Question
Answer

🗑
Aorta   Is the main part of arterial system, begins in the left ventricle of the heart.  
🗑
Coronary Arteries   Supplies the heart with blood  
🗑
Arterioles   Thinner branches, carry blood to capillaries.  
🗑
Capillaries   Blood vessels that connect arteries and veins to each other. Smallest vesses in the body  
🗑
Blood flow   slower in capillaries to allow time for exchange of oxygen, nutrients, and waste products between surrounding cells and fluids  
🗑
Veins   Responsible for carrying waste-filled blood back to heart  
🗑
Valves in veins   Allow for one-way blood flow toward heart  
🗑
Venules   small veins that join to form larger veins  
🗑
Pulse   Expansion and contraction of an artery caused by the pressure applied against the walls of the vessels  
🗑
Systolic pressure   The upper number of a blood pressure reading  
🗑
Diastolic Pressure   The lower nuber of a blood pressure reading  
🗑
Blood   Composed of 55% liquid plasma and 45% formed elements.  
🗑
Formed elements   Red blood cells, white blood cells, and platelets  
🗑
Plasma   Liquid part of blood, contains nutrients wastes and hormones. 91% water, 9% proteins  
🗑
Fibrinogen and Prothrombin   Clotting proteins to help blood clot and control bleeding.  
🗑
Erythrocytes or RBC's   contains hemoglobin, or iron containing portion of erythrocyte, live 120 days  
🗑
Hemoglobin   transports oxygen from the lungs to the tissues of the body  
🗑
Leukocytes or WBC's   Protect body against infection, five types of leukocytes.  
🗑
Neutrophils   Majority of WBC's, fight infection by phagocytosis  
🗑
Basophils   Promote inflammatory response, elevated basophil count may indicate an allergic condition  
🗑
Eosinophils   Formed in red bone marrow, increase in response to allergic condition  
🗑
Lymphocytes   Formed in red bone marrow, lymph nodes, and spleen, protect body against disease  
🗑
Monocytes   Formed in red bone marrow, lymph nodes and spleen, help fight disease.  
🗑
Thrombocytes (Platelets)   smallest formed elements in the blood; when blood vessel is damaged platelets become sticky and clump together.  
🗑
Rh positive   You have the Rh antigen  
🗑
Rh Negative   You do not have Rh antigen  
🗑
Aneurysm   Weak spot in the wall of an artery, causes it to balloon out and sometimes rupture.  
🗑

🗑
Varicose Veins   Abnormally swollen veins usually occuring in the legs  
🗑
Thrombus   Blood clot attached to inside wall of vein or artery  
🗑
Embolus   blood, air, fat or other substance in the bloodstream.  
🗑
Embloism   the blockage of the blood vessel by the embolus  
🗑
Low density lipoprotein (LDL)   Bad kind, contribute to plaque buildup in the arteries causing a blockage for blood flow  
🗑
High Density Lipoprotein (HDL)   Good kind, Carries uneeded cholesterol back to the liver for processing; does not contribute to plaque build-up in the arteries  
🗑
Triglycerides   Combination of fatty acids and glycerol found in the blood  
🗑
Leukemia   Progressive increase in the number of abnormal leukocytes; malignant disorder  
🗑
Anemia   Lower than normal number of red blood cells  
🗑
Irond Deficiency anemia   Develops if not enough iron is available to the bone marrow to make hemoglobin.  
🗑
Sickle Cell anemia   Genetic disorder that causes abnormal hemoglobin  
🗑
Pulse Oximeter   External monitor that is applied to the finger to measure oxygen saturated with oxygen. Normal is above 96% or 90%  
🗑
Blood gases   Measuremetn of other gases in blood (in addition to oxygen)  
🗑
P   Pulse  
🗑
BP   Blood Pressure  
🗑
RBC   Red Blood Cells  
🗑
WBC   White BLood Cells  
🗑
LDL   Low density Lipoprotein  
🗑
HDL   High density lipoprotein  
🗑
ABG   Arterial blood gas  
🗑
tPA   Tissue plaminogen activator  
🗑
