Functions of the Liver

The video explains the liver's role in regulating nutrient levels by intercepting blood from the gut. It details the liver's dual blood supply through the hepatic artery and portal vein. The liver processes excess glucose into glycogen, manages amino acids for energy, and handles nitrogenous waste. Lipids are processed and distributed, while excess cholesterol is converted into bile salts. These processes ensure nutrients are stored, used, or removed as needed.

What is the primary function of the liver in relation to blood from the gut?

• To filter out toxins

• To regulate nutrient levels

• To produce red blood cells

• To store vitamins

Which two blood vessels supply blood to the liver?

• Hepatic artery and hepatic portal vein

• Hepatic portal vein and aorta

• Hepatic artery and renal vein

• Aorta and renal artery

What happens to excess glucose in the liver?

• It is converted into amino acids

• It is stored as glycogen

• It is excreted as waste

• It is converted into lipids

How does the liver utilize excess amino acids?

• They are excreted as urea

• They are used as energy sources

• They are converted into glucose

• They are stored as proteins

What is the process of breaking down amino acids in the liver called?

• Glycogenesis

• Nitrogenous waste processing

• Gluconeogenesis

• Lipolysis

What happens to triglycerides in the liver?

• They are converted into glucose

• They are stored as glycogen

• They are transported through blood plasma

• They are excreted as waste

How does the liver handle excess cholesterol?

• It is excreted directly

• It is used to produce hormones

• It is stored as glycogen

• It is converted into bile salts

What is the role of bile salts in the body?

• To aid in digestion

• To store energy

• To transport oxygen

• To produce hormones

Which of the following is NOT a function of the liver?

• Producing insulin

• Regulating blood sugar levels

• Producing bile

• Storing vitamins
