Why do whales breath in their blowholes?

Answer 1

Whales use a blow-hole to take a breath when they come from under water because their mouth is not connected to their lungs like other mammals. They are not mouth breathers. They don't choke on food either.

Answer 2

Breathing through their blowholes allow more efficient gas exchange and convenient respiration. They can resupply gases while they were fractionally submerged or travelling at high speeds through the oceans. Whales can allocate for their breathing and eating mechanisms. Because there is a blowhole, whales do not have converged eating and breathing systems. Instead, the two systems diverge into the mouth and blowhole. Because whales breath with oxygen, they have to resurface to exhale and inhale or consequently, they will perish. The network of nasal passages underneath the hole would give rise to their unique method of communication by clicking and crying.

Answer 3

In Biology, a blowhole is the hole at the top of a Cetacean's head through which the animal breathes air. It is homologous with the nostril of other mammals. As whales reach the water surface to breathe, they will forcefully expel air through the blowhole. The exhale is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses. This spray, known as the blow, is often visible from far away as a white splash, which can also be partially caused by water resting on top of the blowhole.

Whales are mammals who breathe air into their lungs. Blowholes are a whale's nostrils and are located on the top or back of the whale's head. Blowholes are covered by muscular flaps that keep water from entering them when the whale is under water. In the relaxed state, the flap covers the blowhole. A blowhole leads to the whale's trachea and then to its lungs. Unlike us, whales cannot breathe through their mouth; they only breathe throught their blowholes.

At the surface of the water, whales open their blowhole(s) and exhale air explosively through their blowhole. This exhaled air from the blowhole is called the blow and usually forms a gusher or a bushy stream of misty air and vapor. This is immediately followed by inhalation of fresh air, and the blowhole(s) close again. (Blowholes are in a closed position when the whale relaxes.) This breathing pattern takes only a fraction of a second for small cetaceans (dolphins and porpoises), but it may take a few seconds for larger whales.

Just before a whale dives underwater, strong muscles surrounding the blowhole relax and the protective flap covers the blowhole.

Whales cannot breathe through through their mouths (like people can). Their trachea (the tube to the lungs) and esophagus (the tube to the stomach) are not connected.

Why do some whales have one blowhole and some have two?

Most mammals have two nostrils (blowhole equivalents). One of the nostrils (air-passages) of toothed whales evolved into their echolocation system (the sensing system in which they make and receive high-pitched sounds in order to orient themselves, catch prey, and communicate), leaving them with only one blowhole.

Answer 4

Blowholes are for breathing air, basically like nostrils. Whales are mammals and can't breathe under water. The blowhole is located on top of the head so that the whale only needs to expose a small part of its body above water when breathing.

Answer 5

A whale's blowhole functions like a nostril. It breaths and exhales from it as a part of its respiratory system. When you see a whale spew water from it, that's the whale exhaling!

Answer 6

Blue whales do have blow holes because some of them are mans so the mans whales have the blow holes in their body

Answer 7

Whales have blow holes so they can breath , just like on a human we have nostrils.

Answer 8

Whales breathe through their blow hole.
