What is the purpose of the gills of a fish, and what is the function of the gills?

Of course, you can, but see the following report, I have proof

Fish have gills, and I have "human gills".

Recently, Israeli scientist Alan Bodner invented a revolutionary underwater breathing apparatus that allows people to dive to the bottom of the ocean for a long time without carrying an oxygen cylinder, just like a fish with gills. This "human gills" underwater breathing system can not only change the diving pattern in the future, but also change the design of the submarine.

The method of respiration in fish was the inspiration for Bodner's invention of the "human gills" underwater respiratory system**. Bodner pointed out that fish do not chemically separate oxygen from the water, but rather dissolve oxygen to sustain their lives, and he invented the "human gills" to provide divers with the oxygen they need to breathe: a centrifugal device installed inside the instrument that rapidly rotates the seawater to change the pressure of the seawater, thus pumping the oxygen needed in the water.

The underwater breathing apparatus is propelled by a rechargeable battery and is fairly lightweight. According to Bodner's calculations, 1 1-kilogram fully charged lithium battery is enough for a diver to dive for 1 hour.

Definitely not, are you too much of fantasy?

Nature is so hard to make it all the hard way around. It is too difficult to extract a large amount of oxygen in water, and the current technology cannot extract it efficiently, and the cost is not as good as bringing an oxygen cylinder directly.

The respiratory system of fish is gills. On both sides of the head, there are two large gill covers, and the cavities inside the gill covers are called gill cavities. Lifting the gill cover, you can see that there are four gills on each side of the throat, and each gill is divided into two rows of gill pieces, each row of gill pieces is composed of many gill filaments arranged in an arrangement, and many small gill filaments are born on both sides of each gill filament.

When the fish is in the water, each gill plate, gill filament, and gill segment are fully opened, so that the contact area between the gills and the water is expanded, increasing the chance of ingestion of dissolved oxygen in the water. There are microvessels in the gill patches, where the epidermis is very thin, and when the blood flows through it, the gas exchange is completed: the carbon dioxide brought by passes through the thin walls of the gill patches and is sent to the water; At the same time, it absorbs oxygen from the water, and the oxygen is transported to all parts of the body with the blood circulation.

Due to the alternating opening and closing of the mouth and gill cover, water can continuously enter the oral cavity from the mouth, reach the gill cavity through the pharynx, contact with the gill filament, and then discharge from the gill hole to the outside, and the respiration of the fish is completed in this process.

The question is, if there is such a thing, the blood has to flow, right? Would you like to?

The fish with exposed cheeks is clumsy, blunt, smiling, clumsy, apricot cheeks, peach cheeks, clumsy cheeks, scratching the cheeks, exposing the cheeks.

1. Respiration: This is the main function, the surface of the gill filaments is covered with micro-capillaries, and the dissolved oxygen in the water enters the blood through the blood vessels and plays a role in respiration.

2. Excretory organs: The gills of seawater bony fish contain chlorine-secreting cells, which can secrete chloride, so seawater fish can live in seawater with high salinity; And freshwater bony fish.

The gills can absorb chloride from freshwater and achieve a water-salt balance in the fish.

3. Filter feeding: especially plankton.

In prevorous fish, plankton in the water are filtered through gill filaments and enter the mouth for feeding. For example, silver carp.

Bighead carp feed entirely on their gills.

Gills: gills occur on both sides of the posterior end of the pharynx. The respiratory organs of most aquatic animals absorb oxygen dissolved in water.

The gills are mainly found on the sides of the head. The gills include three parts: gill raker, gill filament, and gill arch. The gill filaments are the main part of the gills, and the inside is densely covered with capillaries.

1. Respiration: This is the main function, the surface of the gill filaments is covered with capillaries, and the oxygen in the water enters the blood through the blood vessels for respiration.

2. Filter feeding: especially plankton-eating fish, plankton in the water enter the mouth for feeding through gill filaments. For example, silver carp and bighead carp rely entirely on their gills for feeding!

3. At the same time, it is also an important excretory organ, and the lesion of gill tissue will cause the excretion of ammonia nitrogen to be blocked, and the content of ammonia nitrogen in the blood will increase, which will affect the osmotic pressure regulation function in the fish.

The gills are the respiratory organs of most aquatic animals, and their position, morphology, and structure vary greatly. Depending on whether the gills are exposed or not, they can be divided into two categories: inner gills and outer gills. Most of the gills of fish are internal gills, referred to as gills, which are born on both sides of the head, protected by a gill cover, and communicate with the outside world with gill holes.

The gills are made up of gill segments arranged with comb-like gill filaments densely covered with capillaries, which are where the fish exchange gases. As water passes through the gill filaments, the capillaries take up the dissolved oxygen in the water and excrete carbon dioxide into the water.

In addition to being the respiratory organ of fish, the gills are also important excretory organs, and the lesions of the gill tissue will cause the excretion of ammonia nitrogen to be blocked, and the content of ammonia nitrogen in the blood will increase, which will affect the osmotic pressure regulation function in the fish.

Manta ray gills can be medicated.

In Asia, there is a folk custom of using it in medicine, believing that the gills of manta rays have the effects of clearing heat and detoxifying, penetrating acne rashes, and promoting lactation, but there is a lack of medical evidence to support it. However, its efficacy has not been recognized by the authority of traditional Chinese medicine.

Main information:

Manta rays, also known as manta rays, are named because their swimming posture is somewhat similar to bats flying at night, and is a collective name for several species of marine fish of the class Cartilaginous Fishes and Manta Rays. Manta rays have an irregular oval shape, with a body disc of about 50 100 cm, a maximum of more than 8 meters, and a weight of 3 tons.

Manta rays are mostly black or grayish-blue on the back, grayish and scattered with dark spots on the ventral surface, and the body shape is like a giant blanket, plus it has a round, thin tail at the back of its body, like a "sea kite". Manta rays have a migratory habit, so people don't see them in one place all year round.

Because its graceful and elegant swimming posture in the sea is similar to that of bats flying in the night sky, it is called "manta ray" in Chinese. Manta rays are so overwhelmed by their "alien" appearance that they can hardly associate with normal fish because they are so big that they can associate them with normal fish, but their ancestors swam in the ocean as early as the Jurassic period of the Mesozoic Era.
