A student observes a blood vessel in a grasshopper. For this reason, the student claims that a grasshopper has a closed circulatory system. Evaluate the students claim.

The student's claim is wrong

Explanation:

Grasshoppers like most insects, have an open circulatory system.

A closed circulatory system is that type of circulatory system that can be seen in mammals, reptiles, birds and other higher organisms. it involves the movement of bodily fluid throughout the body through the use of vessels.

A grasshopper has an open circulatory system because its "blood" is not pumped in vessels, but rather, fills all the cavities of its body. this is usually common for less complex animals with low metabolism rates
