The places where we sit, the air we breathe, the things we hold are full of germs and viruses, but we are unable to see them. Germs and viruses are small organisms that cause diseases in human beings. We cannot see them with our eyes but they can cause us to become sick and to lose strength.
There are other organisms we are unable to see. These make up the army that lives inside us and protects us against our germ and virus enemies. This army is called the "Immune System".
Our immune system exists within our blood. The cells that make up our immune system are called the white blood cells.
When an enemy enters our body, our blood works just like a laboratory. It immediately produces very special substances to fight the enemy and reproduces more cells matching the enemy's strength. A ferocious battle begins. Sometimes the army in our body wins the battle without us feeling it and the germs and viruses die.
The importance and benefits of vaccination: Dangerous germs are given to the body after being made ineffective. In this way, the immune cells recognise them and take measures to protect you against them.

For us, our heart is an essential organ. It beats about seventy-two times per minute and about forty million times per year. To understand what a tiring activity this is, just make a fist with your hand and then relax it, and continue making a fist and relaxing it. How many minutes do you think you will be able to keep this up? Your heart, which is about the size of your fist, continues this action throughout your life without becoming tired or even stopping once. Our hearts don't stop even while we are asleep. If we become excited, our heart beats faster, and it beats slower while we rest. Our heart makes all these adjustments automatically while we are totally unaware.
Every time our heart beats, it pumps blood around our bodies. What we need to survive is in this blood. Every one of our cells receives the necessary oxygen and food they need from the blood. Our heart pumps about 43,000 litres (approx. 11,000 gallons) of blood per day. Do you know just how much blood this means? This is about enough to fill 150 bathtubs. Wouldn't you become tired if you tried to empty a single bathtub full of water with just a cup? Now imagine having to empty 150 bathtubs of water with just a single cup. Probably you wouldn't have been able to accomplish such a difficult task. However, our heart does such a task and has done so since the day we were born and will continue to do so until the day we die. Moreover, it never takes a break. You, for example, would take a break while doing a difficult chore. You would probably need to lie down, or take a rest, but our hearts don't become tired, because they are essential for our survival. It is small but its task is enormous. This is why God has

God has created our ears perfectly just like our eyes. Imagine a stereo, for instance. Even if you turn on the best of stereos, you hear some crackling and hissing sounds. Radio channels often become mixed up. Right now, don't talk but just listen! Do you hear any hissing? Your ears never produce any. You hear the sounds marvellously clearly. Well don't you think that your ears could also have produced crackling just like stereos? God has created our ears perfectly and we are able to hear the sounds around us without experiencing any distortion.
God has created our ears in such a way that we are unable to hear certain sounds that would disturb us. The blood in our body, for instance, flows very fast and it makes a lot of noise during its circulation. However, our ears do not hear the noise that it makes. Our planet also produces quite a strong noise while it spins. Nevertheless, God has created our ears so ideally that we don't hear this noise. God is very caring towards us. This is the reason why, throughout our lives, He doesn't let us hear noises that will disturb us.
This is why we have to thank God for His benevolence. God has stated the following in a verse in the Qur'an:
"God brought you out of your mothers' wombs knowing nothing at all, and gave you hearing, sight and hearts so that perhaps you would show thanks." (Surat an-Nahl, 78)
