A crayfish has an open circulatory system, which means that its blood, or hemolymph, flows freely through cavities and is not confined entirely to blood vessels. In contrast, humans have a closed circulatory system where blood circulates within a network of vessels, allowing for more efficient transport of oxygen and nutrients. Additionally, crayfish rely on gills for respiration, while humans use lungs. This fundamental difference impacts how each organism transports nutrients and oxygen throughout their bodies.
What else can I help you with?
Of the crayfish systems what two are the most unlike the humans systems?

The respiratory system of crayfish, which involves gills for gas exchange, differs from the human respiratory system that uses lungs.

Does a box elder maple tree have a circulatory system?
Yes, box elder maple trees have a circulatory system composed of xylem and phloem which transport water, nutrients, and sugars throughout the tree. Xylem carries water and minerals from the roots to the leaves, while phloem transports sugars produced through photosynthesis to other parts of the tree.
How does the dolphins circulatory system work?
Dolphins have a closed circulatory system much like ours containing arteries, vein's, blood vessels, and capillaries they have a heart a lot like ours but theirs has 5 chambers. They also have a slower heart beat because it give the blood more time to warm and circulate through their whole body. their body temp. averages a whole 940Ft. . Pretty cool huh.
