What does blood do in the body?

Blood is necessary for life in all parts of the body. To understand this, you must first realize that the blood contains a lot of different substances and cells. There is a fluid here, a part of the blood called plasma. It contains many substances in dissolved form.

Let's take a look at some of them and find out what they do. Carbohydrates, such as sugar, are found in the blood to provide energy to the body. Fats are contained here for combustion or accumulation. Various salts can also be found in the blood, which serve the needs of the body. Blood plasma carries nutrients from the stomach and intestines to cells that would otherwise be hungry. In addition, plasma carries waste away from cells to the kidneys and intestines.

The blood also contains the secretions of many glands, which are also carried to various parts of the body. Red blood cells (erythrocytes), which give blood its color, contain a substance called hemoglobin. The body needs hemoglobin because it easily combines with gases such as oxygen and carbon dioxide. Red blood cells carry oxygen through the arteries and capillaries to all cells in the body. White blood cells (leukocytes) are also very important for the body. They destroy bacteria.

Other white cells (lymphocytes) are part of the body's process of fighting bacteria. Another variety of white cells (monocytes) is associated with dead tissue and dirt that can enter the body. There is another type of blood cells - platelets. They contribute to blood clotting so that wounds and cuts do not lose a lot of blood.

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 ... >>

titanium paper 07.04.2002

Titanium dioxide, in addition to its whiteness, which makes it possible to make excellent white on its basis, has another important property: when irradiated with daylight, it reacts with air moisture, forming free radicals. These active compounds, strong oxidizing agents, are able to destroy microorganisms and decompose harmful substances.

In Japan, the production of paper has begun, in which titanium dioxide has been introduced. For example, wallpaper, paper screens and wall calendars are made from it. From an unventilated room with such wallpaper, formalin vapors completely disappeared in three days, which were launched into the air every day for the experiment. In a room without wallpaper, the concentration of formalin increased. Titanium wallpaper decomposes formalin to CO2 and water. On the surface of titanium paper, E. coli dies within a day.

The possibility of issuing titanium paper in Germany is now being considered.
