Lab: Blood Vessels DUE: 11/27 Name: ______________________________ Period: ____
The cardiovascular system consists of the blood, the heart, and the blood vessels. They provide transport to
all parts of the body. Oxygen is carried from the lungs to the arteries, arterioles, capillaries, venules, veins,
and then back to the heart. The goal is for the blood to become oxygenated. In dissection, the arteries have
been injected with red dye and the veins with blue to represent how rich the blood would be in oxygen.
Part I: Blood Vessel Anatomy.
Cross-sectional views of an artery and of a vein are shown here. Identify each and note the structural details
that enabled you to make the identifications. Also, complete the chart below.
Tunics or Coats
Location:
Tunica interna or intima
Tunica media
Tunica externa or adventitia
Part II: Arteries
Label the major systemic arteries of the human body.
Example:
Part III: Veins
Label the following major systemic veins of the human body.
Part IV. Hepatic Portal System.


Label the anatomy of the hepatic
portal system.
Compare the role of the hepatic
vein versus the hepatic portal vein.
