What is the purpose of the ribs?

The rib cage protects the organs in the thoracic cavity, assists in respiration, and provides support for the upper extremities.

What controls your respiratory rate?

The respiratory centre in the medulla and pons of the brainstem controls the rate and depth of respiration, (the respiratory rhythm), through various inputs.

What muscles help you breathe?

From a functional point of view, there are three groups of respiratory muscles: the diaphragm, the rib cage muscles and the abdominal muscles. Each group acts on the chest wall and its compartments, i.e. the lung-apposed rib cage, the diaphragm-apposed rib cage and the abdomen.

Does the brain control the lungs?

Your brain constantly gets signals from your body which detect the amount of oxygen and carbon dioxide in your blood. Your brain will send signals to the muscles involved in breathing and adjust your breathing rate depending on how active you are.
