Jun 21, 2021 · Whereas humans breathe through their nose and mouth, whales have a blowhole on the top of their head—or two in the case of baleen whales. This is “like a nostril,” says Cunningham. While...
As whales reach the water surface to breathe, they forcefully expel air through the blowhole. The exhalation is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses.
Sep 5, 2020 · They take a massive breath and then hold it between 7-30 mins, or if you are a sperm whale you can hold your breath for up to 2 hours. After they hold their breath they let it out once they reach the surface letting out a huge burst of air.
This adaptation allows whales to breathe while swimming just below the surface. When a whale surfaces, it quickly opens the blowhole to inhale fresh air, which travels directly to their lungs via the trachea. The blowhole is lined with specialized muscles that close rapidly after each breath, ensuring that no water can enter.
Sep 22, 2020 · This is how water and pollutants can enter the animals’ respiratory tracts, scientists conclude. A humpback whale spouts water from its blowhole. New research shows the blowhole isn’t as protective as scientists had thought, and water and pollutants may be getting into whales’ lungs.
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
Whales cannot breathe through their mouth because, unlike terrestrial mammals, their digestive system and respiratory system are not connected. The blowhole leads to the nasopharynx, or nasal duct.
