Answer 2

(i) Arthropods are animals with an 'open circulatory system'.  

(ii) Mammals are animals with a 'closed circulatory system'.  

Explanation:  

• Circulatory system is one of the most fundamental aspects of the normal functioning of living organisms. This system can be of 'two types' – closed and open.
• In an open system, the blood that flows through arteries and veins opens at certain areas of the body. In animals like arthropods, open circulation system exists.
• In a 'closed system', the blood remains within its channels and never comes in contact with the other areas of the body. Mammals have a closed system of circulation.
