I WONDER - How Is Our Blood Cleaned?

The liver is an essential organ with a dual blood supply from the hepatic artery and portal vein. It processes nutrients and vitamins from the food we eat, converting them into usable forms for the body. The liver also plays a crucial role in cleansing the blood by separating waste from healthy blood, which is then excreted from the body. This process ensures that the blood remains clean and nutrient-rich, highlighting the liver's vital function in maintaining overall health.

What is the role of the hepatic artery in the liver's blood supply?

• It transports waste products to the intestine.

• It supplies oxygenated blood from the body's general circulation.

• It delivers deoxygenated blood from the small intestine.

• It carries nutrients directly to the liver cells.

Which blood vessel delivers nutrient-rich blood to the liver?

• Renal artery

• Coronary artery

• Portal vein

• Hepatic artery

How does the liver process nutrients from the blood?

• By converting them into waste products

• By storing them indefinitely

• By sending them back to the small intestine

• By transforming them into usable forms for the body

What happens to waste products separated by the liver?

• They are converted into nutrients.

• They are released into the bloodstream.

• They are stored in the liver permanently.

• They are sent back to the intestine for excretion.

What is the primary function of the liver in blood cleansing?

• To remove harmful substances and release clean blood

• To produce red blood cells
