Blowhole (anatomy) - Wikipedia
In cetology, the study of whales and other cetaceans, a blowhole is the hole (or spiracle) at the top of the head through which the animal breathes air. In baleen whales, these are in pairs. It is homologous with the nostril of other mammals, and evolved via gradual movement of the nostrils to the top of the head. [1] .

Whales | Smithsonian Ocean
Both baleen and toothed whales breathe through blowholes (the whale’s version of nostrils). These are found on the top of their head and connect to their lungs. Because cetaceans only eat through their mouths, which is not connected to their lungs, they are able to reduce the possibility of drowning from water moving into their lungs while ...
Respiratory physiology in the dolphin and other whales

How Can Whales & Dolphins Hold Breath For So Long …
2023年10月19日 · Whales and dolphins can hold their breath for so long underwater because they have efficient respiratory systems, they can conserve energy underwater by purposely slowing their heart rate, constructing select arteries and limiting blood supply to only a few organs, and they have a protein in their muscles called myoglobin that stores oxygen.
Respiratory System - Baleines en direct
Since whales are mammals, they must breathe out of the water, like humans. Their respiratory system therefore functions similarly to that of land mammals, but has adaptations specific to their underwater environment. When the animal inhales, air passes through the blowhole, nasal duct, larynx, trachea, and lastly the lungs.
