make the connection: your heart is dependent on oxygen from your respiratory system, and it is delivered by the(1 point)
lidiya [134]

Oxygen from the respiratory system is delivered by the circulatory system.

<h3>What is the relationship between respiratory and circulatory system?</h3>

The respiratory system is responsible for delivering oxygen to the circulatory system that is made up of blood vessels which carry blood to the heart and then all cells of our body. Arteries carry blood that is loaded with oxygen from the heart to all cells whereas veins carry deoxygenated blood back to the heart and then to the lungs for disposing carbondioxide. The circulatory system carries oxygen and nutrients to the cells, and removes waste products such as carbon dioxide.

So we can conclude that Oxygen from the respiratory system is delivered by the circulatory system.

The accumulation of ____________allowed organisms to grow larger.
FinnZ [79.3K]

       The right answer to this question is option A. O2 in the atmosphere.

       The main reason why it's a true that organisms would grow larger than we have today with more oxygen available is pretty simple to understand, their respiratory systems were smaller than we have today, and even though it was a small one, it was enough because of the higher presence and concentration of O2 in the atmosphere.

        Some studies were held nowadays to check this possibility, to see if the O2 was the real main reason for this, and the animals used in it really grew bigger than usual, so by that, they confirmed their hypothesis by testing it.
