which layer of the larger blood vessels is made up of endothelium?
tunica adventitia
tunica media
tunica intima
tunica albuginea
question 11

the outermost layer of the larger blood vessels is the tunica
media.
intima.
adventitia.
intermedia.
question 12

the internal iliac artery supplies blood to the
pelvis.
leg and foot.
head and upper extremities.
fingers.

Explanation:

• Question 10: The tunica intima is the innermost layer of blood vessels and is composed of endothelial cells. The tunica adventitia is the outer - connective tissue layer, the tunica media is the middle - smooth muscle layer, and the tunica albuginea is not a layer of blood vessels (it is a layer in some other anatomical structures like the testis).
• Question 11: The tunica adventitia is the outermost layer of larger blood vessels. The tunica media is the middle layer, the tunica intima is the inner layer, and there is no tunica intermedia in the context of typical blood - vessel layers.
• Question 12: The internal iliac artery supplies blood to the pelvis. The external iliac artery gives rise to vessels that supply the leg and foot. The subclavian and carotid arteries (among others) supply the head and upper extremities, and digital arteries supply the fingers.

Answer:

• Question 10: tunica intima
• Question 11: adventitia
• Question 12: pelvis
