Animal respiration is urgently needed, what are the ways animals breathe

Mammal. body surface coat, viviparous, lactating; Rely on the movement of the limbs, unable to fly; breathe with your lungs; homeothermic animals; It is found both on land and in the ocean, mainly on land.

Arthropod. Body surface segmented, exoskeleton, oviparous; Movement on the feet, some can fly (some insects); Hydroacoustic types breathe with gills or book gills, and terrestrial types breathe with trachea; ectotherms; It is distributed both on land and in the sea, and is extremely widely distributed.

Birds. body surface is feathered, oviparous; Relying on foot and wing movement, most can fly; double breathing with the lungs and trachea; homeothermic animals; It lives mainly on land or in offshore areas.

Fish. Body surface with scales, oviparous; fin paddling; breathe with gills; ectotherms; They only live in water and can be divided into freshwater fish and saltwater fish.

Birds are animals that breathe with air sacs.

The respiratory system of birds is very specialized, which is manifested in the fact that there is a well-developed air sac system that communicates with the lungs and trachea. The balloon is widely distributed in the internal organs, bone cavities, and between certain motor muscles.

When the bird is resting, it mainly relies on the movement of the intercostal muscles and abdominal muscles to breathe in the lungs. When flying, it mainly relies on the movement of the pectoral muscles to breathe. In addition to the lungs, the bird's respiratory organs also have air sacs formed by protruding lung walls to help the lungs breathe twice.

role

The airbag is the second secret that birds use to fly high**: it's not just because the airbag helps with breathing.

Airbags also play an important role for flying birds: they increase buoyancy. In an airtight environment where the air is thin and the lift provided by the bird's wings is reduced, the inflatable airbag reduces the overall density of the bird itself, so that they do not fall due to lack of buoyancy.

The key message is that double breathing allows the bird to maximize the oxygen consumption in the air, and the presence of air sacs allows the bird to have enough buoyancy in the thin air.

But the bird's bones are fragile. Bird bones are hollow, have no marrow, and are thin and long, which makes them very susceptible to injury. Their bones are very resistant to impacts, and falls, impacts, fights, and even strong winds can easily cause bird fractures.

The internal organs of birds are also very fragile. Not to mention the rest, their airbags are really just a membrane, which can be described without exaggeration as "blown-to-break".

What organs are driven by fish respiration.

The breathing modes of animals are epidermal respiration, tracheal respiration, gill respiration, and lung respiration.

1. Epithelial respiration.

Cell membranes are permeable to both O2 and CO2, and some animal membranes can act as gas exchangers. Leeches, earthworms and other annelids have no specialized respiratory organs, and their ** is full of blood vessels and has a gas exchange effect. Frogs have lungs, but they still play an important role in breathing, and frogs during hibernation rely almost entirely on them for breathing.

2. Tracheal breathing.

Tracheal respiratory insects are covered with cuticles, which are not easily permeable to water and air, which prevents water loss. The trachea is the respiratory organ of insects. The microtrachea extends directly into the cell, enabling gas exchange between the cell and the trachea.

Because the tracheal system directly transports O2 to the cells, and the CO2 in the cells is also directly eliminated through the tracheal system, the diffusion rate of O2 and CO2 in the tracheal system is very fast, about 10,000 times faster than in blood or water.

3. Gill respiration.

Gill respirationIn addition to ichthyidae, molluscs such as octopuses and squid, and crustaceans such as shrimp and crabs also use gills to breathe. The mechanism by which the water flows through the gill filaments is different for each type of animal, and the fish rely on the lifting of the bottom of the mouth and the co-ordinator of the gill cover to act in the same way; Shrimp rely on the movement of abdominal appendages; The squid rests on the opening and closing of the mantle. Semi-parasitic lampreys suck on other fish by mouth, and breathe through the contraction of the muscles on the gill sac wall.

4. Rent back the lungs to breathe.

Pulmonary respiration, or pulmonary ventilation, is achieved through breathing exercises. The lungs are divided and contain smooth muscle fibers, and the thin-walled surface is covered with capillaries. During lung ventilation, the glottis closes, the nostrils open, the floor of the mouth descends, the air enters the pharynx and closes the nostrils, and the floor of the mouth is pressed upwards to press fresh air stored in the pharynx into the lungs; The glottis closes, the nostrils open, and the floor of the mouth moves several times, allowing the pharyngeal gas to renew.

