The enterohepatic circulation refers to the circular flow of bile through the small intestine and liver. Which of the following statement(s) concerning the absorption of bile salts is/are correct?
A.	The enterohepatic circulation is highly efficient with 80% to 90% of secreted bile salts reabsorbed and returned to the liver through the portal circulation
B.	The reabsorption of bile is entirely an active process
C.	The small amount of bile escaping in the colon is deconjugated by bacteria, promoting lipid solubility and passive colonic absorption
D.	Ileal resection results in presenting high concentrations of bile salts to the colon which promotes diarrhea by bacterial overgrowth
