    Can a man test positive for pregnancy? Oh sure, he can. Only it would not mean that he is pregnant, but that he is very seriously ill. All common pregnancy tests measure the presence of human chorionic gonadotropin hormone (hCG) in the body. It begins to be produced one day after the fertilized egg has attached itself to the uterine wall. Actually, two stripes on the test mean that the hormone is present in the body, which means that the embryo has already started its development.

    Clinical urinalysis Color. The normal color is straw-yellow. Brown, hazel color hints at liver disease and excess of bile pigments (bilirubin) in the urine, brown - at inflammation of the bladder (cystitis), especially if there is pain when urinating, and there is little urine in the analysis. Red indicates blood in the urine. From what? There are several reasons, from a pebble in the pelvis, which damaged the mucosa, to the decay of a tumor.

    Tooth development during embryogenesis Yeah, the embryo has them, too! Yet, of course, characterized by a reciprocal interaction between the oral epithelium and the mesenchyme beneath it. The image shows the gem of a mouse embryonic tooth.

    In order to get energy, we need to expend it. Of all the energy expenditures of our body, 10% go to the process of daily digestion☝🏻

    Meiosis resembles mitosis, but not quite We made this association since we have already touched upon this process more than once. Mitosis is cell division with the formation of two absolutely identical cells. This mechanism is characteristic of all cells in the body except for germ cells. They divide according to the rules of meiosis👇🏻 Four daughter cells are formed, but with not an identical set of chromosomes - each one is left with 13 pairs instead of 46. And also in meiosis two divisions (first into two cells and then they divide into two more). Reducing the number of chromosomes during meiosis is very important, because otherwise the number of chromosomes would increase from generation to generation🧬

    Well, how many calories are in 1 kg of our fat? After such a question you immediately like to go to the gym😁 Well, it is important to say that the normal level of fat is considered to be the range from 21 to 31% for women and from 14 to 25% for men. So, one gram of pure fat contains 9 kilocalories, but one gram of "our" fat contains about 7.7 kilocalories. Where does this difference spring from? The thing is that "our" fat contains a small amount of water, connective tissue and other ballast compounds. So, if we take the average percentage of fat in our body (22%) and the average weight (take the figure of 74 kg), then we get an average result - 16 kg. Bottom line: there are 123,000😁 kilocalories stored in human fat. Remark. 👉🏻 We do not pretend to the accuracy of calculations, just make our own interesting conclusions.

    Retinopathy An optic pathology in which the retina, the inner membrane of the eyeball containing the photoreceptors, is affected. The most common cause of retinopathy is vascular disorders, leading to bleeding👆🏻 As a result, a person has a narrowed field of vision, blurred vision, and photopsia (the appearance of bright "dots" in the eyes). The commonest cause of retinopathy is diabetes, as it affects blood vessels. Their walls lose their elasticity and vessels become brittle, so they are easily injured.

    How do veins and arteries differ in their structure? The answer to this question is most directly dictated by the function of these vessels. Arteries need to resist the high pressure inside the vessel - the heart tries to "push out" the blood with the greatest force. Therefore, arteries have an elastic sheath, which keeps them in shape. Besides, this type of vessels has to change their lumen in order to vary the level of blood flow. Therefore, they have a well-developed layer of muscle tissue. As a result, arteries are much thicker. But the veins themselves are pliable and inelastic, as they do not have such properties☝🏻 Although some of them (veins of the lower extremities) have another unique property - they have valves that prevent the backflow of blood.

    The walls of our stomach are completely renewed every three to four days Is that well-known fact real? Yeah, but not to the fullest extent. If you literally pour hydrochloric acid on the muscular lining of the stomach, the cells would die fairly quickly. But fortunately for us, our body has developed several defense mechanisms. And mucus, which creates a buffer between aggressive gastric juice and the wall. And also the high regenerative activity of the mucosa. Yet THE WHOLE gastric wall is not renewed in 3-4 days - it shouldn't be ALL damaged at all. Only the mucosa is in contact with the stomach's contents, and it is renewed in about this time frame.

    Circulatory system of the brain On the background of the smaller vessels, you can see quite large formations. For example, like going from the forehead to the back of the head. These formations are called venous sinuses or sinuses of the dura mater. They can be called vascular "manifolds." These pools (and so it is appropriate to call them from the anatomical point of view) collect blood from the internal and external veins of the brain. After that, the blood leaves the brain. By the way, the sinus "from the forehead to the back of the head" that we gave as an example at the beginning of the post is called the sagittal sinus.

    The little "stomach" inside the cell Lysosomes are organelles whose function is to digest various molecules and particles. Own or foreign, it does not matter. If necessary, the lysosome can even start self-digestion of the cell♻️ This "gastric" function of this organelle is due to the acidic environment inside it and the presence of many enzymes.