The respiration mode of organisms is adapted to the living environment and their own structural characteristics Different organisms, living in different environments, and different respiration modes For example, insects belong to arthropods, live in a relatively arid environment, and use the trachea to breathe; Amphibians, which can live both in water and crawl on land, breathe with their lungs, ** assisted breathing; The breathing mode of birds is double breathing, when inhaling, part of the gas enters the lungs, and a part of the gas exchange takes place in the lungs, and a part enters the air sac, which is stored in the air bag When exhaling, the gas in the air bag enters the lungs, and gas exchange takes place in the lungs Therefore, for each breath, the gas passes through the lungs twice, and the gas exchange is carried out in the lungs twice This greatly improves the efficiency of gas exchange, which is suitable for the flight of birds; Whales belong to the family of mammals and live in the water and breathe with their lungs; Shrimps and others belong to arthropods that live in water and breathe with gills; Paramecium is a single-celled animal that relies on the surface of the body for respiration

So the answer is:

Mammals breathe with their lungs. Unlike fish, which respire with gills, all mammals, whether they live in water, such as whales, dolphins, or humans on land, have in common that they breathe with their lungs, and mammals have a well-developed respiratory system, especially in terms of respiratory efficiency. Air enters the lungs through the external nostrils, nasal cavity, larynx, and trachea, where gas exchange is completed.

Quick facts about mammals.

The original mammals are more than 220,000 years old, and there are more than 4,000 species in existence.

Mammals have the most complex lung structure. It is made up of a "bronchial tree", and the blind end of the bronchial branch is the alveoli. The large number of alveoli greatly increases the respiratory surface area and significantly improves the efficiency of gas exchange.

Mammals are homeothermic animals, almost all mammals have bones and fur, and the fur on the body surface can help maintain body temperature and adapt to various complex living environments.

Summary. Hello, glad to answer for you. The way threads breathe is:

The body structure of linear animals is simple, there is no special respiratory structure differentiation, and the cells on the body surface can be directly used to exchange gas with the external environment, and the breathing mode of the simple ** respiratory annelids is: annelids rely on the moist body surface to exchange gas with the outside world to breathe, annelids do not have special respiratory organs, ** there are abundant capillaries distributed inside, and there is a corneal membrane secreted by epidermal cells outside the body, ** can secrete mucus.

The current way of respiration of animals and annelids 1581585 that of nematozoa and annelids.

Hello, glad to answer for you. The exhalation and inhalation mode of nematozoites is: the body structure of linear animals is simple, there is no special respiratory structure to differentiate, and the cells on the body surface can be directly used to exchange gases with the external environment

Annelids rely on the moist body surface to exchange gases with the outside world to breathe, annelids do not have special respiratory organs, ** are distributed in the capillaries, there are cornea membranes secreted by epidermal cells outside the body, ** can secrete mucus.

The characteristics of annelids are that the body is composed of many annular body segments similar to each other, earthworms make their bodies move through the cooperation of muscles and bristles, and the body segments can enhance the flexibility of movement, relying on the moist body wall for breathing, annelids belong to ectothermic animals The living environment and life history of linear animals are complex and diverse. Camp free life, aquatic species are generally benthic life, seafood zui many, from the beach to the very deep seabed, sometimes a large number, become a large number of seabed multicellular animals, freshwater life species exist in a variety of freshwater environments, even in the rapids can also be seen, often its tail gland secretion of mucus fixed on water objects; Some types of hot springs can sometimes be found in environments where the water temperature is as high as 37.

Breathing creatures are frogs, snails, mice, lions, etc.

The way creatures breathe:

1. Gill respiration.

The main way fish breathe. Respiration is mainly carried out on gill patches (gill filaments in bony fish), which are composed of a single layer of epithelial cells, Sertoli cells, and capillaries. When water flows through the gill patches, the CO2 carried by the red blood cells in the capillaries can be fully exchanged with the O2 in the water.

2. Lung respiration.

Like us humans, lung-breathing animals are adapted to live on land and drown if they stay underwater for a long time without breathing.

3. Plant respiration.

First of all, the respiration of plants is the process necessary for plants to obtain life, this process is divided into aerobic respiration, anaerobic respiration, under aerobic conditions, the glucose in the plant body decomposes glucose through reaction with oxygen, and releases a large amount of energy.

To provide plants for life, when there is a lack of oxygen, plants decompose glucose into lactic acid or alcohol, but release a small amount of energy, which is a last resort for plants, barely maintaining life, and releasing more or less energy.
