How important is water to us? After Reading the journey of water in the human body, you will understand

Function: moisturizing. Take a sip of water, which is involved in the digestion process as soon as it enters the mouth. Water mixes with saliva secreted by the salivary glands to aid swallowing. Once swallowed, water passes through the esophagus into the stomach. The esophagus is a muscular tube that connects the mouth to the stomach. The muscles contract rhythmically, causing the esophagus to peristalsis, gradually pushing water and food into the stomach.

Function: moisturize. Drinking more water can nourish the lungs. Sufficient water can keep the tracheal mucosa moisturized, make people feel breathing smoothly, and the lack of water can easily make your body have dry cough, dry skin, dry mouth and other symptoms.

Function: dilutes, dissolves, relieves dry mouth, cough, dry skin and other symptoms. Water stays in the stomach for a short time, and unlike food, water does not need to be broken down further. Some of the water quickly enters the bloodstream through the stomach lining (so you will feel thirsty immediately after drinking water). The stomach also mixes water with gastric juices to dilute and transport nutrients. In addition, water can help you dilute the concentration of stomach contents, such as alcohol.

Function: stimulate the peristalsis of the intestine and promote bowel movements. Ensure the normal operation of intestinal bacteria. The main part of water absorption is the small intestine. Here, water from the small intestine is absorbed into the bloodstream through the intestinal wall. Absorption is achieved through the osmotic process. The osmosis process is very important for life, animals, plants, microorganisms cannot do without it. Water is a solution, and the substances in the solution are called solutes. Put the solution with less solute and the solution with more solute together, and separate it with an osmotic membrane, then the solution with less solute will pass through the permeable membrane and flow to the side with more solute until equilibrium. Drinking plenty of water stimulates intestinal motility and softens stool. In addition, a large amount of sufficient water can also ensure the health of the intestines and the normal operation of the flora, and carry out normal work.

Function: follow the blood circulation into all parts of the body, playing a role in moisturizing, transporting, excreting and other functions. The nutrients needed by the body are circulated to various parts of the body with water. Water can also be excreted through the skin in the form of sweat, helping the body metabolize waste.

The function of the brain: transporting essential substances such as oxygen. When the human body is dehydrated, the nervous system is abnormally active in the process of adjusting the water ratio, and when it is reflected in the cranial nerves, they will stimulate the pain nerves.

Function: lubrication to reduce friction in the joints. During exercise, the fluid in the joint cavity ensures that the bones slide freely and smoothly, reducing frictional resistance and preventing damage to bones and joints.

Function: transport nutrients and oxygen, maintain normal body temperature, and slim down. Water is like a postman, after sending nutrients into the cells, it can take out the garbage in the cells and hand them over to the kidneys for processing. Drinking more water when you have a cold and fever can promote the body to dissipate heat and help the patient restore normal body temperature.

Function: filtration and excretion. The kidneys are a very important part. Blood carries waste products produced during cell metabolism to the kidneys, where they filter and remove excess water, waste, and electrolytes to form urine. It ensures that the body retains the necessary water and electrolytes, eliminates the rest, and ensures the stability of the environment in the human body.

Function: excretion. Urine formed by the kidneys is stored in the bladder. When the bladder is full, nerve signals are sent to trigger the desire to urinate, allowing the body to expel urine. The body's metabolism is going on all the time, so we need to drink water often and urinate often. The journey of a glass of water inside the human body is amazing. At the same time, it also highlights the importance of water to the human body. From hydrating and aiding digestion and absorption to maintaining cellular function and removing waste, water is essential and essential at every stage. "Medicine is not as good as food supplement, food is not as good as water supplement" should become a new health concept. "People put water first" can be compared with "people take food as the sky".
