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
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.
Blood Vessel or Structure
Superior and Inferior Vena Cava
Pulmonary semilunar valve
Aortic Semilunar 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
Receives blood from the left atrium
Transports blood to the lungs
Receives blood from the vena cava
Right and left atria
Contraction results from SA node impulse
Transports blood from the lungs to heart
Receives blood from the pulmonary veins
Receives blood from the left ventricle
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)....
