artery (blood vessels that take blood away from the heart; arteries take blood to an
organ/tissue)
veln (blood vessels that take blood to the heart; veins drain blood from an organ/tissue)
venous valves
tunica interna (TOO-ni-ka in-TER-nah) (also called tunica intima in-Tl-ma) (This is
the innermost layer of a blood vessel wall. It is made of endothelium-simple squamous
epithelium) and a subendothelial layer of areolar connective tissue)
endothelium (this is a layer of simple squamous cells that line the inside of all
blood vessels; it allows the smooth flow of blood (prevents turbulent blood flow)
subendothelium (this is a layer of areolar connective tissue "under" the
endocthelium; it allows the smooth flow of blood (prevents turbulent blood flow)
internal elastic lamina (LAM-i-na) (This is one of two layers of elastic fibers
found only in muscular arteries-not elastic arteries. This layer separates the tunica
intima from the tunica media. This layer is very thin or absent in veins.)
tunica media TOO-ni-ka MĒ-dē-a) (This is the middle layer of a blood vessel wall. It is
made of circularly arranged layers of smooth muscle cells.)
external elastic lamina (LAM-i-na) (This is one of two layers of elastic fibers
found only in muscular arteries-not elastic arteries. This layer separates the tunica
media from the tunica externa. This layer is very thin or absent in veins.)
tunica externa (TOO-ni-ka eks-TER-na) (also called tunica adventitia) (This is the
outermost layer of a blood vessel wall. It is made of areolar connective tissue with elastic
and collagen fibers. This layer helps anchor the blood vessel to other structures.)

CLEAN UP:
1. When you have completed the lab, please look around the lab room and make sure all
models, medical tape, sharpies, slide trays, etc. have been returned to the correct place
in lab.
2. Wipe down your table as needed.
3. Scoot in your chair.
