Microscopy technologies of our today's world let us to examine these networks and to see that how these organs talk with each other. It shows us that how internal organs exchanges messages with each other. Many diseases of our modern world that were previously untreatable can now be overcome by observing these networks with the help of developed technologies. Now we have a chance of living better and long life. The point at which we are now is the real time evolution of human species.
Do you know? That, whenever we eat some food how our body know that the food is passed into your gut and ready to digest? When we eat some food and it passed to gut, the cells present in our intestine burst some clouds of molecules towards other cells. These molecules are known as signalling molecules and they are only a hundred thousand of a grain of sand in size. The message they deliver is "Hey, food's here". These messages are telling the entire body that food has been consumed and ready to digest. Carried in the blood streams the message flows throughout the body. Other organs respond to this message in their own way such as in controlling appetite and promoting nutrients absorption
Recent research has so far discovered hundreds of different molecules carrying such messages. Our internal organs are likely to being use these molecules to communicate with each other.
Command center of our body- kidneys
Kidneys, located just above our hips have more significant functions rather than only producing urine. By sending out a number of molecules to our body, they hold a commanding position in our body networks. They are the oxygen managers, Blood managers and nutrient managers of our body. Let us discuss about these with examples
As Oxygen managers
A group of swimmers came to Flagstaff, Arizona, USA that is 2000 meters above the sea level to train their kidneys. Straight after finishing a session the athlete's blood oxygen levels are measured. The normal value of oxygen saturation is 96-99% but their readings are of 80s range. All of those swimmers shocked from these readings. This means that their bodies are suffering from oxygen deficiency. But after two weaks of training now there bodies have plenty of oxygen and their readings are above 95%. This is known as altitude acclimatization.
What type of physiological changes have been taken since these two weeks? Is it the lungs which take in oxygen? Or the heart which pumps it into body? The answer is neither. The athletes are actually temporarily training their kidneys even without realising it. The whole thing occurring here is that when our body suffers from oxygen deficiency our kidneys react to it by releasing some molecules into our body. These molecules are known as Erythropoietin (EPO). It tells to other organs that "We need more oxygen". It's carried out by blood stream throughout the body. So which part of our body reacts to these molecules? These are bones. Bones have holes to allow have blood vessels in bone marrow where the blood is produced. The message molecules tells to those developing red blood cells to multiply faster. These blood cells are the transporters of oxygen and to increase the oxygen level, we need faster and increased transport. With the increase of these transporters now more oxygen can be transported to the muscles it improves the physical endurance of the athlete's body. So during their trainings on higher altitudes, the red blood cell's level increases. In all of us, kidneys are sending messages to our bones to maintain the level of oxygen in our body.
As blood manager
A person was suffering from hypertension. His blood pressure eventually wents to 200 to 110. He used take many types of drugs to maintain their blood pressure,but the didn't work. Conventional medicines were unable to treat it. Persistent hypertension can lead to strokes and heart attacks. Butna revolutionary treatment can now trear it. The doctors did a surgery of his kidney by puting a device into the kidney through an artery of his thigh. By applying the heat from inside the blood vessels, it decreases the over reactivity of the nerves leading to kidneys and cures the hypertension. But how can operating the kidney possibly lower the blood pressure?
Our kidneys releases an another kind of signalling molecule to regulate our blood pressure. The molecule used for this task is called Renin. Renin triggers the contraction of our blood vessels thereby boosting the blood pressure. So our kidneys are fine tuning the renin levels to control our blood pressure in a very precise manner. But it is found in mant hypertension patients that the level of renin secreted by kidneys are very high. Many drugs are already have been developed but their effects are not enough in some cases. But if the neural activities of the kidney can be suppressed surgically, renin levels can decrease which can results in lower blood pressure.
The body's transportation roots, blood vessels are extended throughout our body and makes an conplex network. They transports nutrients, oxygen and waste across our body. They are also used as information circuits and carries signalling molecules. These blood vessels are concentrated around the kidneys and one quater of the pumped blood travels from heart to these kidneys.
As nutrient manager
When we eat food, many nutrients are absorbed into our body through blood vessels including sugar, salt, calcium, magnesium, potassium, phosphorus, uric acid. If these nutrients are imbalanced in our blood, alarming things can happen. Take an example of potassium, banans are rich in potassium and it is an important element for our body. However, if there is too much of it, it can cause irregular heartbeat and could be potentially harmful to life. But if healthier person eat banana, his blood potassium level will not rise to critical levels. And these are kidneys that regulates these levels. They work away constantly and simultaneously fine tuning the many types of chemicals in our blood.
