The alveolar capillaries are around the alveoli - also inside the lung
Have a look at the wiki pages - there are some nice pictures and should give you the idea. The windpipe (trachea) divides into the two main bronchi (left and right) and these subdivide into smaller bronchi and smaller and smaller ... until you get to the bronchioles.
The bronchioles also divide and you eventually get to respiratory bronchioles and from these, the alveoli emerge. The capillaries are wrapped around the alveoli.
