2. The Cardiovascular System
The Blood Vessels
The Cardiovascular System

3. Arteries Carry blood away from the heart Structure: Function:
Tunica interna – endothelial cells
Tunica media – smooth muscle (blood pressure)
Tunica externa – elastic tissue
Function:
Distribution of nutrients, gases, etc, with movement of blood under high pressure
Assist in maintaining arterial blood pressure
Arteries

6. Veins Carry blood toward the heart Structure: Function:
Tunica interna – valves prevent movement of blood
Tunica media – smooth muscle (thinner than artery)
Tunica externa – heavy layer
Function:
Collect blood for return to the heart
Low pressure vessels
Veins

8. Capillaries Carry blood from the arterioles to venules Structure:
Microscopic vessels
Only layer is tunica interna
Capillaries

11. Combining Forms Angi/o – vessel Arteri/o – artery
Phleb/o, ven/o – vein
Ather/o – yellow, fatty plaque
Isch/o – deficiency, blockage
Therm/o – heat
Combining Forms

12. Diseases/Disorders (NBFWP)
Coronary artery disease – reduces flow of blood through coronary arteries through the myocardium resulting in heart tissue necrosis (death)
Deep vein thrombosis – thrombus in a deep vein; clot can break off causing pulmonary embolism
Varicose veins – distended or torturous veins found in lower extremeties
Diseases/Disorders (NBFWP)

15. Surgical Terms (NBFWP)
Coronary stent – device implanted in coronary artery used to prevent closure of the artery
Surgical Terms (NBFWP)

16. Diagnostic Terms (NBFWP)
Dopplar ultrasound – uses sound for detection of blood flow within the vessels
Blood pressure – pressure exerted by the blood against the blood pressure walls
Percussion – tapping of a body surface with the fingers to determine the density beneath
Pulse – number of times per minute the heartbeat is felt on the arterial wall
Sphygmomanometer – device used to measure blood pressure
Stethoscope – instrument used to hear internal body sounds
Diagnostic Terms (NBFWP)

17. Complementary Terms (NBFWP)
Hypertension – blood pressure above normal (>140/90)
Hypotension – blood pressure below normal (<90/60)
Lumen – space within a tubular part
Occlude – close tightly, block
Vasoconstrictor – agent that narrows the blood vessels
Vasodilator – agent that enlarges the blood vessels
Venipuncture – puncture of vein to remove blood, instill medication or start intravenous infusion
Complementary Terms (NBFWP)
