starting in the lumen of the small intestine, put the following steps of fat absorption in order

fat droplets are covered in bile salts.colipase and the lipase breakdown fats into micelles. Monoglycerides and fatty acids enter cell by diffusion. Energy used to transport cholesterol, and bile is recycled. A triglyceride cholesterol, and protein form chylomicrons. Fat packet is sent into a lymph lacteals.
