Answer 2

Closed circulatory system contains tube and channels for passive of blood. Here there is a defined path for sending and receiving deoxygenated and oxygenated blood respectively
But in open circulatory system there are no tubes and channels so it is not sop efficient in passage and purification of blood.
That is why closed circulatory system is efficient than open circulatory system.
