Flashcards in Arteries Deck (18)
Veins carry blood
TOWARD the heart
*they receive blood from nearby structures.
Tunica intima are ________ cells
Tunica intima:endothelial calls
Subendothelial layer of loose connective tissue,
Deepest layer, closest to blood
Tunica media are _______ cells
Tunica media: smooth muscle cells
Elastic and collagen fibers,
Separated by internal elastic lamina
*veins so not have internal elastic lamina
Arteriovenuos malformation defined
Direct connection of arterial and venous circulation
Arteries carry blood
AWAY from the heart
*they supply blood to structures
Two arteries join..
What is the advantage?
Arteries that DO NOT follow the "classic" circulation pattern.
Together to feed an anatomical area
The body thinks 2 arteries should go into that area.
Arteriovenous malformation defined-
Direct connection of arterial and venous circulation.
Throughout body in small vessels.
In several physiologic processes.
The 3 layers of arteries
The tunica media and tunica intima are seperated by
The tunica media and tunic adventitia are seperated by
Internal elastic lamina
Exernal elastic lamina
Vessel within a vessel
*small vessels within that supply the adventitia
