earthworms have a closed circulatory system
Earthworms do not have hearts in the traditional sense; instead, they possess a series of muscular structures called aortic arches. These aortic arches function similarly to hearts by contracting to pump blood throughout the earthworm's closed circulatory system. The blood is circulated through vessels, delivering nutrients and oxygen to the worm's tissues.
Earthworms
well Earthworms have closed circulatory system so hopefully that answers your question
closed circulatory system
an open circulatory system
Earthworms have a closed circulatory system. This means that their blood is contained within vessels as it circulates throughout the body, allowing for more efficient transport of nutrients and oxygen. The blood is pumped by a series of muscular structures called aortic arches, which act like hearts. This system enables earthworms to maintain a more regulated flow of blood compared to open circulatory systems.
Circulatory.
yes, they have a complete digestive system with organs and a circulatory system with organs.
