- peristalsis
- primary organ of digestion and absorption
- small intestine
- lymphatic capillary

- neutralizes acid in the duodenum
- bicarbonate
- accessory organ in digestion (3)
- gall bladder, pancreas, liver
- carrier-mediated transport of molecules across a cell membrane no energy required
- facilated diffusion
- filters blood of waste products and some excess nutrients
- kidneys
- transports water soluble digesive products to the liver
- portal vein
- transports water soluble digestive products after absorption
- lymphatic vessels
- product of mechanical digestion int he stomach
- chyme
- reabsorbs water and minerals
- large intestine
- release bile into the small intestine
- gall bladder
- circulation of bile between the small intestine and the liver
- enterohepatic
- releases stomach contenets into small intestine
- piloric sphincter
