Which of the following are the only vertebrates in which blood flows directly from respiratory organs to body tissues without first returning to the heart? A. Amphibians B. Reptiles C. Fishes D. Mammals 23. Why is the velocity of blood flow the lowest in the capillaries? Capillaries are far from the heart and the blood flow slows as the distance increases. A. B. The total cross-sectional area of the capillaries is larger than the total cross-sectional area of the arterioles. The diastolic blood pressure is too low to deliver blood to the capillaries at a high flow rate. C. D. All of the above 24. Where are semilunar valves found in the mammalian heart? A. B. C. D. Between the ventricles and the aorta or pulmonary trunk. Between the atria and the vena cavaes. Between the atria and ventricles. On the right side of the heart only. 25. Slugs are known to have one atrium and one ventricle with vessels emptying into the body cavity Which of the following is TRUE regarding the slug's circulatory system? A. It is considered a closed system because it only has one heart. B. It is considered an open system because it relies on body movements to circulate the hemolymph. C. It is likely that slugs have a similar circulatory system to earthworms based on their phylum classification D. As an endotherm, it is likely that slugs have a double circulation.Explanation / Answer
22. The only vertebrates in which blood flows directly from respiratory organs to body tissues without first returning to the heart are the Fishes
23. Because capillary beds have a total cross-sectional area much greater than the total cross-sectional area of the arterioles.
24.pulmonary and aortic valves located between the right ventricle and the pulmonary artery and between the left ventricle and the aorta
25. B
A Snail has an open circulatory system which means that blood is not restricted from travelling within the blood vessels. ... The fluid that is transported through the circulatory system of a Slug is called hemolymph.
