    Duodenum - what is it and why do we need it? Why is this small (20-25 cm) interval of the intestine given a special name? Because it has a special purpose✔️ The duodenum is connected to the pancreas and gallbladder, where a special secret is produced. This connection occurs due to the ducts with this secret that exit into the intestinal cavity through small "papillae". Bile from the gallbladder emulsifies fats - separates large fat droplets into smaller ones to facilitate their digestion. The secretion from the pancreas also contains enzymes that process proteins, fats, and carbohydrates.

    Pleural puncture A procedure that is performed for hydrothorax is an accumulation of fluid in the pleural cavity (between the pleural leaflets). Normally there is only a few milliliters of fluid between them, which acts as a lubricant. But with hydrothorax there may be more than two liters of fluid in the pleural cavity! The most common causes of this pathology are heart failure, kidney disease and cirrhosis of the liver.

    Skin and nervous system are twins You may ask, what are these strange conclusions? These are the canons by which the human body develops🙌🏻 During embryogenesis, both the nervous system and the future skin are formed from a single germ layer, the ectoderm. In addition, the sensory organs, the epithelium of the anterior and posterior parts of the digestive system, and dental enamel are formed from the ectoderm.

    "The skin breathes” Ever heard that phrase? Well, it's not just a figure of speech. Under normal conditions, atmospheric oxygen can supply the upper layers of the skin to a depth of 0.25-0.40 mm! For this reason, there are almost no vessels in the epidermis (although oxygen can "reach" the upper layers of the dermis). An identical mechanism of oxygen delivery exists in the cornea (it also has no vessels and is directly fed). This mechanism is possible due to the diffusive properties of oxygen.

    Why is our brain divided into two hemispheres? Don't rush to the answer: "The left side of the brain is responsible for logic and the right side is responsible for emotions. This is only partially true. We cannot speak about absolute domination of one of hemispheres in logic or emotions. The two halves of the brain are practically identical in structure, and for this reason we can only speak of relative superiority. A more practical and long time scientifically proven reason for the division of the brain is as follows👇🏻 The right hemisphere is responsible for movement and sensitivity of the left half of the body, the left hemisphere for the right half. The "halves" are united by the corpus callosum, which builds associative connections between the hemispheres.

    How often do you think the heart should be "pumped" during CPR? We remind you that a normal heart rate is considered to be 60-90 per minute. Accordingly, it would be reasonable to assume that chest compressions (pumping) should be performed at this rate. However, no. Emergency physicians would say "pump as fast as you can." Because the recommended frequency of compressions is considered 100-120 per minute. That is, almost twice a second you have to push on the sternum, lowering it by 5 to 6 centimeters. This requires very serious physical training, because resuscitation can last more than one minute☝🏻

    Why is there two bones in the shin? No, it's just a nice animation-we're not suggesting that one of them be "removed"😁 Why does the tibia and fibula have two bones in the tibia? There's just one bone in the hip and that's fine. Where is the physiological and anatomical point here? The point is that our ankle is a very complex structure. The tarsal (the same as the wrist, only in the foot) has 7 bones that interact with the 5 bones of the metatarsal, which in turn are connected to the 14 phalangeal bones. Such a complex structure is physiologically impossible to be flexible when connected to only one bone. Otherwise, we would walk like tin soldiers (at best😁) That's why we have two bones in the tibia, and with them a structurally complex musculo-ligamentous apparatus. By the way, exactly for the same reason, there are also two bones in the forearm☝🏻

    Well, why does our body need a fever at all? After all, it's not so much bacteria that triggers its growth as our immune system. Special substances - pyrogens - are involved in this process. Their release is stimulated by the immune system, which thus reacts to the inflammatory process. Which is most often caused by bacteria or viruses. And the pathogen itself can also produce pyrogens☝🏻 Of great importance in temperature regulation is a small endocrine organ in the brain, the hypothalamus. It controls the temperature balance point, which pyrogens shift in the direction of reducing heat output and increasing its formation inside the body. What is the actual purpose of increasing the temperature? Under such conditions the immune system cells work more efficiently and the activity of bacteria and viruses decreases✔️

    The brain generates 25,000 to 50,000 thoughts a day. And it is estimated that most people have 70% of these thoughts are negative. Therefore, it is imperative to tune into something important and productive in this flow. It's necessary to create promising conditions for the emergence of these positive thoughts.

    Is it true that people "fade away" as they age? Well, if you change the way the question is posed, the answer becomes obvious. Do people become leaner as they age? And here you can answer for us, because everyone knows that older people do lose height. After the age of 40, a person "shrinks" every decade by 2.5-7 cm. But sometimes the situation can go beyond that. But why does a person's height decrease in old age? There are several reasons for this. - Loss of muscle mass and fat reserves (specifically this does not always happen). - Osteoporosis. - Thinning of the foot. - Dehydration of the discs (they are between the vertebrae) - this is demonstrated in the picture above.

    Every minute 3/4 of a liter of blood flows through the vessels of the brain, and the total length of all hemispheric vessels is 560 km.

    A little bit of mathematical statistics Our body consists of about 100 trillion cells (of course, the figure is very relative). The brain can be considered the most "cellular" organ - it contains about 14 billion cells. But the greatest contribution to these "trillions" was not the brain. Approximately 95% of all human cells are bacteria. Perhaps this fact gives fertile ground about the "essence of man"👌🏻

    Migraine and its origins? Hopefully, our subscribers are not familiar with the pain that accompanies it... Migraine is a form of headache that is characterized by severe attacks. The pain is characterized only in one half of the head (left or right). It may last from a few minutes to several days. Besides the familiar headache symptoms, migraine may be accompanied by photophobia and loud noises. Therefore, the person is looking for a quiet and dark place☝🏻 No unambiguous and reliable cause exists. However, there was one unusual theory that migraine "affects" people with higher intelligence.
