2. The Function The function of the respiratory is that it supplies blood with oxygen for the blood to deliver oxygen to all parts of the body.

3. Major Organ Structures Lungs- Paired organs in your chest that add oxygen to your blood and then it carries it to your cells. Trachea- A bony tube that carries air from your mouth and nose to your lung (commonly know as the ‘windpipe’) Bronchi- Two tubes inside your lungs divided from the trachea that carry air to and from the lungs. Diaphragm- A sheet like muscle that contracts downward into the abdomen which enlarges the chest, allowing air to fill the lungs.

4. Other important Alveoli- Tiny air sacks within the lungs where oxygen and carbon dioxide are exchanged. Pharynx- Moves air into lungs and food into your stomach. Epiglottis- A piece of cartilage that makes sure foods doesn’t enter your lungs.

5. Diseases That Affect This System Asthma- A chronic condition that can block your lungs and make it hard to breath. Can not be cured but has fast acting medication and long term. Influenza- Fever, headache, and soar throat. Is cured by medicine and can be vaccinated. Pneumonia- Inflammation of the lungs. Can be treated by medication but can be life threatening the best thing is to get vaccinated. Bronchitis- Increased secretion of mucus in the bronchi which blocks it causing a cough.

6. Relationships between other systems Nervous system- The brain monitors respiration and blood and gas levels. Excretory system- It eliminates water vapor through exhalation. Cardiovascular system- they work together in getting oxygen to tissues and transporting co2 out.
