Respiratory system?

where are the alveolis and the capillary in relation to the lungsRespiratory system?
The alveoli are inside the lung
The alveolar capillary are around the alveoli - also inside the lung
Have a look at the wiki pages - within are some nice pictures and should give you the opinion. The windpipe (trachea) divides into the two main bronchi (left and right) and these subdivide into smaller bronchi and smaller and smaller ... until you bring to the bronchioles.
The bronchioles also divide and you eventually get to respiratory bronchioles and from these, the alveoli emerge. The capillary are wrapped around the alveoli.
they are inside the lungs... just tiny little things..
