Is the pigeon bold?

The pigeon is no courage.The main function of gallbladder is to secrete bile to help digestion, and pigeons mainly eat some foods without fat or less fat.Therefore, after evolution, their gallbladder gradually degenerate to reduce the burden during flight.However, there are also many plant fruits that contain fat, such as peanuts, corn, etc., and pigeons can also digest.This is because the liver of the pigeon can secrete bile into the pigeon's intestine to help digest fat.

1. Is the pigeon courage?

There is no courage.This is because the existence of gallbladder is mainly to secrete bile to digest fat, and pigeons mainly eat some plant foods, and they rarely digest fat.Therefore, after a long period of evolution, in order to reduce the burden on flight, the gallbladder of the pigeon gradually degraded.However, the fruits of some plants also contain fat, such as peanuts, but pigeons can be eaten.This is because, although the gallbladder of the pigeon is degraded, the liver of the pigeon can directly secrete bile into the intestine, so even if the fruit of the plant contains oil, the pigeons can be eaten.But don't eat too much, avoid too much burden on its liver.

2. What is the use of pigeon liver

(1) Metabolic function: The nutrients intake of pigeons, such as carbohydrates, protein, fat, etc., are decomposed by the liver, and then synthesize the nutrients it themselves, thinking that it provides energy itself.

(2) Detoxic function: All substances entering the pigeons need to be decomposed in the liver, including toxic substances produced by toxic substances and metabolism from the outside world.

(3) Smile bile: The liver cells of the pigeon will be made and secrete bile to help the gastrointestinal digestion and absorb fat.

(4) Coagulation and hemostasis: Cell responsible for coagulation are synthesized by liver cells.

(5) Immune: The liver has a mesh endothelial cell phagocytosis system, which can protect the liver by devouring harmful substances.
