What are the functions of blood vessels?

transportation of materials (hormones, nutrients, oxygen, waste)

Put these blood vessels (capillaries, elastic arteries, muscular arteries, medium-sized veins, large veins, arterioles, venules) in order of blood flow starting within an organ in which blood is returning to the heart.

1. capillaries

2. venules

3. medium-sized veins

4. large veins

In heart

5. elastic arteries

6. muscular arteries

7. arterioles

Arteries/arterioles carry blood ___________ the heart.

away from

Veins/venules carry blood ___________ the heart.

Name the 3 tunics associated with veins and arteries

1. tunica intima

2. tunica media

3. tunica externa

What are the 3 tunics primarily made of?

1. tunica intima- simple squamous

2. tunica media- smooth muscle

3. tunica externa- collagenous connective tissue

Which tunic is much thicker in an artery v.s. a vein and why?

tunica media is thicker because it has a lot of smooth muscle to manage high blood pressure surging directly from heart

How are elastic arteries structurally different from muscular arteries?

Elastic: larger lumens, thinner walls, higher density of elastic fibers in tunica media

Muscular: smaller lumens, thicker walls, less elastin, smooth muscle in tunica media
