EXPERIMENT 2: VIRTUAL MODEL - THE LYMPHATIC SYSTEM

This experiment will use the virtual model to guide you through the macroscopic anatomy of the lymphatic system and vessels. Through this exploration, you will identify the placement of organs, nodes, ducts, and vessels of this complex 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.

i. 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 Lymphatic System option. Then select General Anato

my.

4. Click through the lymphatic system components.

Note: Zoom in on the lymphatic 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 respiratory system.

6. Click the “Depth” button to view the second layer of the lymphatic system. Note

that the second layer can only be seen when the virtual model is in the anterior

view (Figure 8).

Figure 8: Work your way through the lymphatic system to better understand the anatomical place ment and function of this system.

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

take a picture of the lymphatic system components listed below. Submit these

images to your instructor along with your post-lab questions.

a. Spleen

b. Thoracic Duct

c. Axillary Lymph Nodes -

Hint: Be sure to hover your mouse over the lymphatic system component to reveal its label in the image.

8. Once you have completed your overview of the general anatomy of the lymphatic system, answer the post-lab questions.
