larynx , trachea , bronchioles, air sacs , and then diaphragm
Oxygen passes through the nasal cavity, pharynx, trachea, bronchi, bronchioles, and finally reaches the alveoli in the lungs where gas exchange occurs with the bloodstream.
Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.
Oxygen is the gas that passes from the lungs to the bloodstream.

The air sacs in the lungs where oxygen passes into the bloodstream are called alveoli. These tiny, thin-walled structures are surrounded by a network of capillaries where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be released.
Gills are the respiratory structures in aquatic animals that remove oxygen from water. They are specialized tissues with a large surface area that allows for efficient exchange of gases. Water passes over the gills, and oxygen diffuses from the water into the bloodstream of the aquatic animal.
Oxygen is the gas that usually passes into cells. It moves by diffusion from the bloodstream.
Oxygen passes out of the bloodstream into tissues where it is used for cellular respiration, the process that generates energy for cells. Oxygen is critical for the production of ATP, which is the main source of energy for the body.
The gas that passes from the bloodstream into the lungs is called carbon dioxide. Carbon dioxide is transported from the tissues to the lungs via the bloodstream, where it is exhaled out of the body during respiration.
Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.
Oxygen is passed from the air to the blood through the process of diffusion in the alveoli of the lungs. The alveoli are surrounded by tiny blood vessels called capillaries, where oxygen diffuses into the bloodstream and carbon dioxide diffuses out of the bloodstream to be exhaled.
