these are the pipes by which oxygen enters the lungs and co2 exits
The respiratory system takes in oxygen and gets rid of carbon dioxide so you can breathe.
The respiratory system takes in oxygen and gets rid of carbon dioxide so you can breathe.
The respiratory system exchanges oxygen by inhaling air through the nose or mouth, where oxygen is taken into the lungs and absorbed into the bloodstream. Carbon dioxide, a waste product, is then expelled by exhaling air out of the lungs. This exchange occurs in the alveoli, tiny air sacs in the lungs where the transfer of gases takes place.
Your lungs
Respiratory system is the system involved in respiration (the process by which an organism takes in oxygen and releases carbon dioxide).
bronchi (singular bronchus) --Allison
Block your nostrils/nares and mouth, or obstruct the trachea/windpipe. The nostrils/mouth are only ways in which your body takes in air and the trachea is the only passage that delivers air to the lungs. Therefore, blocking them would effectively cut off your air supply.
The respiratory system moves oxygen in and carbon dioxide (CO2) out.
the lungs Nova Net answer = Respiratory System
Your respiratory system starts at at your nostrils and mouth, where oxygen goes in. It then passes into the pharynx and trachea and then into the right and left bronchi, which branch into smaller bronchioles, and finally into the millions of tiny alveoli. Actual gas exchange takes place in the alveoli.
Pharynx is the common organ in both systems because it takes food and air.
