Which outcome occurs when a marine mammal rapidly ascends from deep dives to sea level?

💡 Explanation

When a marine mammal rapidly ascends, decompression occurs because reduced pressure causes dissolved nitrogen to come out of solution, triggering vasodilation to accelerate nitrogen excretion which may then leads to the formation of nitrogen bubbles in tissues, causing decompression sickness. Therefore gas bubble formations result, rather than buoyancy loss, hypothermia, or oxygen poisoning, each from distinct mechanisms.

• Which outcome occurs when a mammal uses vasodilation at high altitude?
• Which outcome occurs when a hibernating mammal experiences a transient temperature rise?
• Which physiological outcome directly compensates for reduced ATP production during mammalian hibernation?
• Which physiological challenge increases for freshwater fish adapted to rapid salinity increases?
• Which lift generation failure occurs when a swift's high-speed, low-altitude flight encounters significant thermal updraft shear?
• Which outcome predictably occurs when marine mammal core temperatures drop rapidly?
