Blood Vocab
| Term | Definition |
|---|---|
| Arteries | Blood Vessels that carry blood away from the heart |
| Veins | Blood Vessels that carry blood toward the heart- Many veins have one-way valves that keep blood moving toward the heart |
| Capillaries | microscopic blood vessels that connect arteries to veins. They are where the blood does most of its work |
| Cardio | a prefix that refers to the heart (as in cardiologist) |
| Pulmo | a prefix that refers to the lungs (as in pulmonary) |
| Hemo | a prefix that refers to blood (as in hemoglobin) |
| Red Cells Responsibility | deliver oxygen to cells using the hemoglobin protein |
| White Cells Responsibility | fight infections |
| Plasma | The liquid part of the blood, mostly water |
| Platelets | Cells that form clots to stop bleeding |
| A blood cell with only A proteins is type... | A blood |
| A blood cell with only B proteins is type... | B blood |
| A blood cell with both a & b proteins is type.. | AB blood |
| A blood cell with neither A nor B proteins is type... | O blood |
| A blood cell with RH proteins attached has... | An RH factor of positive |
| A blood cell with no RH proteins attached has... | An RH factor of negative |
| Transfusion | Transferring blood from one person to another. For transfusions to be safe, the donated blood cannot have an A, B, or Rh protein that the recipient's blood does not possess. |
| Antibodies | Proteins produced by the immune system to fight infection or foreign substances in the body. The body will produce antibodies that attack donated red cells that have an A, B, or Rh protein that the body does not possess itself. |
| Universal Donor | a person with blood type O- which can be safely donated to anyone |
| Universal Recipient | a person with type AB+ blood who can safely receive any blood type |
| Blood type testing | A, B and Rh antibodies are added separately to 3 drops of blood. If the blood reacts to an antibody (clots) it shows that the A, B or Rh blood protein is present in the blood. By knowing which of the proteins are in the blood you can find the blood type. |
| Inheritance of blood type | Blood type is inherited and remains the same for life. |
| Genes | The basic units of inheritance. Everyone possesses two copies of each gene, one inherited from each of their parents. |
| Dominant | The ”stronger” gene of a pair. This gene usually will determine what trait the person actually exhibits |
| Recessive | The ”weaker” gene of a pair. A person will usually exhibit this trait only if they inherit 2 copies of this gene |
| If a person inherits the genes A/A... | Their blood type is A |
| If a person inherits the genes A/O... | Their blood type is A |
| If a person inherits the genes A/B... | Their blood type is AB |
| If a person inherits the genes B/B... | Their blood type is B |
| If a person inherits the genes B/O... | Their blood type is B |
| If a person inherits the genes O/O... | Their blood type is O |
| If a person inherits the genes +/- or +/+... | They have an Rh factor of positive |
| If a person inherits the genes -/-... | They have an Rh factor of negative |
