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.
The ancient Greeks were generally shorter in height compared to modern humans. This difference is mainly due to factors such as nutrition, healthcare, and genetics.
The ancient Egyptians were generally shorter in stature compared to modern humans. This difference in height is attributed to factors such as nutrition, health, and living conditions.
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.

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.
Humans eat and plants use photosynthesis Theres one

digestive and circulatory
Some dont have any at all but most have closed cirrculatory systems.
The main difference between the circulatory systems of humans and giraffes is the length of their blood vessels. Giraffes have very long necks, so their heart must pump blood with enough force to reach their brain. This results in higher blood pressure and a larger heart compared to humans. Additionally, giraffes have specialized valves in their neck to prevent blood from rushing to their brain when they lower their heads to drink.
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.
Unicellular: Exchanges occur directly with enviroment Multicellular: Diffusion is not possible unless diffusion across body surface. Transporting substances over long distance in animals.
