The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.

How are stem cells used to repair the central nervous system
Tju [1.3M]
Hello,

Your answer would be:

Stem cells come from an early embryo and these are divided into three types which are Embryonic stem cells, tissue stem cells and Induced pluripotent stem cells, or ‘reprogrammed’ stem cells. Currently, stem cells are being used in the laboratory for clinical trials to provide new therapies and other possible ways for treatments for certain diseases. Hope this answer helps.

Here’s the answer to your question would be:

They replace old neurons with new ones.

Here’s a article from the internet:


“Today, most treatments for damage to the brain or spinal cord aim to relieve symptoms and limit further damage. But recent research into the regeneration mechanisms of the central nervous system, including the discovery of stem cells in the adult brain that can give rise to new neurons and neural support cells, has raised hopes that researchers can find ways to actually repair central nervous system damage. Research on stem cells in nervous system disorders is one of the few areas in which there is evidence that cell-replacement therapy can restore lost function.”

Plz mark me brainliest!

Hope this helps! They also treat disorders
