Thekey difference在肝胆汁和胆囊胆汁之间是肝胆是由肝脏不断产生的胆汁来帮助食物消化,而胆囊胆胆是胆汁,胆汁储存并集中在胆囊中,直到需要在胆囊中需要食物的消化.
胆汁是肝脏产生的深绿色至淡黄色的液体,有助于脂质消化small intestine. In most vertebrates, it is produced continuously by the liver and normally stored in the gallbladder until the digestion of food. After eating, this stored bile (concentrated) comes into十二指肠to break down lipids in the food. Therefore, hepatic bile and gallbladder bile are two forms of bile in the body.

What is Hepatic Bile?
肝胆汁是由肝脏不断产生的胆汁,以帮助食物消化。It is a secretion of the liver. The composition of hepatic bile is water (97–98%), bile salts 0.7%, bilirubin 0.2%, fats 0.51%, and inorganic salts 200 meq/l. The fats of hepatic bile are composed of cholesterol, fatty acids, and lecithin. The two main pigments of hepatic bile are bilirubin and biliverdin. Bilirubin is orange to yellow in colour, and its oxidised form is biliverdin. Biliverdin is green in colour. When both are mixed together, they are responsible for the brown colour of feces. The liver produces about 400 to 800 millilitres of bile per day in adult human beings. The hepatic bile is alkaline on average (pH 7.50 to 8.05). Due to its alkaline nature, it has the function of neutralizing excess stomach acid of the chyme.
Bile acts as a surfactant to some extent, and it helps to emulsify the lipids in food. Bile salts are anions. They are hydrophilic on one side and hydrophobic on the other side. They aggregate around droplets of lipids and thus form micelles. The dispersion of fats of food into micelles provides a greatly increased surface area for the action of the enzyme pancreatic lipase that breaks down lipids more easily. Besides the digestive function, bile also serves also as the route of excretion for bilirubin, a by-product of recycled red blood cells. Bile also helps the absorption of fat-soluble vitamins such as the vitamins A, D, E, and K. Moreover, bile salts act as bactericides that kill bacteria in the food.
什么是胆囊胆汁?
胆囊胆胆是胆汁,胆汁被储存并集中在胆囊中,直到食物消化过程中需要它为止。胆囊充当肝脏生产的胆汁的储层。胆汁最初是从肝细胞分泌到常见的肝管道的。随着常见的肝管的下降,它与囊性管道相连,这使胆汁可以流入和流出胆囊以存放和释放。在这一点上,常见的肝管和囊性管结合在一起形成常见的胆管。普通的胆管将胆囊胆汁带入十二指肠,这是小肠的上部。
When a person eats, the gallbladder releases bile into the common bile duct, where it carries to the upper part of the small intestine (duodenum) to help break down fats in food. Sometimes, in pathological conditions, the cholesterol in gallbladder bile will occasionally accrete into lumps. Thus, it forms gallstones. Moreover, the longer a person does not eat, the bile in the gallbladder becomes more acidic. Usually, the gallbladder bile is acidic (6.80 to 7.65). Further, the phosphorus and protein concentration in gallbladder bile is specifically much higher.
What are the Similarities Between Hepatic Bile and Gallbladder Bile?
- They are two types of bile in the body.
- 两种类型的胆汁都分泌到普通的胆管中。
- Liver produces both types of bile.
- Both are carried into the upper part of the small intestine (duodenum) in the presence of food.
- 两种类型的功能都在促进通过乳化食物中脂肪的消化。
肝胆汁和胆囊胆汁有什么区别?
肝胆汁是由肝脏不断产生的胆汁,以帮助食物消化。另一方面,胆囊胆汁是胆汁,该胆汁被储存并集中在胆囊中,直到在食物消化过程中需要它。因此,这是肝胆汁和胆囊胆汁之间的关键区别。此外,肝胆汁本质上是碱性,而胆囊胆汁本质上是酸性的。
The following infographic summarizes the differences between hepatic bile and gallbladder bile in tabular form.
Summary – Hepatic Bile vs Gallbladder Bile
Bile is also called gall. It is a greenish-yellow secretion. There are two forms of bile in the body: hepatic bile and gallbladder bile. Hepatic bile is the bile that is produced continuously by the liver. On the other hand, gallbladder bile is the bile that is stored and concentrated in the gallbladder. Thus, this is the summary of the difference between hepatic bile and gallbladder bile.
