Sorry if this is wrong but a closed circulatory system is blood that is contained inside blood vessels, circulating unidirectionally (in one direction) from the heart around the systemic circulatory route, then returning to the heart again.

If the circulatory system failed what would happen to the heart rate?
Gelneren [198K]
The heart rate would decrease because there is less oxygen being supplied to the cells for cellular respiration, and also your muscles won't get the blood it needs. Blood also contains oxygen and glucose which cells need to convert food to energy and to survive, so if the cells don't get blood they will die which will eventually kill the organism

<h3>What does natural selection mean?</h3>

According to the evolution theory, natural selection is a slow process of differential survival of the fittest organisms in a given environment.

Conversely, genetic engineering refers to the molecular biology techniques used in the laboratory to produce organisms expressing desired phenotypes.

In conclusion, genetic engineering is based on human molecular biology techniques, whereas natural selection refers to differential survival and reproduction in nature.
