- Two distinctly different styles of circulatory systems have evolved among animals: open and closed. What is “open” about an open cir-culatory system?

A. In mammals, the blood pressure in the aorta is higher than the pressure in the pulmonary artery. B. In fishes, oxygenated blood from the gills returns directly to the heart through the left atrium. C. In birds, deoxygenated blood leaves the heart through the pulmonary artery. D. In reptiles, the blood in the pulmonary artery has a lower oxygen content than the blood in the aorta. E. In amphibians, deoxygenated blood enters the heart through the right atrium.arrow_forward

A. One or more muscular chamber hearts drive blood through the closed circulatory system of the grasshopper. B. The grasshopper has an open circulatory system with a heart that is a peristaltic vessel. C. Because the grasshopper has an open circulatory system, the maximum hemolymph pressures that can be achieved are relatively low, which limits the maximum metabolic rate that can be achieved. D. The grasshopper does not have a specialized circulatory system - instead, its circulatory system consists of the fluid in the body cavity which is circulated by means of the body movements of the animal. E. Both B and C are true of the circulatory system of the grasshopper.arrow_forward
