blood transfusion
|
transference of blood from 1 person to another
|
|
marker molecules
|
determine the blood type and type of blood that can be safely recieved in a transfusion. Red blood cells with foreign marker molecules are affected by proteins found in the plasma that causes the cells with "foreign" markers to clump together
|
|
safe transfusions
|
blood that does not contain red blood cells with marker molecules that your body sees as foreign.
|
|
cross-matching
|
when your blood type is checked against blood that was donated to ensure that it is compatible before a transfusion.
|
|

|
Blood types A and O
|
|
Blood Type B can safely recieve
|

|
Blood types A, B, AB, and O
|
|
Blood Type O can safely recieve
|
Blood type O
|
|
lymph
|
liquid that leaks out across the capillaries. It is called lympy when it enters the lympathic system. made up of water and dissolved materials (like glucose), this fluid carries the materials that cells and tissues need.
|
|
lymph nodes
|
small knobs of tissue that act as filters for the lymph
|
|
When do lympy nodes enlarge?
|
When the body is fighting an infections
|
|
atherosclerosis

the thickening of the artery wall due to the build up of fatty materials (like cholesterol). Especially bad when it occurs in the coronary arteries
|
|
heart attack

|
|
3 ways to keep the cardiovascular system healthy
