Compare closed and opened circulatory system

Answer»

The blood in a closed circulatory system is enclosed in blood vessels as it moves around the body of the organisms. The blood is pumped from the heart and stays confined within these blood vessels.
In open circulatory system, the blood is pumped from the heart into body CAVITIES and surrounds the body tissues. The blood is pumped into an hemocoel and treturns to the circulatory system by passing through cells.
                                              or Closed circulatory system
Vertebrates, and a few invertebrates, have a closed circulatory system. Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body cavities.
Open circulatory system
The open circulatory system is COMMON to molluscs and arthropods. Open circulatory systems (evolved in crustaceans, insects, MOLLUSKS and other invertebrates) pump blood into a hemocoel with the blood diffusing BACK to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.

we all know that the chemical formula of water is H2 + O2 = H2O... but why we can manufacture water while knowing the the chemical formula of water....????

Answer»

Hi...


THEORETICALLY, this is possible, but it would be an extremely dangerous process, too.

To CREATE WATER, oxygen and HYDROGEN atoms must be present.

Mixing them together doesn't help; you're still left with just separate hydrogen and oxygen atoms..


A great process is required to combine the 2 molecules present and maybe that technology is not developed that may bear the energy released during the process
