Which one of the following options is incorrect about human digestive system?
Liver receives bile juices secreted by gall bladder.
In the human digestive system, the small intestine is highly coiled and its inner walls are lined with thousands of finger-like projections called villi that increase the surface area for absorption, so this statement is true.
Bile juice is actually secreted by the liver, and the gall bladder only stores and concentrates this bile before releasing it into the small intestine during digestion, so the statement that the liver receives bile from the gall bladder reverses their actual roles and is incorrect.
The large intestine is indeed wider in diameter but shorter in length than the small intestine, so this statement is true.
Undigested and unabsorbed waste material is collected in the rectum and eliminated from the body through the anus, so this statement is true.
Hence, the incorrect statement is that the liver receives bile juice secreted by the gall bladder, since it is actually the liver that secretes bile and the gall bladder that stores it.
