The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

What makes stem cells so important in medical research
lara31 [8.8K]

Answer: Pretty much every aspect of them

Explanation:

Stem cells have unique regenerative abilities which can be used for treating diseases and disabilities (from diabetes to MS). They can also be used to graph skin from burns etc. The stem cell science world seems to leave so many options open for discoveries and they have less negative side effects in comparison to the chemical treatments available or soon to become available. Stem cells can heal rather than pharma therapies covering the ailment and leading to other issues.

Describe process in the human body in which there is evidence of the cell cycle at work
Alex Ar [27]
<span>I suspect this question should read "How long does a red blood cell live." A red blood cell lives for between 100 and 120 days. It takes 7 days for a new red blood cell to develop from stem cells. Stem cells are similar to base cells. They can also be seen as a general template from which specialized cells are made. Stem cells can be taken from a newborn baby's umbilical chord or extracted from an adult blood donor's blood.</span>
