MYP Biology 9.3 3D Tissue and Organ Printing Questionbank

The use of a patient's own cells in 3D organ printing is primarily intended to eliminate the long-term medical need for __________.

In thick 3D-printed structures that lack an internal transport system, what is the primary cause of cell death in the central regions?

They are larger and easier for the printer nozzle to deposit

They can differentiate into the specific specialized cells needed for the tissue

They do not require a scaffold to maintain their structure

They are the only cells that can survive the printing process

It prevents the accumulation of metabolic byproducts that could reach toxic levels

It provides the cells with a source of structural protein for the scaffold

It helps to maintain a high concentration of carbon dioxide for cellular respiration

It ensures that the bioink remains at a low enough pressure to prevent cell damage

True

False

bioreactors

scaffold materials

nutrient-rich bioink

immunosuppressant drugs

The rapid multiplication of cells causing overcrowding in the center

The lack of light reaching the interior of the tissue

The chemical reaction between the bioink and the printer nozzle

The accumulation of toxic metabolic waste products that cannot be removed
