Column 1 Column 2
Glycine , glucose small intestine , active absorption
As we have learned
Passive Transport -
Fatty acids and glycerol being insoluble, cannot be absorbed into the blood. They are first incorporated into small droplets called micelles which move into the intestinal mucosa. They are re-formed into very small protein coated fat globules called the chylomicrons which are transported into the lymph vessels (lacteals) in the villi.
- wherein
These lymph vessels ultimately release the absorbed substances into the blood stream
