Respiratory System:
Function:
The Respiratory System's function is to provide oxygen for the body and eliminates all carbon dioxide.
Organs:
The organs that make up the respiratory system are the lungs which bring oxygen in and out, the trachea which is a windpipe that carries the oxygen to the lungs, the bronchus that transport air through and from the lungs, and the diaphragm which contracts to pull air in and out.
Interactions w/ Other Systems:
The Respiratory System works with the Circulatory System by exchanging gases. The Circulatory System uses the oxygen that the Respiratory System brings in, uses it, then brings the leftovers (CO2) to the lungs again to breathe out. The ribs which are part of the Skeletal System interact with the Respiratory System by slightly expanding when breathing and protecting the lungs.
Analogy:
Explanation:
I chose a pump and a bike tire for this analogy. The function of the Respiratory System is to exchange gases in the body by giving oxygen to the body and disposing of carbon dioxide by breathing out. Now look at the function of a pump + bike tire. For this analogy, think of these two things as one item. The pump uses the air inside of it and gives it to the tire, allowing the tire to roll without flattening and to function in general. The tire eventually unintentionally disposes of this air from leaking, which means that you have to use the pump again to pump the air into the tire. The Respiratory System and the bike and pump are similar because they both exchange air and gases to function.
Structure and Function:
For this section I chose the diaphragm. The diaphragm is the muscle that contracts and relaxes the lungs when you breath. This organ is looks like a dome made of muscles located just below the lungs. The diaphragm is dome shaped to fit at the bottom of the lungs like a puzzle piece and perfectly pump the lungs. If the diaphragm was a different shape say rectangular instead of round and smaller or bigger, I think that the lungs might not contract and relax in the same length or measure or might pump and release oxygen too much or too little.
