1. The upper respiratory system includes everything fromthe larnyx to the nasal passages and the exernal nose, while thelower respiratory system starts with the trachae and continues tothe lungs. Therefore you answer is C.

3. When you are inhaling and exhaling the pressure insideyour lungs changes with the use of the diaphragm. When youhave a ballon the and you let go of the end and all the air spitsout, this is because the air inside is of greater pressure then theatmosphere, so the air leaves the ballon.
