Answer 2

hey mate here is the answer....✌️✌️

♦️open circulatory system:

➡️In open type the body cells and tissues are directly bathed in the blood pumped out of the heart as the blood flows In open spaces. hence, there is a direct contact and exchange of material between the blood and body cells. examples,
•Arthropods,
•non cephalopods molluscs,
•hemichordates,
•tunicates.

♦️closed circulatory system:

➡️In this system, the blood circulates through a series of the blood vessels of varying diameters i.e., arteries, veins and capillaries without ever coming in direct contact with body cells.
A series of these vessels maintain the continuous flow of blood.
The exchange of material between blood and body cells takes place in the capillaries. examples
•Annelids,
•cephalopod molluscs,
•chordates.
