What are some of the small creatures that can easily penetrate the human dermis?

Bullet ant, antidae, genus of chromogany, phylum arthropods, is mainly found in the rainforests of the Amazon region, and is similar in appearance and appearance to the ancestors of wasps, with little change for millions of years. Bullet ants, which have been rated as one of the "top ten most poisonous animals in the world", are an outlier of the ant family. From a distance, they look like bees, but they have strong and powerful upper wings and sharp and venomous tail spines; It looks like an ant up close, and likes to wave a pair of big tongs to show off its might.

With a body length of about 3 centimeters and about 5 times the size of the common ant, they are one of the largest ant species in the world. Its bite easily crosses your dermis and is not painful, but the problem is that it secretes a paralytic neurotoxin that affects voltage-dependent sodium channels and blocks synaptic transmission in the central nervous system. It will make you feel the same pain as being hit by a bullet.

Experiments are underway abroad on possible medical applications. Justin Schmidt describes it this way: "It's like having a rusty nail stuck in your heel and then walking barefoot on fiery charcoal."

Under normal circumstances, a bite from one or two bullet ants is not fatal, but the pain can spread quickly, sometimes even if your hand is bitten, your shoulder will hurt, and even your entire arm may not be able to move for a few hours. I don't know if the subject is talking about the wilderness in **。。。 Hopefully it won't be bitten by this little creature.

Hookworm - the larvae of hookworms, pass through ** and tissues, enter the circulatory system, then in the lungs, through the respiratory tract, enter the digestive tract, and then reach the parasitic site. There are two main types of hookworms that parasitize the human body, one is the duodenal hookworm nematode and the other is the American plate mouth nematode. <>

Dimethyl sulfoxide is abbreviated as DMSO, which is very penetrable**, and it is an extremely useful chemical solvent that can bring other substances dissolved in it into the body.

Correct the mistake on the first floor!! Water can't enter the human body through **, no matter how much water is applied, it can only be in the epidermis, and the dermis can organize any biological macromolecules to pass through, otherwise you won't bubble up after soaking in water for a few hours? Is it okay to take a bath when you are thirsty?

When the water enters the human body, it will not be thirsty?? The tightness of the membrane of the human dermis is not known to most people! As long as life exists, people are alive, and the vast majority of molecules will be prevented from entering.

Even the excretion of water in the human body (such as sweating) is excreted through glands such as sweat glands, rather than directly from the cortex.

If it is an ultra-fine and ultra-small molecule, it can be (note that water is not an ultra-fine molecule, it is still relatively large), and there are not many of these things, such as some micromolecular essential oils, some viruses, etc.

The simplest and most common is Shuibei.

It depends on what kind of substance you want.

There is a lot of substance. It depends on what type.

Sunlight contains ultraviolet rays.

As long as there is magnetism, there will be radiation, and the greater the radiation, the greater the harm to people!

The effect of amino acids on the skin: makes ** smoother and more elastic.

Amino acids are the smallest units that make up proteins and work directly to the dermal fibroblasts. It can completely penetrate epithelial cells, has biological activity, and has a significant improvement in appearance and skin texture after use, but does not affect the barrier function, and can chelate with divalent metal ions in the inner layer.

Prevent too many divalent metal ions from cross-linking with collagen in **, maintain enough collagen fibers and elastic fibers, and make **silky, delicate and elastic.

Amino acids are the building blocks of the body, they make up proteins, and of the 22 known amino acids, eight are called "basic" amino acids that cannot be produced enough in the body to maintain growth and health, because they are essential amino acids for maintaining good health.

Amino acids are the building blocks of proteins, which are the building blocks of muscles, glands, organs, tendons, enzymes, nails, and hair. This makes the status of amino acids crucial.

It mainly affects the eyes and induces cancer, causing acute keratitis and conjunctivitis, chronic cataract and other eye diseases. In addition, ultraviolet radiation can also promote the accelerated chemical decomposition and aging of various organic and inorganic materials. Accelerate the aging process of polymer polymers, promote the fading of pigments and dyes; Plankton in the ocean can also be affected by ultraviolet radiation, which can affect growth and even die; Ultraviolet radiation is also an important factor in the production of harmful photochemical smog. Ultraviolet radiation will bring serious harm and impact to the physiology, growth and development of various animals and plants, including humans.

This should be taken seriously. For this reason, scientists from all over the world have reminded people that they should pay close attention to the harm of ultraviolet radiation to the human body and take necessary precautions. Ultraviolet light contains three kinds of rays: UVA, UVB and UVC, and they have different effects on **.

The wavelength of UVA rays is 320 400 nanometers, also known as the tanning segment, and the transmission power can reach the dermis of the human body, which has the characteristics of strong penetration, slow and long-lasting action. Although UVA does not cause ** acute inflammation, it has a strong penetration of glass, clothing, water and the human epidermis, which can first penetrate the epidermis to reach the bottom layer of the skin and latent up, which will seriously disrupt the skin's immune system over time, resulting in an increase in oxidative free radicals in the body and damage to elastic tissues, resulting in premature aging of the skin, excessive keratin, rough epidermis, wrinkles and spots, muscle relaxation, sagging, and increasing UVB damage to the human body.

The wavelength of UVB rays is 280 320 nanometers, also known as the sunburn segment, the transmission force can reach the human epidermal layer, can cause erythema, is the main band of sunburn, light can cause redness, swelling, pain, severe blisters, peeling.

Excessive exposure to UVA and UVB rays may cause DNA mutations in cells, leading to cancer. The wavelength of UVC rays is 200 280 nanometers, also known as the sterilization section, the transmittance is only to the stratum corneum, and most of it is blocked by the atmosphere, although it will not cause too much harm to the human skin, but the sunshine time should not be too long, and attention should be paid to the protection of the eyes and eyes

Upstairs, you've done a great job.

Of course, you will get a tan in the heat, which will absorb the moisture on your face!

Black is a healthy beauty, and everyone's aesthetic is different, for example, foreigners like those with freckles.

The beauty of the soul is the true beauty
