Can You Keep Donating and Regrowing Your Liver?

The video explores the fascinating ability of the human liver to regrow after donation, highlighting that while the liver can regain its mass, it does not truly regenerate like some animals do. This process, known as compensatory hyperplasia, involves mature liver cells multiplying rather than dedifferentiating. Although the liver can regrow, repeat donations are not advisable due to surgical risks and complications in connecting regrown liver tissue to recipients. The video contrasts this with true regeneration seen in animals like salamanders, where cells revert to an embryonic state to regrow lost parts.

What is the main reason why the liver cannot be repeatedly donated and regrown like blood?

• The liver regrows too slowly.

• The liver regrows only in young individuals.

• The liver regrows but does not regenerate.

• The liver does not regrow at all.

How does liver regrowth in humans differ from true regeneration seen in some animals?

• Liver regrowth involves mature cells multiplying.

• Liver regrowth is faster than true regeneration.

• Liver cells dedifferentiate like in salamanders.

• Liver regrowth creates a completely new organ.

What is the term used to describe the liver's ability to regrow after a portion is removed?

• Organ duplication

• Cellular differentiation

• Compensatory hyperplasia

• True regeneration

Why is it not recommended to donate a portion of your liver more than once?

• The regrown liver has a different structure.

• The regrown liver is not functional.

• The regrown liver cannot be surgically removed.

• The regrown liver is too small.

What makes it difficult to connect a regrown liver chunk to a transplant recipient's blood vessels?

• The regrown liver chunk is too fragile.

• The regrown liver chunk lacks blood vessels.

• The regrown liver chunk has a different structure.

• The regrown liver chunk is too large.
