What is sweat composed of and what is its function?
Sweat is a mixture of water, salt, and minerals. Its function is to cool us down when it is hot.
Where are sweat glands most commonly found?
Sweat glands produce sweat and are found all over the skin, but are more frequent in armpits, hands, and feet.

Bile is a digestive juice produced by the liver.
What is chyme and where does it go after leaving the stomach?
Chyme is the partly fluid and partly solid mass of incompletely digested food that passes from the stomach into the first part of the small intestine.
What are gastric juices and what do they do?
