Bronchitis
When the bronchi and bronchioles become ________ or _________________ will occur, along with the production of additional ______.

What makes carbon monoxide so deadly is the fact that it binds to ________ more efficiently than oxygen (approximately _____ times better!), preventing red blood cells from delivering oxygen to the cells of the body.
Early symptoms of carbon monoxide poisoning include _________, _________, _______ and ______. _____, damage to ________________ and _______ will soon follow if the person isn't allowed to get fresh air.
High Altitude Breathing
As you _______ altitude, pressure __________, allowing oxygen molecules to ______ further apart, making the amount of oxygen available in each breath _______. When a person moves to a higher elevation, their body cannot extract enough oxygen from the air to meet their ___________ needs and the result is, "_______________" or _____. Symptoms will include ___________________ from even the slightest exertion, along with ________ and _______.
The body will respond first by _________________________________, which helps to bring more oxygen in contact with the alveoli.

Scuba Diving

When scuba diving, pressure ________ as the diver goes further underwater. As the pressure increases, the diver's bloodstream and body tissues _________________________, including nitrogen. Beyond depths of 40-60 metres, the increased nitrogen in the bloodstream can cause _________________ also known as "_______________________".

Effects of Smoking on the Respiratory System
Nicotine can ______________ and interfere with ____________ production, preventing the _____________ of air as it enters the lungs.
Chemical substances are deposited on the _________ walls, which can lead to ________ cells. This is a region where ___________ frequently develops.
Smoking will lead to ________. Emphysema is when the __________ lose their __________, causing air to get ____________ in the lungs, preventing ___________ air from getting in.
Smokers may also experience a high occurrence of the following:
Bronchitis - caused by infection from _____ and ___ particles. Excessive _____ is secreted in the _______ and the airways become partially ________. This is the cause of “_________________” that is accompanied by a thick _____________.
Heart Disease – decreased concentration of ________ in the blood means the _______ has to work harder.
