Year 7 are dissecting

Year 7 pupils got to examine the heart and lungs of lambs today. 

First they identified the organs. 

And labelled them

Making sure to identify all they could. 

Once everything was clear

They had the opportunity to cut into the organs

And examine their structure

This included using a syringe to blow up sections of the lungs. 

Which would turn bright pink if you inflated a bronchiole. 

They examined the trachea

And the heart

The diaphragm

And the oesophagus 

And identified the difference between arteries and veins

These lambs organs are just a little smaller than human ones. 

Some potential surgeons or butchers were identified and a couple who discovered a more queasy side.
