What do white blood cells do?

As you know, blood, so necessary for life, is not such a simple thing. Many different substances do their jobs and are important in their own way. Although the red cells in the blood are much more numerous and give the blood its color, white blood cells also play a critical role. White blood cells are called leukocytes.

Most normal white blood cells are granular cells. These cells travel through the bloodstream to areas where there is an accumulation of microbes or damaged tissues. Some of these cells, called neutrophilic leukocytes, coat bacteria and destroy them. They also secrete substances that break down and soften dead tissue and form pus.

Another kind of white blood cells is called lymphocytes. The number of lymphocytes often increases in those parts of the body where the infection continues for a relatively long time. This is part of the body's effort to fight infection, so you can be sure they're doing a very important job.

There is another type of white blood cells called monocytes. Together with other cells in tissues, these cells have the ability to collect dead matter particles as well as coat dirt particles and prevent them from coming into contact with healthy tissue cells. By the way, although white blood cells are necessary for the body, when there are too many of them, this is also not very good.

When too many white cells are produced and they don't become the healthy, active cells that are needed, the condition is called leukemia, or blood cancer. Therefore, the composition of the blood, as a chemical formula, must have the right amount of all components - red cells, white cells, proteins, salts, carbohydrates, fats, and so on.

Random interesting fact from the Great Encyclopedia:

What do wasps build their nests out of?

One of the species of the wasp family is called hornets. They have a thick body, usually black or dark brown, with bright white or yellow markings. Therefore, they are also called "yellow jackets". Hornets are social insects. They live in groups and build nests. If their nests are attacked, they become very angry and sting the attacker painfully. Therefore, there is such an expression: "Angry as a wasp."

Hornets build large nests, sometimes up to a foot long, with a hole at the base. These nests are attached to the branches of a tree or bush, and sometimes under the overhanging roofs of buildings. What do hornets build their houses from? From paper! It must be said that the hornets are the first paper producers on Earth. They make paper from wood pulp.

Hornets collect wood from planks and trees that have been stripped of their bark. When harvesting wood, the wasps move backwards, scraping the wood with their jaws and wetting it as they come in. This forms round balls of paper pulp. When building a nest, the balls are pulled into plates.

Most people do not like hornets because they are afraid of their bites. They also harm fruits. But in reality, wasps are human friends, they help to destroy flies and other harmful insects.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Chocolate is not just a delicacy, but the mood and health of women 10.02.2024

Chocolate is not only a delicious treat, but also a powerful stimulator of endorphins and serotonin, which have a beneficial effect on mood and help reduce stress levels. This explains why one in four women consider chocolate the most enjoyable source of pleasure. The data comes from a survey conducted by the Italian Society of Gynecology and Obstetrics (Sigo).

For many women, chocolate is one of the strongest passions after intimacy. In addition, this product helps reduce pain. During premenstrual syndrome, about 68% of women use it, and during menstruation - up to 83%.

The study results indicate that chocolate improves mood in 97% of women surveyed and promotes feelings of arousal in 50% of them. They note that this delicacy relieves menstrual pain, eliminates headaches, relieves bloating and helps with insomnia.

The study confirmed that chocolate is an excellent aphrodisiac. Doctors note that women who regularly consume chocolate tend to be more sexually active and enjoy their sex life more.

It is important to note that the positive effects are associated specifically with dark chocolate, which contains more cocoa and less sugar compared to milk. Moderate consumption is limited to a few pieces per day, which helps avoid excess calories and sugar intake. People with high blood sugar levels should control their chocolate intake.

Chocolate, especially dark chocolate, is not only a tasty treat, but also a healthy product that can influence the mood and general condition of women. By supporting the production of endorphins and serotonin, it can be an integral part of your health and well-being. It is important to remember in moderation and choose a quality product for maximum benefit.
