The Blood Type Matching game (opens window) is secondary and optional. The object of the game is to score as many points as possible by matching the appropriate blood type of a donor to the blood type of a recipient. During each round, a total of 10 recipients will walk onto the screen. You then click on the donor you think is a match — there’s no guarantee that a match exists every time. Each round has a set amount of matches you must make to proceed, and time gets shorter with each progressive round you face.
1. Tell me which antigens (A, B and/or Rh) would be found on the red blood cell and which antibodies (A, B, and/or Rh) would be found in the plasma of the following individuals. (Note : antibodies are called Anti-A antibody and not A antibody).
| Blood Type | Agglutinogens or antigens | Agglutinins or antibodies in plasma | Can donate blood to type | Can receive blood from type |
| Type A+ | A, Rh | A, AB | ||
| Type B- | Anti- A | B, O | ||
| Type AB+ | None | AB | ||
| Type O-
(exposed to Rh+ blood) |
None | O |
2. Why is type O considered the universal donor? (It can give to all blood types is NOT acceptable, explain what its blood antigen/ antibody make up has to do with this ability).
3. Why is type AB the universal recipient? (It can receive from all blood types is NOT acceptable, explain what its blood antigen/ antibody make up has to do with this ability)
4. If patient 2, from the chart above (B-), was given B+ blood, what would happen in regards to her/his plasma antibodies?

The heart has its own system in place to create nerve impulses and does not actually require the brain to make it beat. This electrical system is called the cardiac conduction system. It is made up of specialized tissues and cells embedded in the heart that send impulses directly to the atria and ventricles, causing them to contract. In the normal cardiac cycle, the left and right atria contract together first followed by the contraction of the ventricles together.
a. The cardiac conduction system is complex, but there are five crucial parts. Name the parts of the conduction system beginning at the sinoatrial (SA) node.
1. ____
2. ____
3. ____
4. ____
5. ____
An electrocardiogram is a measurement of the electrical activity and impulses created by the heart. It is most often referred to as an EKG or ECG. Electrodes are placed on the chest and each electrical impulse is translated into a wave pattern on a grid. The grid allows for the calculation of the duration and amplitude of each impulse, as well as whether the impulses are abnormal or irregular. Flat lines on the grid represent no electrical activity, upward spikes represent electrical activity or depolarization, and downward spikes represent repolarization.
1.
2. P wave _____
3. QRS Complex _____
4. T wave _____
5. PR Interval _____
6. QT interval _____
a. Time between the depolarization of the atria and ventricles
b. Depolarization and contraction of the right and left atria
c. Repolarization and relaxation of the ventricles
d. Time for the ventricles to contract and relax
e. Depolarization and contraction of the right and left ventricles
1. T wave _____
2. QT Interval _____
3. P wave _____
4. PR Interval _____
5. QRS Complex _____
