aka windpipe, from the larynx travels down to its length (10-12 cm, or about 4 inches) to the level of the fifth thoracic vertebra, approx mid chest

made up of C-shaped rings of 16-20 hyaline cartilage

the right and left primary bronchi are formed by the division of

smalled subdivisions of the main bronchi within the lungs and are the direct routes to the air sacs

resemble as bunches of grapes and they make up the bulk of the lungs

walls of the alveoli are composed largely of a single, thin layer of

located in the thoracic cavity protected by the ribs

what membrane encloses each lung

two layers of serous membrane
