No
The gills would not function well because they need to get oxygen flowing through them to make the creature able to breathe.
we need oxygen to function because without oxygen we would suffocate to death. without oxygen we wouldn't exist right now.
you would not be able to sents the nutrients and oxygen to your cells and you would be unable to live.
The heart, blood vessels, and lungs work together to circulate oxygen-rich blood throughout the body. The heart pumps blood, the blood vessels carry it to different tissues, and the lungs exchange oxygen and carbon dioxide to maintain proper oxygen levels in the blood.
The function of blood in circulatory is to bring oxygen to the cells around the body. Without blood cells would not be able to get oxygen.
Blood is the liquid that carries out circulation in the human body. It is pumped by the heart through blood vessels to deliver oxygen and nutrients to cells and remove waste products.
It can, but only indirectly- that is, from not being able to get oxygen to the brain successfully. That would only happen in severe forms of the disease, where red blood cells clog even medium-sized blood vessels. Someone with that would show all the signs of oxygen deprivation, such as decreased cognitive function and irritability.
Oxygen and carbon dioxide are exchanged across the lining of a frog's mouth. Oxygen is absorbed from the air into the blood vessels, while carbon dioxide is released into the air from the blood vessels.
Like all cells in our bodies, the cells in our eyes require oxygen and nutrients, and they need to eliminate waste. For many animals, transporting oxygen, nutrients, and cellular wastes is done using the blood vessels. So it only makes sense that we would have blood vessels in our eyes.
One of the ways to do this would be using Electrolysis.
The coronary blood supply is the arteries which supply the heart itself; in order for the heart to function it needs a good supply of oxygen just the same as any other organ/muscle. Without the coronary blood supply the heart would not be able to pump blood around the body, a disruption in this blood supply would cause a heart attack.
Earthworms have five main blood vessels within their bodies. These vessels function in a similar function as would hearts in other animals.
