Molecules that are not soluble in water are fats and non-polar molecules . During their digestion and absorption in the small snall intestine, fats are packaged into hydrophilic form.

Explanation:

This explains the digestion of fats in the small intestine. This takes place in the illeum.( the longest part of 3.5 m) Bile  salts from the liver, emulsified  these fats, covering then with layers,while  enzymatic action  by  lipase, from the pancreases,   completes the process.

These fatty  substance formed  are called Micelles.In  the intestinal cells, the micelles are covered by protein and lipids to aid transport in water medium of the intestine.A this sage they are called (lipoprotein).

They are absorbed in the lacteal- the lymphatic capillaries , unlike protein and CHO which are absorbed   directly in the blood stream.I

 They are   finally absorbed  into the blood stream via the lymphatic vessels.

air enters through the nose, moves through the nasal cavity, the pharynx, the larynx, enters the trachea, moves through the bronchi andbronchioles till the alveoli.
