the organ that helps us to breathe are the lungs and intercostal muscles.Intercostal muscles can be divided into 2 types.External intercostal muscle and internal intercostal muscle.Both of this muscles are located between the ribs,connected to each other but performed diffrent functions.During INHALATION, the 'organ' that takes part are the diaphragm and external intercostal muscle.As you breathe in oxy, the lungs expanded.So, in order to allow inhalation to take place, the diaphragm needs to contract by lowering itself downward.As for external intercostal muscle, it helps the ribs to expand forward and upward at the same time.This is to increase the lungs volume and allows inhalation to take place.
During Expiration, the abdonimal muscle and the internal intercostal muscle take part.To expire, the pressure inside the lungs must exceed the atmospheric pressure.In order to do so, the abdominal muscle needs to contract and create pressure inside the lungs.As for internal intercostal muscle,it lowers the rib cage downward and backward(inferior and posterior) to reduce the lungs' volume.
Expiration can be passive and active process.Passive here means the muscles (abdominal and internal intercostal muscle) does not contract.Active process is when a person exhale as hard as he/she could which needs the contraction of both exhalation muscles.
Hope that helps ya..

The only organ that helps you breath is your lungs. There are two muscle groups that help breath, the diaphragm and the intercostal muscles (the muscles between the ribs). The diaphragm will move up and down causing air to be inhaled or exhaled. When you breathe in you are increasing the pressure in your lungs, the muscles help with this. Then the muscles relax and you breathe out, this will equalize the pressure in your lungs with the pressure outside.

Lungs... I think the diaphragm helps too but I don't think it's an organ.

But what organ system is it that helps you breathe?

I think the answer you are looking for is the diaphragm, located just under your lungs.

your lungs ... clearly... but also your diaphram as this causes the lung to inflate drawing oxgen in.
Additionaly you throat and in a key fnction your brain... as it tells everything what to do...
