Question

A liver performs multiple functions and is also one of the heaviest organs in the body, second only to the brain. So, when an artificial liver is being produced, recreating what physical property of the liver poses a challenge?

(a) mass of the cells

(b) volume of the cells

(c) density of the cells

(d) size of the cells

Answer 1

Correct choice is (c) density of the cells

The explanation is: A liver performs various functions like destroying toxic substances, producing bile, a breakdown of the old and decaying blood cells etc. However, for this to happen, the liver needs a large number of cells but in a small area. Thus, this increases the density of the liver. So, one of the biggest problems is recreating the density of the cells.
