Vascular intro Flashcards
Heparin
Systemic anticoagulant
Inhibit natural clotting mechanism to prevent clot formation
Protamine
Anticoagulant
Reversal agent for heparin
Papavarine
Smooth muscle relaxant Prevent venospasm (or vasospasm)
Topical hemostatic agents
Promote clot formation on bleeding surfaces
Gelfoam; Thrombin; Avitene; Surgi-cel; Oxy-cel
Contralateral
Claudication
Bolus
Pertaining to the opposite side
Limping (FYI: often due to peripheral artery disease)
a dose of medication given all at once
Vasa vasorum
CAD
PVC
blood vessels that supply blood vessel walls
Coronary artery disease
Premature ventricular contraction
AAA
ASD
Abdominal aortic aneurysm
Atrial-septal defect
3 layers of artery/vein walls
Tunica intima
Tunica media
Tunica adventitia
Function of capillaries
Exchange of O2/CO2, wastes, and nutrients
3 similarities between arteries and veins
Same blood supply to vessel walls
Called: vasa vasorum
Regulated by autonomic nervous system
Connected by capillaries
5 characteristics of arteries
Thicker muscle layer (tunica media) Thicker-walled over all More elastic Maintain round shape when dissected Pulse is evident
5 characteristics of veins
More fragile than arteries One-way valves Fewer nerve fibers than arteries Lay flatter than arteries Smooth flow rather than pulsatile
Arteries
Veins
Flow away from heart
Return blood to heart
Pulmonary arteries
Send deoxygenated blood from the heart to lungs for oxygenation
Pulmonary veins
Carry oxygenated blood from lungs to the heart
