Arrange the structures in the following list in the order that blood will encounter as it flows from the heart back to the heart in the cardiovascular circuit. 1. venules
2. arterioles
3. capillaries
4. elastic arteries
5. medium veins
6. large veins
7. muscular arteries

The correct order is - 4.elastic arteries, 7.muscular arteries, 2. arterioles, 3. capillaries, 1. venules, 5. medium veins, 6.large veins

Explanation:

The cardiovascular circuit Or the pathway is the sequence of structures that takes oxygenated blood from the heart and deliver it to various parts of the body and than beings the deoxygenated blood back to the heart.

This cardiovascular circuits involves various types veins, Capillaries and arteries and heart. The correct order of the structures of order that blood will encounter as it flows from the heart back to the heart is -

4.elastic arteries, 7.muscular arteries, 2. arterioles, 3. capillaries, 1. venules, 5. medium veins, 6.large veins

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.

not only is it colder, it also becomes darker, less salty, and more dense.
