In our ayurveda location of grahani is between aamashaya and  pkwashaya. So in ayurveda mahashrotas (G.I.T.) IS divided in mainly 3 parts i.e.- aamasaya,grahani (pachyamanashaya),pkwashaya. Also in modern literature  there are three parts of gut foregut,mid gut,hinf gut,from which all G.I.T. organs develop (oesopjagus,stomach,duodenum, small intestine ,large intestine develope). Generally we correlate grahani with only duodenum but it is not true ,because  grahani is a broad term .if correlate with modern science it extend from opening of pancreatic duct to the junction of  right 2/3 and left 1/3 of transeverse colon.

 so the part of GIT where the food from stomach are entering the second part of duodenum and mix with the  pancreatic juice (containing digestive enzyme)  to where last absoption of food take place should know as grahani. Because

after  right 2/3 part of transverse colon there is no digestion or absorption of food take place so after that part rest of colon and rectum and anal canal up to pectinate line should be called as pkwashaya.

so above description it is clear that the grahani is  broad term containing the part develop by mid gut.because the grahani is part of GIT where food digestion,and absorption take place.
