What are the Five Senses The Human Body for Kids
Sense organs are specially developed parts of your body.
For example, each of your eyes has a retina for detecting light.
And each of your ears has a cochlea for detecting sounds.
These senses send information to the brain.
There are special parts in the brain that sort out this information.
It is then passed to other parts of the brain, which can compare information from different sense organs. Your brain then signals what you are:
These five senses allow you to know what is in your physical environment.
These senses control the timing and movement of food through your body.
They measure the amount of sugar and salt in your blood.
They regulate the amount of oxygen that’s taken in.
Your body temperature and the fullness of your bladder are also under the control of these senses.
Without your awareness, your body is always receiving messages from your hidden senses.
They keep all these basic processes, such as breathing and digestion, running smoothly.

Can you name the “five senses”?
Try to name them before reading further.These senses send information to the brain.
There are special parts in the brain that sort out this information.
It is then passed to other parts of the brain, which can compare information from different sense organs. Your brain then signals what you are:
- seeing,
- hearing,
- smelling,
- tasting, and
- touching.

The hidden senses
Another set of senses, of which you are unaware of most of the time, helps control your inner organs.These senses control the timing and movement of food through your body.
They measure the amount of sugar and salt in your blood.
They regulate the amount of oxygen that’s taken in.
Your body temperature and the fullness of your bladder are also under the control of these senses.
Without your awareness, your body is always receiving messages from your hidden senses.

What is Down Syndrome
What is Down Syndrome?
Down syndrome (DS), also called Trisomy 21, is a condition in which extra genetic material causes delays in the way a child develops, both mentally and physically. It affects about 1 in every 800 babies.
The physical features and medical problems associated with Down syndrome can vary widely from child to child. While some kids with DS need a lot of medical attention, others lead healthy lives.
Though Down syndrome cant be prevented, it can be detected before a child is born. The health problems that can go along with DS can be treated, and there are many resources within communities to help kids and their families who are living with the condition.
What Causes It?
Normally, at the time of conception a baby inherits genetic information from its parents in the form of 46 chromosomes: 23 from the mother and 23 from the father. In most cases of Down syndrome, a child gets an extra chromosome 21 — for a total of 47 chromosomes instead of 46. Its this extra genetic material that causes the physical features and developmental delays associated with DS.
Although no one knows for sure why DS occurs and theres no way to prevent the chromosomal error that causes it, scientists do know that women age 35 and older have a significantly higher risk of having a child with the condition. At age 30, for example, a woman has about a 1 in 900 chance of conceiving a child with DS. Those odds increase to about 1 in 350 by age 35. By 40 the risk rises to about 1 in 100.
