According to my anatomy and physiology of farm animals class, regions and systems are two different things. Often mistakenly used.
Regions are all the components in a section of an animal- the blood vessels, tissues, nerves, cells, bones, etc. IN THAT SECTION (imagine dividing the animal into parts).
Systems overlap regions and refer to the networksinside the body as a whole- skeletal, muscular, integumentary, immune, nervous, digestive, cardiovascular, respiratory, sensory, endocrine, urinary, reproductive, etc.
If your professor asks you to list the components in the cervical region of a canine, you would list all the above components in said region. If your professor asks you which system bones and joints belong to (for example), you would say the [skeletal] system. Make sense?
By cutting the body of the animal(dead) or by cutting planes of the required body.
How can you identify the body symmetry of an animal
By cutting the body of the animal(dead) or by cutting planes of the required body.
The answer is because the body systems are different from eachother you tend to do different things from the other person/animal
The body characteristics that have evolved to enable an animal to live in polar regions.
An arthropod, such as an insect or a crab, typically has two distinct body regions: the head and the thorax-abdomen region. These distinct body regions allow for specialization of different functions within the organism.
Every animal is different
It doesn't. This is a myth. The platypus is not a mixture of any other animal.

Animal cells are found throughout an animal's body, as they make up the different tissues and organs. These cells are organized into tissues, which work together to perform specific functions within the body.
Epithilial Tissue Lines animal's body Cavity, they can be further subdivided into different types of Epithelial Tissue, depending on what they line
Animals support their bodies in different ways. In most cases, animals will use their limbs to support their entire body.
