ONE:

Patience gave a good explanation of inhalation and exhalation and how connects with Boyle's Law. And with describing asthma she connected it to Boyle's Law very nice. Bronchitis also is related and is an inflammation of the lining of the bronchial tubes, which carry air to and from the lungs. People with bronchitis often cough up thickened mucus. Can be viral or bacteria infection. The inflammation of the bronchi is caused by inhaling toxic irritants or cigarette smoke. Can be acute asthma that develops fast but it clears in 14 days. Has the same symptoms as a cold: sneezing, coughing, pain upon inhalation, and fever. Then we have chronic bronchitis where the exposure to the irritants was long term, doing substantial damage to the bronchi. There will be large amounts of mucus in the bronchi obstructing the air exchange, along with a cough lasting 3 months or more. Those will do permanent changes with the bronchial wall that will thicken. The lumen will become narrower, and there will be increase production in mucin-secretin cells of the bronchi. Chronic bronchitis is one of reasons for COPD and emphysema. Both situations makes it difficult to breath. During inhalation the bronchi being narrow will bring less oxygen for the exchange, as well as exhaling will be harder. Airways become obstructed lead to frequent infections.

TWO:

          This paper was well written and informative. You went into detail a little too much on certain topics but overrall good job. You transitioned well between paragraphs and topics. You also used good grammar. A topic that can relate to the process of breathing and the respiratory system is sinusitis. Sinusitis is the swelling, or inflammation, of the tissue lining the sinuses. Sinuses are usually filled with air but when they become blocked they become filled with germs and fluid, which can cause infection. The common cold, and allergive rhinitis are two conditions which can cause the sinuses to become blocked. There air several types of sinusitis: acute sinusitis, subacute sinusitis, chronic sinusitis, recurrent sinusitis. About 37 million americans suffer from atleast one episode of sinusitis each year according to Webmd.com. In children, common environmental factors that attribute to sinusitis include: allergies, illnesses from other children at daycare or school, pacifiers, and smoke in the environment. Some primary symptoms include: facial pain/pressure, nasal stuffiness, nasal discharge, loss of smell, cough/congestion. To be diagnosed with sinusitis the doctor will give you a physical examination, and review your symptoms. The exam may include the doctor feeling the sinuses for tenderness. Other diagnostic test may be performed including: allergy testing, CT scan of the sinuses, and blood work.
