Basics
Function:
The function of the respiratory system is to bring oxygen into your body. You need oxygen to survive. The respiratory system also helps your body get rid of carbon dioxide. In other words, oxygen from the air is diffused into the bloodstream while carbon dioxide from the blood stream is diffused into the air. We call this process breathing or respiration.Organs:
There are 3 major organs in the respiratory system: your Trachea, Lungs, and Diaphragm.
TRACHEA: The trachea also known as your windpipe is a cartilage tube composed of about c-shaped rings. The it's job is to get oxygen and carbon dioxide into and out of your lungs. When you breath in, oxygen goes down your windpipe and into your lungs. When you breath out, carbon dioxide goes up your wind pipe and out of your body.
LUNGS: The lungs consists of a pair of bronchi and millions of alveoli. The lower trachea divides into two creating the primary left and right bronchi. Gas coming into and out of the lungs enter them and get filtered through the bronchi. Each bronchi branch out further into the lung creating secondary bronchi, tertiary bronchi, and bronchioles. At the end of the bronchioles, there are small balloon like sacs called alveoli. The alveoli allow oxygen and carbon dioxide to move between the lungs and bloodstream. They are connected to pulmonary arteries and veins.
DIAPHRAGM: The diaphragm is what does the actual job of breathing. It is a sheet of muscle located under your lungs. It contracts to pull oxygen into and inflate the lungs and relaxes to push carbon dioxide out.
Interactions With Other Systems
The respiratory system mainly works with two other systems: the circulatory and digestive.

The respiratory system mainly works with two other systems: the circulatory and digestive.
Circulatory System
The circulatory system exchanges gas with the respiratory system. The process happens in the aveoli of the respiratory system. It is connected with veins and arteries from the circulatory system. Both oxygen and carbon dioxide is absorbed into and out of the bloodstream through the thin (one cell thick) walls of the alveoli. Oxygen from the respiratory system is need to oxygenate the blood of the circulatory system while carbon dioxide from the circulatory system needs to be taken out of the body through the respiratory system.Digestive System
The respiratory system, specifically the mouth and pharynx (two other organs in the respiratory system), also interact with the digestive system. In addition to being part of a path that brings gas in and out of the lungs, these two organs also aid in swallowing food and moving it along the digestive track. In other words, the mouth and pharynx play a part in both the digestive and respiratory system.
Analogy: Bronchi Are Like Trees

Bronchi are like trees because:
- they start as a single trunk and then branch out further and further as well as get smaller and smaller just like how the bronchi starts as one piece then eventually turns into millions of tiny bronchioles.
- the branches transport nutrients and water from the ground to the rest of the tree through the branches and trunk like how the bronchi transports oxygen from the air to the lungs(where it will be distributed to the rest of the body through the bloodstream) through the primary, secondary, and tertiary bronchi along with the bronchioles.
If bronchi were trees, the trachea would be the trunk of the tree. The bronchi would be the first few branches while the smaller branches would be the secondary, tertiary bronchi, and the bronchioles. As you can see, trees and bronchi are similar in multiple ways.
Structure and Function: Bronchi
The main function of the bronchi is to allow gas to move in and out of your lungs so you can respire or breath. In order to be able to do so, they have to have specific physical traits.
- The diameter of the bronchioles (the structure) play an extremely important role in controlling the air flow (the function). The diameter changes in size either to increase of reduce the flow of air. It does this to make sure you are getting the right amount of air in and out of your lungs.
- The bronchi branches out so many times filling up practically the entire lung (structure). The bronchi has to branch out this far to make sure the entire lung is being filled with air (function). If the bronchi only branched out a few times and stopped halfway through the lung, then it would be harder and take longer to push air out of the entire lung. A bronchi branches out around 20-25 times.
As you have read, the diameter of the bronchi as well as the amount of times it branches out helps make sure the bronchi is able to easily allow gas to move in and out of your lungs.
