Question

What is a limitation of the fish circulatory system?

a. Blood is pumped to the gills with too high a blood pressure and this sometimes reverses the counter-current flow of blood and water across the gills

b. Blood that reaches the heart is O2-poor, so keeping the heart muscle itself well oxygenated can be a limitation for strenuous swimming c. Blood is pumped to the tail muscles with too low a blood pressure for extended muscular effort

d. O2-poor blood is not pumped directly from the heart to the gills

Explanation / Answer

b. Blood that reaches the heart is O2-poor, so keeping the heart muscle itself well oxygenated can be a limitation for strenuous swimming. this is the limitation for the fish circulatory system
