Answer 1

$\Huge\mathcal\purple {Ans}\mathcal\pink{wer}$

Open circulatory system: primarily found in invertebrates. Here, the blood flows freely through cavities since there are no vessels to conduct the blood.

Closed circulatory system: is found in vertebrates and a few invertebrates like earthworms. This system has vessels that conduct blood throughout the body.

Answer 2

Answer:

Open Circulatory System -

• The hemolymph directly bathes the organs and tissues
• The blood and interstitial fluid cannot be distinguished
• Present in molluscs and arthropods.
• Blood is pumped into the body cavity.
• Dorsal blood vessel present

Closed Circulatory System -

• The blood circulates within closed vessels
• Blood and interstitial fluid are distinct.
• Present in annelids and vertebrates.
• Blood is pumped through the vessels by the heart.
• Dorsal and ventral blood vessels present.
