  • How exactly is water being absorbed in the body?

    Are you interested in understanding the journey of water absorption in the body? Looking out for answers here? On this page ISC experts shall provide you with answers regarding this question here.

    Stomach, other than storing food, stores water too temporarily. Stomach is lined by mucous and is filled with acid when we eat or drink. Doesn't water we consume react with these components?
    Water is finally absorbed in small intestines. But how is it transported to cells? Through blood? Can someone kindly guide me about the journey of water inside a human body?

  • Our digestive process is very unique and interesting and is the main thing from which the basic raw material converted to smaller form is received in the body for providing energy and material to the various parts of the body. First of all whatever we eat is all mixed up in the stomach and with the motion of alimentary canal it is slowly disintegrated in the smaller parts and finally a paste type thing is made out of it and in this process the water works like a lubricant, solvent and a base for all the food items to move and interact with each other in presence of the various chemicals, acids and bacteria and enzymes in the stomach. Due to the forwarding motion of the alimentary canal the food paste slowly moves from stomach to the smaller intestine and then finally to the bigger intestine and then finally the unused and unwanted parts are secreted out of the bigger intestine through the rectum.

    The interesting thing in this process to note is that the paste which is formed can be dense or lighter depending on the quantity of water we take with food or after food. Now the lining of the stomach and intestines have a mechanism of absorbing the various nutrients, essential chemicals and energy from food particles in their final broken down stage and everything that is absorbed goes to the blood. Here I want to clarify that absorption will be at microscopic levels and only chemicals including nutrients and water derived from food will be entering the blood stream. No solid particles can travel across the inner lining of the stomach or intestine. So after the food is converted in a paste all the chemicals and compounds in microscopic levels will get absorbed and will go in the blood. It is the blood which does the work of taking it to other places in the body.

    Now, blood is going everywhere in the body and it will deliver the required chemicals and other things like sugar, protein, antioxidants, vitamins etc to each and every part of the body as it is required there and the balance extra will be filtered out from the kidneys and rejected through the urinal bladder. We take the food as solid but inside the body everything is transported by blood as dissolved chemical and nutritive things. If we eat too much of fat then body will start depositing it in our tissues and our belly will start coming out and our other body parts will also become fatter.

    So please note that it is not the water that is moving in the body. All sort of food converted to other forms like protein, sugar and vitamins etc along with the water will be going to blood and it is a continuous process. Water is almost a inseparable part during this journey and will be utilised along with other nutrients. Blood is delivered to every organ and every organ has a specific job in the body and the outgoing blood will have the signature of that work done in that part. That is why the doctors test our blood for our diagnosis as contents of the blood will tell what is happening where. Body has a great mechanism of removing toxins and poisonous things from the blood and they are excreted from the body in stool and urine. If a small mechanism fail in the body the presence of the unwanted chemical will make a person ill. Our body is a complex biochemical machine of a very advanced nature and science is still pursuing many researches to understand it fully.

    Knowledge is power.

  • Water's journey in our body starts from the mouth. After drinking some water our brain sends signals that the water we have taken is sufficient. The water will take a long time to provide enough hydration to cells. If the brain is not giving us an indication well in advance we may be consuming more water than required. That is why our brain will send the signal in advance. Starting from mouth water travels through the esophagus and reach our stomach. Now the process of water absorption into the blood stream will start. The water absorption process will be fast if you drink water on a empty stomach. If you take water after taking food it may take more time for water absorption.

    A majority of water's absorption takes place only while it passes through the small intestine. From here, water will get into cells across the body. This will provide hydration so that they can perform well. Once the absorption is over it has many functions to do.

    Water will help Kidneys in filtering toxins. If we don't drink sufficient water the load on the kidneys will increase in filtration. This will result in various problems of health related to Kidney. If the load is more on the kidneys and if you are not drinking sufficient water the urine color will change to yellow. It is an indication that your water intake is less.

    Water is sent to brain also.It will provides hydration to brain cells and useful in maintaining some cerebral functions.

    The excess water consumed will be sent out mainly in the form of urine with the removed toxins. Another way is with our motion. Our motion contains 25% solids and 75% water. It will help in good motion and no constipation.

    The skin will also use up water to maintain the body temperature. When the temperature outside high or when you are doing some physical work the skin sends some water droplets through the skin which keeps our body in the correct range of temperature,

    always confident

  • Once water passes through the stomach and later on the small intestine, most of the water consumed passes through the blood stream. The small intestine having its length approximately 20 ft long, efficiently absorbs the water into the cell membrane and blood - stream. Once absorbed in the body, the water helps in a number of vital functions.
    In fact, our consumption of water is not up to the desired level often consuming less than a litre. Hence under that condition removal of toxins from the system is affected substantially.
    There exists a difference between eating food and the drinking water. Once the food is consumed, it is digested where as water is absorbed into the body - system.
    The journey of water begins in the mouth and the first major step noticeable is the hydration. After a few gulps of water, the brain provided signal whether whether the intake of water is sufficient or not. The communication between the brain and mouth allows someone to stop drinking at the appropriate time, even if the water is not fully hydrated the entire system.
    From there it passes through the stomach by means of esophagus - a small pipe connected to the mouth and the land of stomach. The rate of absorption of water will depend upon the state of stomach ie empty or full. In the empty state, the rate of absorption will be faster as compared to full stomach. The small intestine efficiently absorbs water into the cell membrane and blood stream. The journey of water does not stop there . It will strengthen the functioning of the entire vital organs.
    One such task is to filter toxins due to abundant presence of water. Of course, it is the task of kidney to expel the toxins. However, removal of toxins is expedited due to proper intake of water. Whether the intake is sufficient or not can be gauged through the colouration of the urine. Yellow colour would indicate less consumption of water and less intake of water may cause stone formation of kidney apart from dehydration. Dehydration may cause elevation of serum Creatinine a disorder of kidney - function.
    Excess water is removed through urine and its exit point also through the rectum where stool passes in the soft state because of hydration of the body due to proper intake of water.
    Small droplets of water also exit from the body via breadth. It can be seen during the days of winter when one can see the vaporisation of water iminating from the mouth.
