| |
lymph | the fluid that the lymphatic system collects and returns to the bloodstream |
| |
Red Blood Cells | Cells in the body that take up oxygen in the lungs and delivers it to cells elsewhere in the body |
| |
lymph node | A small knob of tissue in the lymphatic system that filters lymph |

pacemaker | a group of cells located in the right atrium that sends out signals which make the heart muscle contract and regulate heartbeat rate |
| |
hemoglobin | A iron-containing protein that binds chemically to oxygen molecules and makes up most of red blood cells |
| |
Cell fragments that play an important role in forming blood clots | platelets |
| |
atherosclerosis | a condition in which an artery wall thickens asa result of the buildup of fatty materials |
| |
fibrin | A chemical that is important to blood clotting because it forms a fiber net that traps red blood cells |
