When we receive a complete blood count, we cannot figure it out without the help of a doctor. Meanwhile, some indicators need to be known in order to at least a little navigate the situation. A separate column in the analysis form is the number of monocytes, which monitors the patient's recovery. For example, if after suffering a sore throat, an increased number of monocytes persists for a long time, then the doctor may suggest the development of incipient rheumatoid inflammation

Anatomically, our body is divided into topographic regions with various organs, neurovascular bundles and other components located within them. In this article, we will consider the planes and axes of the human body
The autonomic nervous system is divided into sympathetic and parasympathetic. Each of the departments performs functions that have a supporting and stimulating effect on the internal environment of the body
In 1910, the American physicist P. Bridgman and the German researcher G. Tamman discovered that ice can form several polymorphic crystalline modifications. Now 9 modifications of ice are known, they have different crystal lattices, different densities and melting points. The ice we all know well is called "ice I", other modifications of ice exist at pressures exceeding 2000 atm
Lanthanides and actinides are two families that contain 14 chemical elements each, as well as the metals themselves - lanthanum and actinium. Their properties - both physical and chemical - will be considered by us in this paper
Dicarboxylic acids are substances containing two functional monovalent carboxyl groups - COOH, which determine their acidic properties. However, this definition is short. In fact, much more can be said about these compounds, so now it is worth paying attention to the most interesting, useful and important facts regarding their chemical and physical properties, the production process and the areas in which they have found their application

Everyone feels the passage of time. Stars and planets are moving in the universe, the hands of the clock are monotonously beating their rhythm, each of us is slowly moving forward along the corridor of time. Realizing their dependence on it, people have come up with many ways and number systems that help to streamline and calculate it. Various sciences, such as mathematics, physics, chemistry and history, could hardly do without such an exact science as chronology
An X-ray laser is a device that uses stimulated emission to generate or amplify electromagnetic radiation in the near X-ray or extreme ultraviolet region of the spectrum, i.e. typically on the order of several tens of nanometers (nm) wavelength
Increasingly, we hear the expression "Boolean algebra". Perhaps it's time to understand the role of man in creating robots and the ability of machines to solve not only mathematical, but also logical problems
The ability of cells to respond to stimuli from the outside world is the main criterion of a living organism. The structural elements of the nervous tissue - the neurons of mammals and humans, are able to transform stimuli (light, smell, sound waves) into the process of excitation. Its end result is an adequate reaction of the body in response to various environmental influences. In this article, we will study what function the neurons of the brain and peripheral parts of the nervous system perform, and also consider
Iron is an element that is familiar to every person on our planet. And there is nothing surprising in this. Indeed, in terms of its content in the earth's crust (up to 5%), this component is the most common. However, only a fortieth of these reserves can be found in deposits suitable for development. The main ore minerals of iron are siderite, brown iron ore, hematite and magnetite

Disputes between idealists and materialists touch on many topics. But one of them literally pits both sides, causing a huge amount of raging emotions. This is the problem of progress. A very abstract noun causes almost holy wars. Is progress what it seems, or is it not? The very formulation of such a question is very, very difficult to understand. Let's dot all the vowels i that do not exist in Russian
What is the connection between music and exact sciences, like mathematics? People have been asking this question since ancient times. Modern scientists have proven that the mental processes that occur when solving mathematical problems are similar to those that occur during the performance of musical works and the study of subjects of the musical-theoretical cycle
People have always been interested in space. The moon, being closest to our planet, has become the only celestial body that has been visited by man. How did the research of our satellite begin, and who won the palm in landing on the moon?
A gravitational anomaly occurs both on the surface of the Earth and in its bowels. An important external factor in this case is the relief. As for the underground causes, they include the movements of the layers vertically and horizontally, as well as changes in the density composition of these layers. Such a phenomenon as a gravitational anomaly is of great importance in geology
More than other space objects since ancient times, the Moon has attracted man. Its reverse side, hidden from the earthly observer, gave rise to many fantasies and legends and was associated with everything mysterious and incomprehensible
The article describes the main parameters of the Earth's satellite: the size of the Moon, its volume and mass. As well as surface features, comparison with other objects of the solar system
Why the fox was called a fox. Why chanterelles are not wormy and are poisonous mushrooms wormy. Where and when is the best time to collect chanterelles. Signs of mushroom places. The healing properties of chanterelles and how they are related to why chanterelles are never wormy. What do the "twins" of the common chanterelle look like and can they be eaten
Nature always solves problems in the simplest and most elegant way you can think of. The golden ratio, or, in other words, the Fibonacci spiral, is a clear reflection of the genius of these decisions. Traces of this proportion are found in ancient buildings and great paintings, the human body and celestial objects
Volume is a characteristic of any figure that has non-zero dimensions in all three dimensions of space. In this article, from the point of view of stereometry (the geometry of spatial figures), we will consider the figure of a prism and show how to find the volumes of prisms of various types
The world of fish is very diverse, as is their habitat. They live in oceans, seas, rivers and lakes; they can exist both in warm tropical regions and in the cold waters of the Arctic Ocean. How are they different from other animals? What species and families of fish are there?

In the human body, more than 200 types of cells have been isolated, each of which has the same hereditary code. All of them developed first from a unicellular and then a multicellular embryo, which a little later divided into three germ layers. From each of its parts, body tissues have developed, where approximately the same type of cells are located. At the same time, almost all of them developed from the same group of predecessors. This process is called cell differentiation
In nature, there are many very interesting devices that help creatures live. They are found in both animals and plants, fungi, bacteria and others. It's amazing how inventive and unique the natural environment is! One has only to recall the diversity of species of various living beings, as this uniqueness becomes apparent
No one will deny that the reality around us is harmonious and perfect. It doesn’t matter what or who a person believes in, but around him he sees not only beauty and diversity, but also a harmonious order in which there is no place for chaos. Especially clearly clear expediency is manifested in the world of living beings. Everything weak, ugly, incapable of reproducing he althy offspring is swept away by the action of evolutionary factors, primarily natural selection
