause of medium velocity blood spatter. • What is some form of impact from a hand or hand-held object?

  19. This is the cause of high velocity blood spatter. • What is a gun shot?

  20. Medium velocity blood spatter usually falls in this size range. Daily Double! • What is 1-4 mm in diameter?

  21. This is the size of high velocity impact spatter. • What is less than 1 mm in diameter?

  22. When a droplet of blood strikes a surface at an angle perpendicular to that surface, this is the shape of the blood stain. • What is a circle?

  23. As blood stains form at more and more acute angles, this is what happens to the shape of the blood stains. • What is they become more elongated?

  24. This the name for stains that spray off and are disconnected from the main stain. • What are satellites?

  25. These are small parts of a blood stain that are still connected to the main blood stain but stick out from it, giving it the shape of a sun instead of a circle. • What are spines?

  26. These are three characteristics of a blood stain which you can use to determine directionality. • What are satellites, the direction of the tail, the direction of any spines, where on the blood stain did the blood pool?

  27. This is the formula for AOI. • What is sin-1 (W/L)?

  28. This is the formula for determining point of origin. • What is PO= tan (AOI) * distance?

  29. This is the definition of point of convergence. • What is the common point, on a 2 dimensional surface, over which the directionality of several bloodstains can be retraced?

  30. This is the point of origin of a blood stain that has a width of 2 cm and a length of 3 cm and is 20 cm from the point of convergence. Bonus! • What is 22.4 cm?

  31. This is the angle of impact Δ of a blood drop that is 1.1 cm in width and 1.6 cm in length? • What is 46.6 degrees?
