Through nose.
The oral cavity is bordered by the lips, cheeks, tongue, palate, and oropharynx. It is the opening through which food enters the digestive system and air passes into the respiratory system.
diffusion of air through air sacs
The nasal cavity belongs to the respiratory system.
The nasal cavity is connected to the pharynx, or throat, through the openings of the nostrils. Air passes through the nasal cavity and into the pharynx for further passage into the respiratory system.
The upper respiratory system (where air enters and exits the body) is composed of the nasal cavity, pharynx, and larynx. The lower respiratory system (where the air moves to be processed) consists of the trachea, the bronchi, and the lungs. So the answer is either the nose and mouth, or the trachea, depending on how you meant the question.

the respiratory system since that is where your lungs are located
No respiratory organs. They use an internal cavity.
The respiratory system absorbs oxygen. Oxygen is inhaled through the nose and mouth, passes through the trachea, and enters the lungs where it is absorbed into the bloodstream through tiny air sacs called alveoli.
