The liver is the largest organ in the body. It stretches across the whole per part of the abdomen and is protected by the lower ribs, so that when something hits the area, the liver usually escapes injury. Most everybody seen slices of calf’s liver. Our livers is much the same-soft, reddish and meaty. Of course, our livers not sliced.
The liver serves as a powerhouse, a chemical factory, and a warehouse. It a powerhouse because it produces
proteins that are necessary to for blood cells and to supply our tissues with on. Another function of the liver is to form bile, which flows into the intestines and allows us to digest the fats that we have eaten. The liver is a warehouse because it stores fats and proteins and sugars, and releases them into the bloodstream when we need energy for our daily activities, or when we need substances to replace used¬up materials. The liver is so important that without it we cannot live.
The liver does even more than what we have just mentioned. Like a huge chemical factory, it performs the following functions:
The portal vein collects blood from the intestines and takes it to the liver. Through this vein, food elements which have been absorbed from the intestines are brought to the liver, where their nourishing ingredients are taken out.
1. It forms chemicals necessary for blood clotting. If we had no liver and cut ourselves, we would continue to bleed and bleed without stopping.
2. It also forms chemicals that prevent too much blood clotting. If we had no liver, the blood in our arteries and veins, instead of flowing smoothly, might clot and not run at all.
3. It purifies the blood, getting rid of waste materials.
4. If a poison should accidentally get into the body, the liver will destroy and get rid of it.
The liver receives most of its blood from the intestines. When the nourishing foods and vitamins we have eaten are absorbed through the walls of our stomach and intestines, they go directly into vessels that lead to the liver. In that way, the liver receives all the fats and proteins and sugar and minerals and vitamins that we have digested. The liver is such a remarkable organ because it can do its job even when it is inflamed or damaged. In some sicknesses, a large part of the liver may be out of order, yet the remaining part will keep us going until recovery takes place. Of course, we must be sure that we don’t cause damage to our liver. For instance, here are some rules to hell) keep your liver in good condition.
1. Avoid as many infections as possible, because germs and viruses can easily reach the liver and inflame it. When you are told to take medicines, take them without making a fuss. Then the chances of a liver infection will
not be very great.
2. Avoid eating or drinking anything unless it is approved by your parents or other grown-ups. Some children accidentally swallow harmful substances that might poison their liver. It is particularly important to keep things like cleaning fluids and detergents and insect killers and antiseptics and drugs away from small children. They don’t know any better, and they may think they are good to eat or drink.
3. To work properly, the liver needs a large supply of minerals and vitamins, as well as a good supply of fats and proteins and sugar. This means that a child must follow a good diet at all times. It won’t help a child’s liver if he balks when told to eat fruits and vegetables, or fails to drink plenty of milk. And if his doctor wants him to take vitamins, he should take them without squawking.
