How is the circulatory system of insects different from mammals?

Answer 1

Yes, in fact you can see veins on the wings of some flying bugs, such as dragonflies. I also found out that Spiders don't have muscles; their blood circulates very swiftly from one leg to the other for them to run.

Answer 2

Insects rely on diffusion for transport for oxygen and since they are so small they don't need a complex circulatory system, they have an open one because nutrients are in direct contact to blood cells

Answer 3

The circulatory system in insects is open whereby they pump blood into a hemocoel after which blood will diffuse back into the circulatory system. In mammals, the circulatory system is closed and it involves blood moving through blood vessels to the different parts of the body.

Answer 4

Mammals and most vertebrates have a closed circulatory system in which the blood stays in the blood vessels and recirculates. In an open circulatory system the hemolymph is pumped out by the heart, but perfuses the entire body cavity.

Answer 5

ok from my understanding, the circulatory system is a transport system of the body. it transport lovely things such as: water, oxygen, carbon dioxide. It circulates hormones. hands out all the nutrients to the cell of the body (nutrient distribution). and maintains the bodys temperature. its made up of the heart, the blood (fluid which everything can be transported around in), blood vessels which all the blood can move aound in to get to the cells of the body to deliver things such as oxygen and take away things such as carbon dioxide.

the cardiovascular system is the heart and the viens.

So, therefore I'm gonna guess that the cardiovascular system is part of the circulatory system as they both got a heart, and viens as part of their systems. Yes so this is what i think. i actually needed an answer to this question but saw that it was answered... so i tried to help out and such. hope it helped. :)

Answer 6

In insects, the circulatory system is an open system where hemolymph (a mixture of blood and interstitial fluid) directly bathes the organs. In mammals, the circulatory system is a closed system with blood confined to vessels. Additionally, insects have a simple tube-like heart whereas mammals have a multi-chambered heart with separate systemic and pulmonary circuits.

Answer 7

The major difference among the circulatory systems of vertebrates involves the path of blood through the heart and the body as well as the number of chambers in the heart.

Answer 8

In cockroach,the circulatory system is of open type or lacunar type as the blood flows freely within the body cavity

Answer 9

Nothing
