EXPERIMENT 5: VIRTUAL MODEL - THE HEART

The heart is located in the mediastinum, a cavity located between the lungs. The primary function of the heart is to accept deoxy genated blood from the body, pump this blood toward the lungs for oxygenation, and deliver the oxygenated blood back out of the heart to be circulated throughout the body. In this experiment, you will use the virtual model to better understand the structure of the heart.

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. Then select the Heart.

4. Click through the heart.

Note: Zoom in on the heart to reveal all elements. Some components are only visible when you zoom in. Re-

member that you will need to reorient the virtual model to observe the entirety of the heart.

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 heart.

6. Click the “Depth” button to view the second layer of the heart. Note that the second layer

can only be seen when the virtual model is in the anterior view (Figure 9).

Figure 13: Work your way through the heart to better understand its anatomical placement and function.

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

ture of the heart components listed below. Submit these images to your instructor along

with your post-lab questions.

a. Myocardium

b. Mitral Valve

Hint: Be sure to hover your mouse over the heart component to reveal its

label in the image.

8. Once you have completed your overview of the heart, complete the post-lab questions.
