Do insects have no lungs? Through what channels do you breathe?

Yes, insects don't have lungs.

Insects breathe or collect oxygen through a branchy network called the trachea. These tubes have ventilation holes located in the chest and abdomen. Oxygen enters the vents, flows down the tubes, and dissolves into the liquid located at the bottom of each tube.

This fluid then moves into other cells to provide oxygen to the insect's body tissues.

Insects can be seen under a microscope breathing air through their mouths, but rarely opening their mouths. This air obtained through the mouth does not provide the oxygen that the cells need because insects do not have lungs. They must rely on the air entering the vents and provide the cells with the oxygen they need through a network of dendritic networks.

Insects do not have lungs, they breathe with a valve tracheal system.

Most terrestrial insects breathe through the tracheal system. The abdomen of these insects is divided into many somites, and each segment is flanked by a pair of small holes called valves. The valves are connected to the tracheal system in the body and rely on the contraction and expansion of the abdomen to draw and expel air.

The ventilation and diffusion of the tracheal system allow the tissues in the body to directly absorb oxygen from the atmosphere and expel carbon dioxide.

The insect does not have a lung as an organ, it has a special respiratory system, which consists of a valve and a trachea, which are on both sides of the insect's abdomen, which correspond to the nostrils, and then breathe through the trachea.

Insects have relatively simple body organs, no lungs, and rely on valves to breathe. The valve then supplies oxygen to the cells through the air dissolved in the tube.

Breathing through the tracheal system: Most terrestrial insects breathe through the tracheal system, relying on the ventilation and diffusion of the tracheal system to directly absorb oxygen from the atmosphere and excrete carbon dioxide from various tissues in the body. Breathe with the body wall:

Some insects have no or only an incomplete tracheal system, and gas exchange occurs directly through the body wall, such as springtails. Breathing with tracheal gills: The juvenile stage of insects such as mayflies, cocooptera, and hairyoptera live in water, and part of their body wall protrudes into a thin or filamentous structure called tracheal gills, which uses the partial pressure difference between tracheal gills and oxygen to take in oxygen.

1. Breathing with the tracheal system: Most terrestrial insects breathe through the tracheal system, relying on the ventilation and diffusion of the tracheal system to directly absorb oxygen from the atmosphere and discharge carbon dioxide from various tissues in the body.

2. Respiration through the body wall: Some insects do not have or only have an incomplete tracheal system, and gas exchange is carried out directly through the body wall, such as springtail insects.

3. Breathing with tracheal gills: the juvenile life of insects such as mayflies, poptera, and hairyoptera lives in water, and part of their body wall protrudes into a thin sheet or filamentous structure called tracheal gills, and uses the partial pressure difference between tracheal gills and oxygen to absorb oxygen.

4. Respiration with snorkels, air films, and bubbles: the valves of some aquatic insects in the juvenile or adult stages are reduced, and a long snorkel is often formed at the end of the abdomen, with a valve opening on it, and oil is secreted around the valve or there are water-repellent hairs to break the surface tension of the water and absorb the air on the water surface. Such as rat maggots, water fly larvae, mosquito larvae, scorpion bugs and opossum bugs.

5. Breathing mode of parasitic insects: similar to the breathing mode of aquatic insects, parasitic insects rely on the osmosis of the body wall to absorb oxygen from the host fluid or tissue, or penetrate the host wall with the valve to obtain oxygen from the atmosphere.

Insects need to breathe and oxygen. However, insects do not breathe through their mouths or noses, but through small holes on both sides of their abdomen, also known as stomata. Because it is on both sides of the abdomen, in the case of cockroaches, although when the cockroach falls into the water, it is floating on the water, but the cockroach's stomata are under the water surface, so they will still drown, and you can also observe the larvae of butterflies and moths that scare caterpillars, and where the body is close to pseudopods (caterpillars are also 6 legs), there will be black little by little, and the skin is a stomat, and gas exchange is done directly.

Insects need oxygen to breathe However, insects do not breathe with lungs, but breathe through small holes on both sides of the abdomen, also known as stomata The mystery of the insect world is surprising everywhere - the species and number of insects are not only numerous and complex, but also the appearance and habits are varied, which is breathtaking. Because insects have the characteristics of small size, rapid growth and strong fecundity, they are indispensable members of the earth's ecosystem, which can help many plants to pollinate, and even develop a subtle radical co-evolutionary relationship with plants. Insects are an important food for all kinds of birds, amphibians and reptiles**. Nearly a million species of insects have been named, accounting for more than three-quarters of the largest known animal species on Earth, and it is estimated that between three and five million more species may remain undiscovered.

Such a large and abundant insect resource has not attracted everyone's relative attention to insects, mainly because only a few of the many insects have a direct interest in humans. As a result, the indiscriminate use of pesticides and pesticides, as well as the deforestation of forests, which are the main habitats for insects, have disappeared as a result. In 1989, COAG included a variety of insects in the list of endangered and rare protected wild animals, such as:

Stag beetle, walking bug, gidding, etc. Fortunately, in recent years, people have noticed the importance of saving the earth's environment and protecting biodiversity, and have also learned that all life on earth has the right and value to live. Now let's start learning and getting to know more insects!
