It plays a role in mechanical digestion of lipids due to bile.
Liver
Approximately _____________ of bile is produced everyday.
500ml to 1000 ml
What the bile does?
Bile breaks down large fat globules
into smaller droplets of fat.
Bile entering the bile ducts eventually leaves the liver via ____________ the to travel
towards the __________ .
common Hepatic duct
duodenum
It is a yellow-green alkaline solution composed of bile salts, bile pigments, cholesterol, neutral fats, phospholipids, and electrolytes.
Bile
___________ Primarily composed of cholic acid, which is a derivative of cholesterol.They emulsify fats; they facilitate fat and cholesterol absorption.
Bile salts
Bile salts get reabsorbed by the ___________ then return to the ______ and get re-secreted in newly formed bile.
distal small intestine
liver
What are examples of substances being metabolized by the liver?
Protein and fat
What does the liver perform by maintaining normal blood glucose levels?
complex chemical reactions.
Protein compounds are synthesized in liver. These proteins are then released into the blood and are called __________ or _________ (help in blood clotting/maintaining normal blood levels).
blood proteins
plasma proteins
__________ detoxify poisonous substances in blood such as bacteria products and certain drugs.
Liver cells
_________ - The liver can store many substances for later use like iron and vitamins A and D.
Storage
After the liver detoxified chemicals, including alcohol, beer, wine and drugs. how does the body eliminate the detoxified chemicals?
By urination
The converted substances from the liver is then brought to what organ:
The kidneys
True or False. The liver does the following:
A.Filters out waste produced by the body.
B.Make clotting factors that stop the bleeding when you cut yourself.
C.And literally hundreds of other functions.
True
____________ is a thin walled, green muscular sac approximately 10 cm long. It stores bile that is not immediately needed for digestion and concentrates it by absorbing some of its water and ions.
Gallbladder
How concentrated is the bile that is being released from the gallbladder?
10x more concentrated than usually.
Describe the mucosa lining of the Gallbladder:
The mucosa lining of the gallbladder resembles rugae in stomach. It can fold in on itself when little or no bile is in it. When it is filled, the mucosa can expand.
What happens when the gallbladder’s muscular wall contracts?
bile is expelled into its duct (cystic duct) then flows into the bile duct.
