| S4 | fourth heart sound |
| SA | sinoatrial |
| SBP | systolic blood pressure |
| sinus rhythm | A normal heart rhythm as indicated on an EKG tracing. |
| souffle | A soft blowing sound heard with a stethoscope. |
| sphygmo- | pulse |
| SSS | sick sinus syndrome |
| STH | somatotropic hormone |
| SVT | supraventricular tachycardia |
| systol/o | contraction |

| WPW | Wolff-Parkinson-White syndrome |
| abdominal aorta | The part of the descending aorta passing through the diaphragm into the abdomen. |
| abo blood group | A major blood classification system based on the presence or absence of two antigens, A and B. Type O occurs when neither A nor B is present and AB when both are present. A and B are genetic factors that determine the presence of enzymes for the synthesis |
| acanthocytes | Erythrocytes with spiny projections giving the cell a thorny appearance. |
| accelerated idioventricular rhythm | A type of automatic, not reentrant, ectopic ventricular rhythm with episodes lasting from a few seconds to a minute. The ventricular rate is 50 to 100 beats per minute. |

| angioscope | An endoscope used for viewing the interior of blood vessels. |
| angiotensin | A family of peptides in the blood that causes vasoconstriction and increased blood pressure. |
| ankle brachial index | The ankle-arm index. This is the ratio of the higher of the two ankle systolic blood pressures divided by the higher of the two arm systolic pressures. It is a predictor of peripheral arterial disease. |
| antifibrinolytic | Preventing the breakdown of a blood clot or thrombus. |
| antihypertensive | Drugs used to reduce high blood pressure. |
| arterioles | The smallest divisions of the arteries located between the muscular arteries and the capillaries. |

| blood cell | Any of the cells found in blood. This includes erythrocytes (red cells), leukocytes (white cells) and thrombocytes (platelets). |
| blood clot | A semisolid mass formed by blood coagulation. Thrombus. |
| blood coagulation | The process of the interaction of blood coagulation factors that results in an insoluble fibrin clot. |
| blood count | The number of red or white blood cells in a specified volume of blood. |
| blood group | Classification of blood based upon antigens on the surface of the red cell. Many blood grouping systems have been developed. The ABO system is one of the most important. |
| blood plasma | The liquid part of the blood, free of formed elements and particles. |
| blood transfusion | The administration of whole blood or a blood component into the blood stream. |
| blood vessels | Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins). |
| brachial artery | The continuation of the axillary artery; it branches into the radial and ulnar arteries. |
| capillary fragility | The susceptibility of capillaries, under conditions of increased stress, to rupture. Seen as bleeding under the skin. |
