Learning objectives:
1. Identify the structural layers of arteries and veins.
2. Distinguish between the structure of arteries and veins.
3. Explain the factors that affect arterial blood flow and blood pressure.
4. Define shock, and identify the signs of shock.
5. Identify key blood vessels of the cardiac, systemic, and pulmonary circulations.
Introduction:
Blood is transported around the body in 3 different types of blood vessels: arteries, capillaries,
and veins. Each blood vessel is composed of 3 layers of tissue. Blood pressure and flow
depend on multiple factors. There are a number of mechanisms by which shock can occur.
We will track blood through the pulmonary and systemic circulations noting the major arteries
and veins in our path.
Assignment:
Part 1 Complete the activities in the following sections of Anatomy.TV Cardiovascular
system: Blood vessels, Blood flow and Pressure, Circulatory Pathways, Vessels of the
Trunk, Vessels of the Head and Neck, Vessels of the Limbs
You will then work through the material and activities by scrolling down on the right. This will
allow you to see and work through all activities for that section.
Part 2 Complete the lab report.

, -Explain the factors that influence the exchange of material between the blood within
capillaries and the interstitial fluid surrounding body tissues.
2. Procedure:
Briefly discuss the procedure for this lab.
-Distinguish between the structure of arteries and veins.
-Identify factors that influence cardiac output, blood flow, and blood pressure.
-Identify essential blood vessels of the cardiac, systemic, and pulmonary circulations.
-Identify the structures of the heart.
3. Data and Details:
