Solution

Arthropods:
Arthropods are coelomates and have an open circulatory system.
Blood consequently circulates within the cavity.
The cavity is known as a haemocoel, and the blood that runs through it is known as haemolymph.
Through an opening known as the ostium, blood enters the heart.
All of the organs within the body cavity acquire nutrition from the blood that the heart pumps into the body cavity.
Final answer: The open circulatory system is found in arthropods where the coelomic cavity is filled with blood.
