Step 1
In an open circulatory system, the blood is not always contained within blood vessels. Instead, it flows freely through cavities in the body, bathing the organs directly. This system is found in many invertebrates, such as arthropods and mollusks. Show more…

Why are open circulatory systems advantageous to some animals? a. They use less metabolic energy. b. They help the animal move faster. c. They do not need a heart. d. They help large insects develop.
A circulatory system is the main method for transporting gases and nutrients throughout the body. Explain what happens in a closed circulatory system and compare a closed circulatory system to an open closed circulatory system. a. Blood in closed circulatory system is present inside blood vessels and circulates unidirectional from the heart, around the systemic circulatory route, then returns to the heart. It is less controlled and structured than an open circulatory system, but nutrients and waste products are transported more efficiently. b. Blood in closed circulatory system is not enclosed in blood vessels, but is pumped into a hemocoel, which circulates around the organs, then reenters the heart through ostia. It is more structured, controlled, and nutrients and waste products are transported more efficiently. c. Blood in closed circulatory system is not enclosed in blood vessels, but is pumped into a hemocoel, which circulates around the organs, then reenters the heart through ostia. It is less controlled and structured than an open circulatory system, but nutrients and waste products are transported more efficiently. d. Blood in a closed circulatory system is present inside blood vessels, circulates unidirectional from heart around the systemic circulatory route, and then returns to the heart. It is more structured, controlled, and nutrients and waste products are transported more efficiently than in open circulatory system.
