9. Compare and contrast the circulatory systems of animals using the table below: Direct Exchange Open Circulatory System Closed Circulatory System a. What animals have this type of circulation? b. What is the transport fluid? c. What are the components of each system? d. What are the advantages of each systems? e. What are the disadvantages of each system?

Vertebrates, such as humans, have a(n) pathway. pulmonary circulatory lungs The heart pumps blood to the tissues through the circuit. systemic terrestrial The heart pumps blood to the lungs through the circuit. gills one-circuit This type of circulatory pathway is seen in organisms that utilize to breathe air. two-circuit

6. Which of the following will lead to local vasodilation in a systemic blood vessel? a. High endotheliumb. Low CO2 c. Low oxygen d. High PH

In the vertebrate circulatory system, the large arteries (i.e. the aorta and arteries collectively)... A. are the site of highest blood vessel total cross-sectional area B. have the highest total blood flow C. are the site of exchange between the blood and the tissues D. have the highest blood pressure E. All of the above

Which circulatory system do you think is most efficient at delivering oxygen rich blood to the tissues of an animal? O Gastrovascular system seen in most Cnidarians O Closed circulatory system seen in vertebrates O Open circulatory system seen in many arthropods

Insects have a blood system most similar to: O a. Nematodes. O b. Snails (Molluscs). O c. Annelids. O d. Flatworms (Platyhelminthes). O e. Chordates.

D3.

Refer to the figure below I. II II IV Reference: Ref 25-7 This circulatory plan belongs to which group of animals? Select one: O a. Fish O b. Invertebrates O c. Decapod crustaceans Od. Cephalopod molluscs

What are the important differences in the overall metabolic needs of a fish and a turtle and the ability of their circulatory systems to meet those needs? Select all that apply. Fish are less able to meet their metabolic needs than are turtles.  Fish have a two-chamber heart (one atrium and one ventricle) and turtles have a three-chambered heart (two atria and one ventricle). Turtles are endothermic and fish are ectothermic  Blood flows directly to other organs after being oxygenated in turtles, but return to the heart after being oxygenated in fish.  Turtles have a double,-circuit circulatory system whereas fish have a single circulatory system.
