chyle the milky fluid taken up by the lacteals from the intestine during digestion, consisting of lymph and triglyceride fat (chylomicrons) in a stable emulsion, and conveyed by the thoracic duct to empty into the venous system.
Because of the ruined state of the interior, it is impractical to use the Colosseum to host large events; only a few hundred spectators can be accommodated in temporary seating. However, much larger concerts have been held just outside, using the Colosseum as a backdrop.
The Colosseum had a total spectator capacity of 45,000-55,000. The Amphitheater is built of travertine outside, and of tufa and brick in the interior. The main pedestals were built of marble blocks weighing 5 metric tons (11,000 pounds.) Initially the huge marble blocks were held together by metal-pins.
