What is the function of the closed circulatory system?
Options
- ATo regulate fluid flow precisely
- BTo absorb fats
- CTo carry lymph
- DTo exchange nutrients and gases
Correct answer
A. To regulate fluid flow precisely
Step-by-step solution
The circulatory patterns are of two types – open or closed. Open circulatory system is present in arthropods and molluscs in which blood pumped by the heart passes through large vessels into open spaces or body cavities called sinuses. Annelids and chordates have a closed circulatory system in which the blood pumped by the heart is always circulated through a closed network of blood vessels. This pattern is considered to be more advantageous as the flow of fluid can be more precisely regulated.
