Question

hii guys , i hope u safe difference between open circulatory and closed circulatory system plzzz fast friend

Answer 1

Some points about open circulatory system are as follows-

• Speed of the blood in this is less.
• Blood pressure is also less in the open circulatory system.
• In it each and every tissue is in the direct contact of the circulatory fluid.
• Through large vessels blood is passes which is pumped by the heart which is known as sinuses.
• It is very less efficient.
• Examples- Arthropoda, Mollusca (except Cephalopoda) etc.

Some points about closed circulatory system are as follows-

• Speed of the blood more in this.
• Blood pressure is more compared to open circulatory system.
• Through a closed network of the blood vessels blood is pumped and circulated by the heart.
• It is more efficient.
• Each and every tissue is not in the direct contact with the blood.
• Examples- Annelida, All chordates, Cephalopoda etc.

Answer 2

Answer:

Open and closed circulatory systems are involved in the distribution of materials throughout the animal body. An open circulatory system lacks a vascular system and hence, the circulatory fluid directly bathes tissues and organs inside the body cavity. In a closed circulatory system, blood flows through a vascular system.
