Yes, they do reflect a high degree of internal organization with organ systems for circulatory, reproductive, digestive and neurological functions to support a sensory array including (in most) vision and (in many) a highly attenuated chemical sense.
No. Arthropods have "exoskeletons", shells outside their bodies that contain and protect their internal organs.
Muscular, nervous, skeletal, digestive, and cardiovascular are all organ systems which are made of organs i.e. muscular system is made of all the organs known as muscels. Another example is the skeletal system. The parts that form it are called bones, and are an example of organs.
Yes. Arthropods have body cavities (coelomates); their main internal cavity is a hemocoel, which accommodates their internal organs and through which their blood circulates - they have open circulatory systems. Arthopods come from a lineage of animals that have a coelom, a membrane-lined cavity between the gut and the body wall that accommodates the internal organs. The coelom of the arthropod is reduced to small areas around the reproductive and excretory systems. Visit http://smackers0609.blogspot.com/Yes.

Arthropods have segmented bodies, an exoskeleton made from chitin, and joint appendages. On arthropods you will observe an internal body cavity called a hemocoel to contain the internal organs which are bathed in hemolymph.
The skin is the largest organ, but of the two organs quoted in the question, the liver is larger than the heart.
Yes, organ systems are made up of multiple organs that work together to perform specific functions in the body. Therefore, organ systems are usually bigger in size and complexity compared to individual organs.
It is not an organ as it is made of many organs and systems.
Yes, in simple terms. Tissue makes up organs, which make up organ systems. organ systems>organs>tissues>cells
