Tunica internal/ intima components
- endothelium
- basement membrane
- basal lamina
- internal elastic lamina
endothelium in bv function
innermost lining, squamous epithelium
basement membrane function
-physical support for epithelial layer
what attaches endothelium to bv?
basement membrane
basement membrane structures
collagen fibers
basal lamina function
anchors endothelium to underlining connective tissue
internal elastic lamina function
-seperates t internal from t media
internal elastic lamina structure
thicker in artery
thick layer of smooth muscles
tunica media structure
muscular and connective tissues, elastic fibers, , thick smooth muscles
function of tunica media
adjust diameter of lumen -> blood flow and bp (vasodilation and vasoconstriction)
tunica externa structure
elastic and collagen fibers
what separates t external from t media
external elastic lamina
vaso vasorum
-vessels within vessels
tunica external function
anchor vessels to surrounding tissue
what bv has high compliance?
arteries
high compliance meaning
large volume of blood ejected so it expands w/o stretching
what does the t media allow in arteries
increase in diameter
which bv has a think tunica media
elastic/ conducting artery
which artery is the internal and external elastic laminae well defined?
artery
where is elastic lamella a yellow colour?
elastic artery/ conducting artery
what artery does the aorta have?
elastic artery/ conducting artery
location of elastic artery/ conducting artery
aorta, pulmonary trunk, subclavian, common carotid, iliac carotid and brachiocephalic
what artery does the pulmonary trunk have?
elastic artery/ conducting artery
what artery does the brachiocephalic have?
elastic artery/ conducting artery
what artery does the subclavian have?
elastic artery/ conducting artery
what artery does the common carotid have?
elastic artery/ conducting artery
what artery does the iliac carotid have?
elastic artery/ conducting artery
which artery is the pressure reservoir?
elastic artery/ conducting artery
muscular/ distribution artery size
medium
muscular/ distribution artery function
