अति संक्षिप्त उत्तर

The two kinds of circulatory systems in different animals are:

Open Circulatory System – Blood flows freely through open spaces or sinuses, rather than being confined to vessels. Example: Arthropods (insects) and mollusks.
Closed Circulatory System – Blood remains within a network of vessels (arteries, veins, and capillaries) throughout the body. Example: Vertebrates (humans, fish, amphibians) and annelids (earthworms).
