bronchi
The right and left primary bronchus which are the branches of trachea.
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.
Larynx. After laryngopharynx, the air enters you larynx. From larynx, it goes to your trachea. You can be easily choked by pressing the larynx. Larynx has got narrow and long slit to produce the voice.
trachea
Structure of the tracheaThe trachea is lined by cartilage and divided into two branches. These two branches are called the bronchi. The left bronchus enters the left lung and the right bronchus enters the right lung. Each bronchus is further divided into around 25 smaller branches. These smaller divisions of bronchi are known as the bronchioles. The bronchioles carry air into the alveoli.
The respiratory system.
i dont no the trachea is located just below the pharynx. when we breath the air enters the pharynx, the trachea, the bronchus,the bionchioles, the alveolus and finally enters th lungs so the trachea moves air into the bronchus.The trachea is made up of ring of cartillage which keep the trachea opened when we inspire and expire
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.
it goes to the butt
trachea
Oxygen enters the respiratory system through the mouth or nose. It travels down the trachea and enters the lungs via the bronchial tubes. In the lungs, oxygen is diffused into the bloodstream through the alveoli. Oxygen-rich blood is then pumped by the heart to the rest of the body for cellular respiration.
Passages through which air enters the lungs is called the bronchi which branch off of the trachea.
