You can cry sorrow, joy, hope, peeling an onion or eating spicy foods. If you look at tears under the microscope, they vary in structure. There are three different types of tears. Basic tears are produced to keep the eyes moist and lubricated. These tears consist of oils, salts, fluids and antibacterial elements.Reflex tears occur when irritated due to foreign particles such as onions, spicy food or sudden exposure to light. Crying tears occur after emotional stress, pain or even pleasure (such as a laughing noise).These are protein-based hormones. Here you will find (microscopic) pictures of the different tears .

Brain receives and processes a lot of sensory information, such as images, smell, touch and taste. Pain also belongs to this sensory information. This can enter from any place of the body. The input and signals are interpreted by the brain as pain, indicating something wrong with you. Yet, it’s not the brain itself that feels the pain. There are no pains in the brain . The pain does not come from your brain, but from the place where the pain is.

In multiple studies , several subjects were shown to subjects. It emerged that it takes our brain some time before these images are received. The most recent research shows that our brain recognizes and receives an image within thirteen milliseconds. But that still means that we live with a little delay.

The blind spot is a common phenomenon in vertebrate animals. The light detecting photoreceptor cells are absent in the area where the optic nerve comes through the retina. As a result, light is not detected in this location and the corresponding field of view becomes invisible. Because our brains are going to fill this blind spot, it seems that they are just visible. In the 17th century, this phenomenon was discovered by Edme Mariotte from France. ( Source )

5. Your brain filters sensory information. For example, you always see your nose, but the brain ignores this

All unnecessary or redundant information your brain receives from the incentives from your environment will be filtered. That is, your daily sensory information, such as blinking your eyes, does not notice the sense of clothes on your body, breathing and swallowing, unless you consciously try to experience them. Neither do you see your nose while it is still in your field of view. All this filtering work is performed by the Thalamus, the area in which the sensory and motor neurons relieve signals and that is also involved in your consciousness.

6. In stress and danger your blood becomes thicker

In the early stages of stress and danger, a number of responses are initiated in our body. This helps us to cope with the situation. In a study, a group of people with anxiety disorder was compared to a group of healthy people. After a blood sample was taken from the subjects, they were asked to do some tests on the computer. In the group of people with anxiety disorder, a much stronger activated clotting system was found in the blood. That is, they had thicker blood. Scientists believe that this is a statement that fearful patients have an increased risk of dying from a heart disease ( no less than three to four times higher ).

The liver is the only body part with regenerative abilities. If your liver is surgically removed or suffering from chemical damage, it will regenerate. That is, it returns to its original state. It is claimed that only 25% of the liver must remain in order to return the liver to its full state. However, a number of criteria have been set for a donation of your liver: You must have a match or similar blood type, you must be between 18 and 60 years of age and be healthy. In fact, regeneration of the liver can not be called real regeneration. The liver can restore its function and mass, but not its original shape. The liver lobes do not grow back. Genuine regeneration of the liver, ie restoration of function, mass and shape, really takes place in lower species, such as a fish. ( Source )

The stomach is the organ that consumes the food you eat. It also has to take care of bacteria and other bad things that enter the stomach. The stomach acid in the stomach consists of hydrochloric acid, potassium chloride and sodium chloride. These substances kill the bacteria and activate the digestive enzymes. It is a very strong acid with a very high pH value (between 1.5 and 3.5). Scientists experimented with razor blades, disc batteries and coins by placing them in a simulated gastric acid juice and looking at how to best drive them if you accidentally swallowed them. They found out that after 24 hours the razors weighed only 63% of their original weight and became fragile. However, the disc batteries and coins turned out to be insensitive to the gastric acid juice. ( Source )

Your body consists of three types of muscles, namely skeleton, heart and smooth muscles. The skeletal muscles can volunteer you to a movement. You use them to make your body move. They are always in pairs and there are about 320 pairs in your body. But because there are different opinions about how they are precisely grouped, the total number of skeletal muscles is somewhere between 640 and 850. Of the type of heart muscles there is only one in your body. The smooth muscles are in your intestines, your urinary tract, your trachea, the iris of your eye, your skin and the lining of your arteries and blood vessels. These muscles function involuntarily and consist of large numbers. The reason we do not know exactly how many muscles our body Has, there are different opinions about what exactly a muscle is called. It is alleged that there are more than 50 billion muscles in a body. But there are also scientists who claim that these are only 656 to 850 (the smooth muscles are not counted).

Already in the early 20th century was discovered by German dermatologist Alfred Blaschko that the structure of the skin of his patients consisted of specific patterns. These did not follow the line of nerves, blood vessels or another physical system. He traced these patterns to the body, but later it was discovered that its amount is much higher than the amount that Blaschko thought to see. These patterns are the result of the formation of new cells on the skin that occurs after body growth. They follow a V-line on the back, a wave motion on the head and a S-line over the chest and they.
