Question

Role of the water vascular system in Echinoderms is:
A. Respiration and Locomotion
B. Excretion and Locomotion
C. Capture and transport of food
D. Digestion and Respiration
E. Digestion and Excretion

• A. A and C Only
• B. B and C Only
• C. B, D and E Only
• D. A and B Only

Hint:

Water vascular system: Locomotion, Feeding, Respiration.

Answer 1

The Correct Option is A

The water vascular system is a unique hydraulic system found in echinoderms (starfish, sea urchins, etc.). It's primary functions are locomotion (via tube feet), food capture (also using tube feet), and respiration (gas exchange through tube feet and other structures). It plays a minor role in excretion, but its main roles are locomotion, feeding, and respiration.
