Peripheral Vasculature Flashcards
(116 cards)
What type of blood vessel is strong and flexible
Arteries and Arterioles
What type of blood vessel is a high pressure system
Arteries and arterioles
Blood flows from arteries/arterioles to arteries/arterioles
Arteries to arterioles
Are veins or arteries less elastic
Veins
Blood flows from venules/veins to venules/veins
Venules to veins
Which blood vessel is a low pressure system
Veins and venuoles
What are the links between arteries and veins
Capillaries
What are the webs of microscopic vessels
Capillaries
This is the main exchange between blood and tissue fluids, gases, waste, etc.
Capillaries
What are layers of the vessel walls from the inside to outside
Lumen Tunica Intima (inner) Tunica Media (middle)(muscle) Tunica Adventitia (outer)
Tunica Media is thicker in which vessel
Arteries
In arteries the tunica media serves which purpose
Holds shape of vessel and maintains pressure
Which vessel does not have valves
Arteries
Arteries do not have valves so how is the flow controlled
Controlled by systole and muscle contractions
Which vessel has a thinner tunica media
Veins
Having a thin tunica media means that veins have which quality
Compressibility
Do veins have valves? If so where are they located
Yes
In upper and lower extremities
What do valves do in the body
Keep blood flow in one direction (towards the heart)
The body has both —— and —— venous systems
Deep and superficial
The blood supply to the arms comes from the
Branches of the aortic arch
What are the branches of the aortic arch from first to last
Brachiocephalic (innominate)
Left common carotid artery
Left subclavian
What is the first branch off of the aortic arch
Brachiocephalic (innominate)
Which branch of the aortic arch is the most anterior in postion relative to the others
Brachiocephalic (innominate)
What is the second branch of the aortic branch
Left common carotoid artery
