EXPERIMENT 2: VIRTUAL MODEL - THE CIRCULATORY SYSTEM

In the previous experiment, you examined the microscopic anatomy of the circulatory system. In this experiment, you will use the virtual model to explore the macroscopic anatomy of the circulatory system. This will allow you to better understand the locations and extent of the circulatory system.

PROCEDURE

1. Open the virtual model website.

2. Familiarize yourself with the virtual model. Navigate the model by using the commands below:

a. Select the body system of interest from the box in the upper left-hand corner of the model. Note that some body

systems may have multiple options for viewing (e.g., for the nervous system, you can select either the general

anatomy or the brain).

b. Hover your cursor over different areas on the model to display labeled terms.

c. Click on any component of the body to view a description of its function.

d. In the bottom right-hand corner of the model you will see a two magnifying glasses with a “+” at the bottom and

a “-“ at the top. Click on these buttons to zoom in and out of the virtual model.

e. When zoomed in, use your cursor to click and drag the virtual model to the area of interest.

g. Use the “Views” pop-up menu to change the orientation of the virtual model. These options may include the

anterior view, posterior view, lateral view, superior view, and inferior view of the virtual model. Note that not

all options may be available for each system.

h. Some systems may have multiple layers to explore. Click on “Layers” pop-up menu to access a deeper

layer of the system of interest if available for the system being observed.

3. After you are comfortable with the Virtual Model interface, select the Cardiovascular System option. Then select the

"Regions" button and select Veins and Arteries.

4. Click through the circulatory system components.

Note: Zoom in on the circulatory system to reveal all elements. Some components are only visible when you

zoom in.

5. Hover the cursor over different components to view the name. Click on each component to view a description of it.

Hint: Review the post-lab questions as you work through the circulatory system.

6. Click the “Layers” button to view the second layer of the circulatory system. Note that the

second layer can only be seen when the virtual model is in the anterior view (Figure 4).

7. As you move through the model, take a screenshot or use your cell phone to take a

picture of the circulatory system components listed below. Submit these images to your

instructor along with your post-lab questions.

a. Descending Aorta

b. Brachial Veins

c. Femoral Artery

Hint: Be sure to hover your mouse over the circulatory system component

to reveal its label in the image.

8. Once you have completed your overview of the general anatomy of the circulatory sys-

tem, answer the post-lab questions.
