Circulatory System Self-Assessment Activities
Directions: Complete each one of the questions as directed.
1. Trace the flow of blood through the vessel types of the circulatory system. Starting with blood in the capillaries (#1), determine the sequential order of vessels and put the numbers in the “Sequential Order” column.
Blood Vessel Type
Sequential Order
Capillaries
1
Arterioles
5
Veins
3
Venules
2
Arteries
4
2. Trace the flow of blood through the structures of the heart, its associated blood vessels, and to the lungs and back. Start with the blood returning to the heart via the superior and inferior vena cava (#1) and determine the sequential order in which the structures and blood vessels will be encountered by the blood.

Left Ventricle
11
Aorta
13
Right Atrium
2
Left Atrium
9

6
Aortic Semilunar Valve
12
Tricuspid Valve

3. Identify each one of the following structures on the basis of its description or function.
Blood Vessel or Heart Structure
Description or Function
Left Ventricle
Receives blood from the left atrium
Pulmonary arteries
Transports blood to the lungs
Right atrium
Receives blood from the vena cava
Right and left atria
Contraction results from SA node impulse
Pulmonary veins
Transports blood from the lungs to heart
Left atrium
Receives blood from the pulmonary veins
Aorta
Receives blood from the left ventricle
Pulmonary arteries
Receives blood from the right ventricle
Right atrium and ventricle
Separated by the tricuspid valve
Left Atrium and Ventricle
Separated by the bicuspid valve
4. Determine if the blood in each one of the following heart regions or blood vessels is “red” (relatively high oxygen content) or “blue” (relatively low oxygen content)....
