When you breathe your chest rises and falls with each breath because under you rib cage is the diaphram that expands causing your chest to rise with each breath you take in and when you exhale your chest falls because your diaphram is pushing the air out.

What happens to the chest cavity when your breathing?
Under normal inspiration the chest wall stays relatively still, only the abdomen moves because of diaphragmatic motion. However, when you take a deep breath the intercostal muscles and the scalene muscles contract. This causes the chest wall to expand outward(due to the intercostals) and move upwards(due to the scalenes).
What do the intercostals do?
allows your ribs to move up and down when you breath the intercostal muscles contract.these pull the ribcage upwards.so the chest increases in volume when we breath out the intercostal muscles relax which lowers the ribcage.the chest decreases in volume see the diagram below for help The intercostal muscles are located between the ribs and they lift the diaphragm allowing oxygen to flow in and out of the lungs. Basically, they aid in breathing.
What layer of muscles move up and down when you breath?
The diaphragm is a muscle that moves or pushes up your lung when you exhale and down when you inhale in order to allow more space for oxygen to fill your lung. Also, your chest expands as you breath in and relax as you exhale.
