Within an open circulatory system, such as that operating in insects, the body fluid, called hemolymph, bathes the organs directly as it is pumped between open spaces in the body. In which of the following animals are the blood and the interstitial fluid considered to be the same body fluid? In which of the following animals are the blood and the interstitial fluid considered to be the same body fluid? A grasshoppers B fishes C sparrows D dogs E jellyfish and cnidarians A Arteries carry blood _____. A away from capillaries B away from the heart and away from the lungs C to the heart and away from the lungs D to the heart only E away from the heart only E Blood returns to the heart via the _____. A aorta B pulmonary arteries C pulmonary veins D aorta and pulmonary arteries E aorta and pulmonary vein C Pulmonary veins carry oxygenated blood from the lungs to the left atrium. From the pulmonary veins, blood flows to the _____. A right atrium B left atrium C aorta D capillaries of the lungs E posterior vena cava B Blood enters the left atrium via the pulmonary veins From the anterior vena cava, blood flows to the _____. A right atrium B left atrium C aorta D capillaries of the lungs E posterior vena cava A Blood enters the right atrium from the anterior and posterior venae cavae. From the capillaries of the abdominal organs and hind limbs, blood flows to the _____. A right atrium B left atrium C aorta D capillaries of the lungs E posterior vena cava E Circulatory systems compensate for A the problem of communication systems involving only the nervous system. B temperature differences between the lungs and the active tissue. C the need to cushion animals from trauma. D the slow rate at which diffusion occurs over large distances. E the need fetal organisms have for maintaining an optimal body temperature. D Which of the following best describes an artery? A Arteries contain valves. B Arteries carry oxygenated blood. C Arteries carry blood away from capillaries. D Arteries carry blood away from the heart. E Arteries have thin walls compared with veins. D Both arteries and veins are defined by the direction relative to the heart in which blood is transported. Carbon dioxide enters the blood at the _____. A capillaries of the lungs B capillaries of the abdominal organs C capillaries of the hind limbs D capillaries of the head and forelimbs E capillaries of the head, forelimbs, abdominal organs, and hind limbs E oxygen content of the blood is the greatest at the aorta, left atrium, and pulmonary vein the two places that oxygen leaves the blood are capillaries of the head, forelimbs, abdominal organs, and hind limbs blood vessel walls are the thinnest at the capillaries blood pressure The hydrostatic force that blood exerts against the wall of a vessel. blood pressure is highest at the aorta carbon dioxide leaves the blood at the capillaries of the left and right lung where is the heart beat initiated? the right atrium where does blood move the fastest? blood moves the fasted at the aorta oxygen enters the blood at the capillaries of the left and right lung where does blood move the slowest? in the capillaries (slow) where is blood pressure the lowest? the anterior and posterior vena cava The _____ has(have) the thinnest walls. A aorta B capillaries C posterior vena cava D pulmonary artery E right ventricle B;The thin walls of the capillaries facilitate gas exchange Most gas exchange with blood vessels occurs across the walls of the alveoli double circulation A circulation scheme with separate pulmonary and systemic circuits, which ensures vigorous blood flow to all organs. pulmonary vein one of the two veins that returns oxygenated blood from the lungs to the left atrium aorta the large artery that carries oxygenated blood from the left ventricle to branch arteries for distribution throughout the body atrium (atria) a thin-walled chamber of the heart that receives blood from veins and pumps it to a neighboring chamber (the ventricle) the right atrium receives oxygen-depleted blood throug
