Not quite an infinite liver hack #shorts #throwbackthursday #science #scishow

The video explains liver regeneration, highlighting that a liver can regrow in about a year. If 30% of a liver is received from a donor, it can regenerate into a full-sized organ. The process involves liver cells receiving signals to grow and multiply. However, regrown livers differ in structure from original ones because they use mature cells instead of stem cells. While regrown livers function, they are not suitable for donation due to compatibility issues with original liver tissue.

How long does it typically take for a liver to regrow to its full size after a portion is removed?

• Three months

• One year

• Six months

• Two years

What triggers liver cells to start growing and multiplying during regeneration?

• An increase in oxygen levels

• The presence of new blood vessels

• A signal received by the cells

• A change in temperature

Why might a regenerated liver not have the same shape as the original?

• It uses different nutrients

• It grows faster

• It uses mature liver cells instead of stem cells

• It receives less blood supply

What type of cells are used to form the original liver?

• Stem cells

• Nerve cells

• Blood cells

• Mature liver cells

Why might a regrown liver not integrate well if donated?

• It has a different blood type

• It is too small

• It is made from mature liver cells

• It lacks necessary enzymes
