lungs
Air enters the respiratory system through nostrils. Nostrils, also called external nares, are the two external openings of the nasal cavity. They admit air to the lungs and smell to the olfactory nerves. Ears transmit sound waves to the internal ear while mouth allows food to be ingested. Alveoli are the tiny balloon-like structures where actual gaseous exchange takes place and they are present inside the lungs.
