There are many differences between cow's and human's circulatory systems. The cow system has to work around 4 stomachs for example.
the Egyptian gods had the heads of animal;the greek gods looked like humans.
Civil liberties are rights the law gives to citizens, whereas natural rights belong to all humans regardless of what the law says.
Salt is the only type of rock that humans can eat. Human digestive systems are not meant to break down other types of rocks.
There is no evidence or likelihood of a war between humans and aliens as there are no confirmed encounters with extraterrestrial life. Speculating on such scenarios is purely hypothetical at this point.
The purpose of a Turing test is to determine a machine's ability to exhibit intelligent behavior that is indistinguishable from that of a human. It tests whether a machine can successfully imitate a human to the extent that another human interacting with it cannot differentiate between the two.
Closed circulatory systems have blood that does not flow in defined blood vessels. Examples are insects and how their organs are bathed continually in "blood". Open circulatory systems have blood that flows in vessels. Humans have this system as blood flows in veins, arteries and capillaries.

A perch heart has two chambers and a humans has four cambers
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
Both are close circulatory system.
closed. Open circulatory systems are common in athropods, such as scorpions and insects, but not of mammals. They are when the body lacks blood vessels but has blood throughout the entire cavity of the body. Mammals have closed circulatory systems, as they contain blood vessels.

A crayfish has an open circulatory system while humans have a closed circulatory system. "Closed" means that we have true blood vessels that carry blood to and from the heart. "Open" means that the organs are simply bathed in blood that freely circulates around the body. Sometimes the heart can move the "blood" by creating pressure waves in the fluid.
Humans eat and plants use photosynthesis Theres one
digestive and circulatory
Some dont have any at all but most have closed cirrculatory systems.
Segmented worms have closed circulatory systems like humans. This means that blood is carried throughout the body in vessels: arteries, veins, and capillaries. So, like humans a segmented worm's circulatory system just carries blood through vessels.
