Virtual Pig Dissection – The Respiratory System
This is a “virtual dissection” where you will visit each of the different
parts of the pig’s body to get an idea of what the parts are for. To get
started, go to http://www.whitman.edu/academics/departments-andprograms/biology/virtual-pig and click on “Respiratory System”.
Answer the questions below either by copying and pasting this sheet
onto one of your own, or printing off a copy to write your answers in.
You are doing this so you’re somewhat prepared for Wednesday’s
dissection.
1. On the first slide where it shows the pig’s nose, it gives a
definition of what the respiratory system is. Copy this.
2. Click to the next part. What is the tube that carries the air
directly to the lungs?
3. What is the tube that carries the food to the digestive system?
4. Click to the next slide and check out the lungs. Click next
again, and sketch and label the different parts that are seen in
this picture.
5. Click to dissect the lungs. Using proper terms, tell what
happens to the air once it has passed through the bronchi.
6. Dissect further and read through this part. Click to move on to
the diaphragm. What is the thoracic cavity? How does the
diaphragm help the pig to breathe?
Quiz
You are done with the virtual tour, and now it’s time to take the test to
see what you have learned. Copy out the proper definition of what
each of the following words if for.
1. Lungs
2. Bronchi
3. Diaphragm
4. Nares
5. Trachea
When you’re done this part, please take a look through the circulatory
system, paying attention to the cow heart. We are dissecting pig
hearts, although there are lots of similarities.
Familiarize yourself with the heart, as our hearts are very similar to
pigs in structure and function to ours. **There is a possibility of a quiz
on Tuesday on the heart**
