minimizes diffusion distance(bulk flow)
transports substances in the fluid:
gases
nutrients
wastes

Question 15

open circulatory system
An open circulatory system, found in arthropods, pumps blood into a cavity called a hemocoel where it surrounds the organs and then returns to the heart(s) through ostia (openings).
close circulatory system
A closed circulatory system, found in all vertebrates and some invertebrates, circulates blood unidirectionally from the heart, around the body, and back to the heart.

Question 16

Warm-blooded animals require the more-efficient system of four chambers that has the oxygenated blood completely separated from the deoxygenated blood.

Answer 16

Warm-blooded animals require the more-efficient system of four chambers that has the oxygenated blood completely separated from the deoxygenated blood.

Question 17

Vertebrate cardiovascular system
•3 blood vessel types 
•Arteries (away from heart) 
•Capillaries
•Veins (towards heart) 
•Blood flow in one direction 
•Heart pumps blood
