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.

Is circulation in earthworms open or closed?
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.

What is special about earthworms reproductive system?
Earthworms have a unique reproductive system that is hermaphroditic, meaning each individual possesses both male and female reproductive organs.

They produce a cocoon from a special gland, which contains the fertilized eggs and serves as a protective environment for the developing young. This reproductive strategy enhances their ability to reproduce in diverse environments.
What are the examples of closed circulatory system?
