Question
a. Sauropod dinosaurs had access to less oxygen that large mammals of today. Thus, the dinosaurs might have had, smaller blood volumes, higher amounts of respiratory pigments in blood, fewer red blood cells, less myoglobin in tissues, hemoglobin that had a lower P50, and potentially higher blood [H+] or PCO2
b. Sauropod dinosaurs had access to less oxygen that large mammals of today. Thus, the dinosaurs might have had, larger blood volumes, higher amounts of respiratory pigments in blood, higher number of red blood cells, more myoglobin in tissues, hemoglobin that had a lower P50, and potentially higher blood [H+] or PCO2
c. Sauropod dinosaurs had access to more oxygen that large mammals of today. Thus, the dinosaurs might have had, larger blood volumes, higher amounts of respiratory pigments in blood, higher number of red blood cells, more myoglobin in tissues, hemoglobin that had a lower P50, and potentially higher blood [H+] or PCO2
d. Sauropod dinosaurs had access to less oxygen that large mammals of today. Thus, the dinosaurs might have had, larger blood volumes, lower amounts of respiratory pigments in blood, higher number of red blood cells, less myoglobin in tissues, hemoglobin that had a higher P50, and potentially lower blood [H+] or PCO2
Given what we know about animal responses to environmental hypoxia, what differences in the respiratory physiology of the Sauropod dinosaurs (the really big ones) would you expect to see as compared to the largest land mammals of today?
Explanation / Answer
b. Sauropod dinosaurs had access to less oxygen that large mammals of today. Thus, the dinosaurs might have had, larger blood volumes, higher amounts of respiratory pigments in blood, a higher number of red blood cells, more myoglobin in tissues, hemoglobin that had a lower P50, and potentially higher blood [H+] or PCO2 is the correct option.
