1

Hematology

Study of blood

2

Hematologist

Physician who studies blood

3

Hemorrhage

Rapid flow of blood

Hemophilia

Hereditary blood disease in which the blood clotting time is prolonged. You could bleed to death.

5

Anemia

A reduction in the number of red blood cells or the amount of hemoglobin in the blood.

6

Polycythemia Vera

Production of too many red blood cells by the bone marrow. Blood becomes too thick.

7

Sickle cell anemia

A genetic disorder in which the erythrocytes take on an abnormal curved or "sickle" shape.

8

Leukemia

Cancer of the white blood cell

9

Erythrocyte sedimentation rate

Blood test to determine the rate at which mature red blood cells settle out of the blood

10

Hematocrit (HCT, Hct, crit)

Blood test to measure the volume of the red blood cells within the total volume of blood.

11

Prothrombin time

A measure of the bloods coagulation abilities

12

Phlebotomy

Incision into a vein in order to remove blood

13

Autologous transfusion (auto-self)

Procedure for collecting and storing a patients (OWN BLOOD) it can then be used to replace blood lost during a surgical procedure.

Replacement of blood by transfusion of blood received (FROM ANOTHER PERSON)

15

Lymphatic system

1. Lymphatic vessels

2. Lymph nodes

3. Spleen

4. Thymus gland

5. Tonsils

16

Lymph nodes or glands

House lymphocytes and anti-bodies that work to remove pathogens and cell debris

Passive acquired immunity

Results when a person receives protective substances produced by another human or animal

E.g. Mother passing anti-bodies to baby through milk

E.g. Receiving anti-venom after snake bite

20

Active acquired immunity

Such as immunizations or vaccines

21

Cellular immunity involves the production of T cells and NATURAL KILLER (NK) cells. The defense cells are CYTOTOXIC, meaning that they physically attack and destroy pathogenic cells.

Natural Killer Cells (NK)

Cytotoxic

22

Erythroblastosis Fetalis

Condition where anti-bodies in Mothers blood enter the fetus' blood & cause anemia, jaundice, edema & enlargement of the spleen & liver.
