The trachea branches off into two tubes going to each lung called the Bronchial Tubes.
the left and right bronchi
Two structures that belong to the respiratory system are the trachea (windpipe) and the bronchial tubes. The trachea carries air from the throat to the lungs, while the bronchial tubes divide in the lungs to deliver air to each lung's air sacs.
The two tubes leading into the lungs are the bronchi. They are branches off the trachea, and bring air into and out of the lungs.
The trachea or windpipe divides into the two primary bronchi which enter each lung. These further divide and subdivide into smaller and smaller bronchi finally forming tiny tubes called bronchioles that end in alveoli (air sacs that facilitate oxygen transfer from the lungs into the pulmonary capillaries).
This is part of breathing in, or inspiration. The trachea splits into the two bronchi (singular: bronchus) one of which goes to each lung.
Trachea
This is part of breathing in, or inspiration. The trachea splits into the two bronchi (singular: bronchus) one of which goes to each lung.
Bronchi
No trachea is not the lung.
Bronchi are the two tubes that branch off into each lung.
No, bronchioles are part of the respiratory system. They are small airways found in the lungs.
Nasal or oral cavity, pharynx,larynx,trachea. Trachea divides into to parts called primary bronchus. One goes to right lung second to left.Both bronki divide into 10 each. Then each divide into two and again into two and this process of dividing continues for 17 times. So to get the number you do 20*2*2-----17 times.Last you get the bronchioles. Then alveoli starts witch divide 6 time. So 20*2*2---23 times and you get the number of alveoli. Total surface area of alveoli is abot 100 square meters or about 1100 feet.
