P · Accepted Answer

1. Why is the trachea reinforced with cartilaginous rings?
The cartilaginous rings provide the support to the trachea and prevents its collapse and keeps the airways open for breathing process.
2. Describe the path a molecule of oxygen takes to get to body tissue, starting with the 
Nose-Nasal cavity-Paranasal Sinuses (dust will be trapped)-Pharynx-Larynx-Trachea-Bronchi-Bronchioles-Alveolar duct-Alveoli-blood stream.
3. What is asthma
Asthma is a disease where the persons air sacs will get inflamed and results in excess mucus production and which makes breathing difficulty.
4. What structural features of alveoli make them an ideal place for gas exchange? ” 
1. The surface of the alveoli is very thin made of one row of cells, which makes the shortest distance for gaseous exchange.
2. The alveoli is surrounded by the blood capillaries through which the oxygen enters into the blood stream.
5.   Why is mucus present in the trachea? ”
The  mucus present in the trachea traps and prevent the entry of microorganisms and debris entry into the lungs.
6.  What is the specific function of the cilia on the walls of the trachea
The cilia helps to push the trapped microorganisms and debris out of the trachea. 
7. What happens to the pressure inside the thoracic cavity when the diaphragm contracts? What effect does this have on the lungs?
The pressure inside the thoracic cavity  decreases when the diaphragm contracts.  The pressure inside the lungs also decreases resulting in Breathing in mechanism.
8. What causes a collapsed lung
Lung injury by gunshot, chest wound by knife, rib fracture and in some cases by air blisters results in collapsed lung.
9. Is a collapsed lung functional? Why or why not?
The collapsed lung is functional if it is properly treated by surgery, oxygen therapy, Atelectasis treatment and other process. These treatment will re-inflate the collapsed lung for gaseous exchange.
10. Describe the interior lining of the trachea
The trachea is lined with mucous membrane layer composed of cilia , submucosa and adventitia. The mucus generated from the trachea traps the microorganisms and debris from entering into the lungs.
11. Were there many or few vessels serving as conduits between the lungs and the heart? Why is this important
Yes many vessels are conducts between lungs and heart. Because there is need for the supply of blood which carries oxygen and removal of the carbon dioxide takes place. The gaseous exchange takes place at lungs from lungs oxygen is supplied via blood flow to the heart.
12. Describe the function of the diaphragm during inhalation and exhalation
During Inhalation the diaphragm contracts and flattens-Breathing in
During Exhalation the diaphragm relaxes- Breathing out
13. What is the function of the ureter?
Carry Urine from kidneys into the urinary bladder.
