Question
What are the two types of circulatory pathways?
Solution
The two types of circulatory pathways are:
i. Open circulatory pathway - In this type the blood
pumped by the heart passes through large vessels into open spaces or body cavities called sinuses. It is found in arthropods and molluscs
ii. Closed circulatory pathway - In this type the blood pumped by the heart is always circulated through a closed network of blood vessels. Annelids and chordates have a closed circulatory system.
