arthropods transportation
Answers
Arthropods have what is referred to as an open circulatory system, where blood fills the body cavity of the animal. Humans have a closed circulatory system, where blood is moved around the body via vessels and arteries.
Inside of many animals exists an area of empty space called the coelom where you can find its organs. A coelom helps to give animals some rigidity and acts like a skeleton, giving the body a sort of structure. In arthropods, this coelom is much reduced, and divided into smaller areas around excretory and reproductive organs. Since they have skeletons, the leftover space is instead filled with blood which covers the other organs, keeping them bathed in blood. This cavity is referred to as a haemocoel, or blood cavity.
Answer:
Arthropods (animals in the phylum Arthropoda) have segmented bodies as well as an exoskeleton. They include animals such as insects, arachnids (spiders, scorpions, etc), and crustaceans. So, if arthropods' skeletons are on the outside, is what's on the inside different too? Sure is, but there are some things you'll find familiar. Let's take a look at their circulatory system.
