Question

1) how are fats digested in our body where does this process take place ?

2) describe double circulation of blood in human being why is it necessary ?​

Answer 1

Answer:

Heya here's ur answer...

Lipids, or fat, go undigested in your digestive tract until they reach your small intestine, where they meet bile. Bile contains bile salts, which act as an emulsifier of lipids. This breaks the large fat droplets into smaller droplets that are then easier for the fat-digesting enzyme pancreatic lipase to digest.

2- During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.

Answer 2

Answer:

1) Fats are digested in the small intestine. The secretion of liver, called bile, breaks down the large globules of fat into smaller globules. ... The bile also makes the medium alkaline so that the pancreatic enzyme containing lipase further digest fats to form fatty acids.

2) During a single cycle blood goes twice in the heart which is known as double circulation. It is necessary in human being to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.
