Peripheral Vasculature Flashcards
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
Which branch is the middle branch of the aortic arch
Left common carotid artery
The left common carotid artery is —— to the innominate branch
Middle and posterior
What is the third branch off the aortic arch
Left subclavian
Which branch is the most posterior on the aortic arch
Left subclavian
The aortic arch goes in which direction in the body
Left and posterior
Which aortic branch supplies blood to the right arm
Brachiocephalic trunk (innominate)
The brachiocephalic trunk divides into what two branches
Right common carotid artery (up right side of neck)
Right subclavian artery (right arm)
Which aortic branch supplies blood to the left arm
Left subclavian artery
Subclavian arteries travel —— towards the shoulders
Horizontally
The subclavian arteries become the —— artery at about what level
Axillary artery at about the humeral head
What is an extension of the subclavian artery
Axillary artery
Which artery originates at the level of the humeral head
Axillary artery
Which artery is a short segment that travels along the axilla
Axillary artery
In the region of the upper/mid humerus the axillary artery becomes the what
Brachial artery
Which artery continues to the elbow
Brachial artery
At the elbow the brachial artery divides into what two arteries
Ulnar artery
Radial artery
Which artery travels along the lateral forearm to the wrist
Radial artery
Which artery is located on the thumb side of the forearm
Radial artery
Which artery travels along the medial forearm to the wrist
Ulnar artery
P.U. - pinky and ulnar
What arteries are distal extensions of the radial and ulnar arteries
Palmar arteries
Which arteries form deep and superficial arches in the hand
Palmar arteries
What arteries go to the fingers
Distal arteries
