• Blood --> capillaries --> alveoli --> bronchioles --> bronchi --> trachea --> pharynx --> oral cavity --> air

• circulatory system --> digestive system --> respiratory system --> solar system

• heart--> lungs--> brain--> heart

The muscles that are responsible for allowing our lungs to expand and contract are:

• diaphragm and heart

• intercostal muscles and heart

• oxygen and carbon dioxide
