In the email that I sent you this morning you have all the information you need for your class.
Here you have the answers for the exercises that you have to do in your notebook.
There is also this video that you can watch to increase your knowledge on this matter. There are some images that are tough, but the doctor explains this subject so well that I think it's worthy watching it.
Miss you all,
Hope you are OK
Your teacher,
Irene
