The place where blood clots are most likely to form These are places of narrowing, branching and steep bends of the vessel. The animation shows an example of a bifurcation - splitting a vessel into two branches. Why is the risk of thrombosis higher here? It's because of the turbulent blood flow. Normally blood moves almost like a pathway - with minimal bends and no "obstacles". But here there's a bend and an obstruction in the form of a partition between the branches. Blood ends up "clinging" to the vessel walls, which causes it to accumulate in the place of whirling. -

Cilia are an amazing "tool" of our body These formations are located at many different points in the human body, but they always serve one main function. 👉🏻 They create a wave-like beat. Typically located in large numbers on the surface of cells, cilia create this "wave", which conditions the movement of single cells and the flow of various tissue fluids. And this is how "geographically" varied is the use of ciliums: - they assist in the flow of cerebrospinal fluid in the ventricles of the brain; - assist in the movement of eggs and sperm in the reproductive tract; - push mucus and foreign particles out of the respiratory tract. And those are just three examples! That's how versatile these "cilia" are 🙌🏻 -

The process of ureteral stone crushing☝🏻 The method by which the result in the animation is achieved is transurethral lithotripsy. It consists of crushing the stone with a flexible endoscope tube inserted through the urethra, then the bladder and ureter (where the stone is most often located). There is another option of lithotripsy - remote. Here the stone is crushed with the help of a lithotripter. It is simply placed on the skin, directing ultrasound waves at the stone. Unfortunately, this merciful method is possible only if the size of the stone is less than two cm... -

Bacteriophages are a long-standing candidate to replace antibiotics These are viruses that can kill those that are pathogenic to our body. Their advantage over antibiotics is that bacteria simply cannot "get used to them" by developing resistance. Of course, pharmaceutics "tunes up" bacteriophages in the right way to make targeting more successful. These special viruses are already used in medicine, but only rarely - more often antibiotics are preferred. Why, since bacteriophages are more effective? On the one hand, yes. But their effect is too "exclusive" - many viruses eliminate only a few or even only one variant of bacteria. This complicates their prescription, because the causative agent of infectious disease is not always known🙌🏻 -

And how do vaccines from the muscle "get into the immune system"? This is roughly the wording of the question we heard recently and so we thought this topic needed clarity! The answer is hidden in the animation☝🏻 The drug from the muscle gets into the bloodstream fairly quickly - you don't need more than that to trigger an immune response. Almost every point in the body has an extensive system of lymphatic vessels, which is also indicated in the animation. That means the immune response will also be quite fast! However, not all vaccines are injected into the muscle. Some vaccines, such as the rotavirus vaccine, are given orally. Others are given directly under the skin or subcutaneously - you might think of measles, mumps, and rubella vaccines. The essence is the same. The drug eventually enters the bloodstream in the same way, where the expected immune response occurs. -

Let's look inside our large intestine, shall we? In the animation, we are traveling through it! We see the beautiful pink inner walls of the organ and its characteristic semi-lunar folds. However, further on everything changes and the pink wall becomes kind of unflattering🤔 This is exactly where the colon is affected by Crohn's Disease. Crohn's disease is an inflammatory disease whose exact cause is still unknown to medicine. In the animation we can see its typical manifestations - the mucosa with numerous transverse fissure ulcers is bumpy and has a "cobblestone sidewalk" look ☝🏻 -

Essential organ of immunity, that no longer works even in childhood The thymus is the organ shown in the animation☝🏻 The maturation, differentiation and immunological "training" of T-lymphocytes takes place in it. Why do children have a thymus and then gradually lose it as they get older? This organ is only necessary to create "initial" immunity. To build it up from scratch after birth🙌🏻 During puberty, the body itself deprives the thymus of blood supply, causing its tissue to lose its "immunological" function. Interestingly, some scientists attribute the decrease in immunity to the final disappearance of the thymus, among other things. -

Blood is a liquid form of connective tissue! A paradox of our body's terminology. But why is blood called tissue? Because that's how it's interpreted on the histological level🙌🏻 More than half of blood consists of plasma, and the rest is a suspension of its form elements. Those same red blood cells, white blood cells and platelets. There are other, more specific cells, but their number is disproportionately small compared to the form elements. -

A disease that often develops in athletes Lower limb varicose veins disease is a pathology in which superficial veins dilate and their valve apparatuses stop working adequately. They hold the reverse flow of venous blood less well, due to which it stagnates in the legs. But why do athletes develop varicose veins? Sports are good and beneficial🤔 Well, in the context of varicose veins, it's not that simple. Varicose veins develop in athletes due to high physical loads on the legs, and especially due to jumping - the strong impact load from the landing has a bad effect on the veins. -

Maximum zoom in on our skin! The animation at the end brings us to what the keratinous layer of our body's "shell" looks like☝🏻 That's what makes the skin one of the most intensely renewable organs - it gets rid of about 30,000 dead cells every minute. -

Transport of vesicles into the Golgi apparatus All of this happens inside our cells. The vesicle is the basic tool of the cell. They are inside the cell in great numbers and are responsible for metabolism, storage and transport of substances. The animation captures the moment the vesicles detach from the endoplasmic reticulum and fuse with the nearby Golgi membranes☝🏻 -

The large intestine has romantic feelings, too! There is no other way to explain this figure formed by its slice in the center of this microphotograph☝🏻 The bright purple outline consisting of cells is the wall of the intestine, which creates the cavity inside it. And the strange "bubbles" inside it are the goblet cells (they partially resemble a glass in their shape). Their task is to produce mucus, which facilitates the passage of the food lump, and participates in the digestive process.

The bacterium responsible for helping the body synthesize vitamins And you all know it: E. coli☝🏻 Most of its strains are not only harmless, but also good for our bodies. For example, E. coli helps to synthesize vitamin K, a substance that indirectly, through the synthesis of important proteins, takes part in the process of blood clotting. In addition, we can also say that it helps in the synthesis of a number of B vitamins! That's how useful this bacteria is to us, if we forget about its pathogenic strains. -

Simple surgical manipulation saving lives Tracheostomy is an operation to form an additional opening in the anterior wall of the trachea. The procedure is necessary in cases of airway obstruction (often caused by swelling of the airway or by a foreign body). However, the animation shows mistakes in this procedure🙌🏻 First, the skin was dissected, then the subcutaneous fatty tissue, the muscle was dissected (although usually the fibers are just disconnected), and then the isthmus of the thyroid was crossed! It is almost not done during this manipulation - the isthmus is just pushed downwards. They only cross it if there is a neoplasm in the area that does not allow you to move that part of the thyroid gland. The animation does not show this neoplasm. -

Flatulence is an unpleasant symptom characteristic of many diseases It occurs when the processes of putrefaction and fermentation are activated. They stimulate increased gas production and the subsequent excessive secretion of gas. This can happen with dysbacteriosis, irritable bowel syndrome, cholelithiasis, celiac disease, and... And with a huge number of other pathologies - we will not bore you with their enumeration. By the way, raw vegetables and plenty of bran often lead to flatulence, keep in mind.

What is the difference between arthritis and osteoarthritis? Extremely similar pathologies, but with some critical differences. In both arthritis and osteoarthritis, the joints are affected. However, with arthritis, this lesion involves an inflammatory process that affects other parts of the body as well. Inflammation can be caused by infection, immune system abnormalities, or metabolic disorders. And osteoarthritis is a process that affects only the joints, but destroys them. That is why when arthritis is neglected, only a joint replacement can help a person🙌🏻
