Cath Lab Exam 1
•High-pressure jsystem.
Vascular jsystem
• Thicker jvessel jwalls/smaller jlumen.
jreview j- jArteries
• Blood jflows jfrom jlarge jvessels jto jsmall.
• Carries joxygen jrich jblood jto jthe jbody jexcept jfor jthe
jpulmonary jsystem. jPulmonary jarteries jcarry joxygen
jpoor jblood jto jthe jlungs jfrom jthe jheart.
2. •Low-pressure jsystem.
Vascular jSystem
• Thinner jvessel jwalls/larger jlumen.
jReview j-Veins
• Blood jflows jfrom jsmall jvessels jto jlarge-Barring jthe
jportal jsystem.
• Carries joxygen-poor jblood jfrom jthe jbody jexcept jin
jthe jpulmonary jsystem. jPulmonary jvein jcarries joxy-
jgen-rich jblood jfrom jthe jlungs jto jthe jheart.

5. - jMiddle jlayer
Tunica jMedia
• Muscular jportion jof jthe jvessel.
• Controls jblood jpressure j(BP) jby:
Vasodilation
-Reduces jBP
• Muscle jrelaxation.
• Widens jthe jvessel jlumen
jVasoconstriction
, Cath Lab Exam 1
-Increases jBP
• Smooth jmuscle jcontraction
• Reduces jthe jdiameter jof jthe jlumen
