Question

Каково значение дыхания в жизни животных?

Answer 1

Ответ:

Быстрый ответ

Дыхание – это процессы поглощения кислорода, использования его в организме в химических превращениях и вывода углекислого газа в окружающую среду.

Жабры – органы водного дыхания у ракообразных, рыб и личинок земноводных животных. Трахеи – сеть дыхательных трубочек ветвящихся внутри тела у насекомых, пауков и клещей.

Объяснение:

Дышат все живые организмы, так как для поддержания жизни необходимо постоянное поступление кислорода, а запасов его в организме нет. Кислород участвует в химических процессах расщепления сложных органических веществ, в результате которых выделяется энергия, необходимая для поддержания жизнедеятельности организма, его роста, движения, питания, размножения и многих других процессов.

The Importance of Breathing in the Life of Animals

Breathing is a vital process for animals as it plays a crucial role in supplying oxygen to their bodies and removing carbon dioxide, a waste product of cellular respiration. Oxygen is necessary for the production of energy through the process of aerobic respiration, which occurs in the mitochondria of cells. Without oxygen, animals would not be able to generate the energy required for their survival and various physiological functions.

Respiration in Animals: Animals have evolved different respiratory systems to facilitate the exchange of gases between their bodies and the environment. The respiratory system in animals can be categorized into two main types: external respiration and internal respiration.

External Respiration: External respiration refers to the exchange of gases between the animal's body and the external environment. This process typically involves the intake of oxygen-rich air or water and the release of carbon dioxide. The specific mechanisms of external respiration vary among different animal groups.

- In terrestrial animals such as mammals, birds, and reptiles, respiration occurs through lungs. These animals breathe in air through their nostrils or mouths, and the oxygen is absorbed into the bloodstream through the lungs. Carbon dioxide, a waste product, is then expelled from the body during exhalation. - Aquatic animals like fish, on the other hand, respire through gills. Gills are specialized organs that extract oxygen from water and release carbon dioxide. Fish extract oxygen from water by passing it over their gills, where oxygen diffuses into the bloodstream and carbon dioxide is released.

Internal Respiration: Internal respiration refers to the exchange of gases between the bloodstream and the body's cells. After oxygen is absorbed into the bloodstream during external respiration, it is transported to the body's tissues and organs. At the cellular level, oxygen is used in cellular respiration to produce energy, and carbon dioxide is produced as a waste product. Internal respiration allows for the exchange of oxygen and carbon dioxide between the cells and the bloodstream.

Conclusion: In conclusion, breathing and respiration are essential processes for animals as they enable the intake of oxygen and removal of carbon dioxide. These processes are vital for the production of energy and the proper functioning of an animal's body. Different animal groups have evolved various respiratory systems to suit their specific environments and lifestyles.
