Bile is a thick alkaline fluid that is secreted by
the liver and stored in the gall
Bile is ejected into the duodenum
via the common
bile duct, that is - it does not flow continuousl,y but is released
Bile may vary in colour (e.g. yellow, green, brown) according to the
proportions of bile pigments. Leithin, cholesterol and bile salts are
also present in bile.
What it does:
Bile salts help to emulsify fats
in the duodenum
so that they can be more readily broken-down by pancreatic lipase
acids and glycerol.
Bile salts also form compounds with fatty acids.
Bile also helps to stimulate peristalsis
in the duodenum.
