There are 4 types of lung over expansion. I just don't recall there names, so can anyone help me out in this.
I can only remember only 2 of them which is gase empolism, pneumothorux. I want the name of the other 2 (the one the air enter the cavity or the gap of the heart and the other one is the one the air found under the skin around the neck)
Thanks a lot for your help
