The large decrease in blood pressure as blood moves through the lungs may prevent efficient circulation through the rest of the body.

Name the organisms in which double circulation is found?
The double circulatory system of blood flow references two distinct and separate systems. This distinction is shared by most vertebrates to varying degrees to include amphibians, birds and mammals (including humans.)
Does an amphibian's heart pump out a mixture of oxygen-rich and oxygen-poor blood?
The amphibian's heart does pump out a mixture of oxygen-rich and oxygen-poor blood. They are vertebrates, and this is how vertebrates' circulatory systems work.
Do cows have two circulatory systems?
No. Cows, like humans, only have one circulatory system that is connected by only one heart. The systemic and pulmonary circuits of the circulatory system are such circuits that are interconnected within a mammal's body via the heart.
Why does cockroach not need a circulatory system?
Cockroaches do have circulatory systems, they are are open circulatory systems
What is the difference between a closed and open circulatory system?
We, as vertebrates, have a closed system in that our blood travels from the heart and back. Other organisms don't have such a system. Open circulatory systems allow all fluids in an organism to mix.
Example of animals with closed circulatory system?
Mammals including humans have closed circulatory systems, as do most vertebrates. Some invetebrates also have closed systems. Examples of open circulatory systems are most arthropods, including molluscs and crustaceans and insects.
What kind of circulatory system does a big horn sheep have?
Big horn sheep have a closed circulatory system like all other vertebrates. This means that the blood stays within the heart and blood vessels at all times. In open circulatory systems, blood is free within the animal's body cavity.
How does the circulatory system affect other body systems?
The circulatory system affects the other body systems because the circulatory system gives oxygen to the other system. Without the circulatory system the other systems would not work.
