What is a Human body?

 

 

A Human body is a structure that has internal and external

 

organs are the organs which are inside our body and the

 

organs which we couldn't see.External organs are

 

the organs which are out of all the internal organs and

 

the organs which we could see. We have many body

 

systems in our body,and for the body systems to work, we

 

need the organs in our body.So,each body system has

 

a few organs in them.

Function of Human body systems

 

Function of Human body system means, How does Human

 

body system work. We know that there are a few organs in

 

each body system in our body. Each system in our body

 

will take care of one thing, and to finish that thing they are

 

take caring about, they use the organs, and by using the

 

organs,they make a process to finish the thing they are

 

take caring about. They don't take care of a thing like a toy

 

or something like that, they take care of our breathing

 

and digesting our food and something like that. If even a

 

single system won't work in our body, then we'll not be

 

alive.

Example:Function of Excretory system

 

Excretory system-The  Excretory system takes out the waste

 

out of our body.(Waste liquid). The parts of the Excretory

 

system are,the kidneys,the ureters, the urinary bladder and the

 

urethra So,when we drink water or juice or any kind of liquid,

 

The liquid goes into our body, but the urine(waste liquid)goes

 

into the kidneys. The kidneys will filter the blood and send the

 

urine through the ureters to the urinary bladder. After the urinary

 

bladder is full of urine,then we feel to go to the washroom. After

 

we go to the washroom,the urine goes out of our body through

 

the urethra. This is how the excretory system works or

 

functions.

 

                                   

 

 

 

 

Interdependence of body systems

 

 

Interdependence of body systems means, two or more

 

than two systems working together or depending on each

 

other. Systems working together can also make organs

 

working together. While one system is working, then

 

from that system whatever is useful to the ohter system

 

the system will send it to the other system, then the other

 

system will start functioning. If even one system won't

 

work in our body, then the other systems won't work also,

 

and if the other systems won't work in our body, our body

 

will have a problem or, we will not be alive.

Example:Interdependence of Respiratory, and Circulatory system

 The Respiratory and Circulatory system Interdepened on each

 

other. The parts of the Respiratory system that are used in this

 

are,the nose,trachea and lungs. The parts of the Circulatory

 

system that are used in this are, the Heart, the areteries and

 

veins. So First,when we breath in, the oxygen goes from

 

the nose through the trachea to the lungs. Then, the oxygen

 

goes from the lungs to the Heart. After that happens, then

 

only the Heart could pump the blood throughout our body.

 

The Heart dosen't pump the blood directly thrughout our

 

body, it pumps the blood throughout our body through

 

the arteries. The arteries are thin tubes in our body. If

 

there is any waste blood in our body, then the veins send

 

the blood back to the Heart. The veins are also thin tubes in our

 

body.

 

 

Ways to keep our body strong and healthy

To keep our body strong and healthy, we have to excercise

 

regularly, eat healthy food, have a balanced diet, see TV for

 

 only 2 hours or 1 hour, don't eat junk food, and do many

 

more other things. We have to eat healthy food like

 

vegetables, fruits, minerals,carbohydrates and etc. A

 

balanced diet means eating the right amount of food.

 

If we have a balanced diet, then every thing will be

 

correct and we won't have a stomachache or teeth ache.

 

We should see TV for only 2 hours or one hour because,

 

our eyes will have a problem or we'll become obese. We

 

shouldn't also eat meals while seeing TV. Eating junk

 

food is not okay for our body at all. If we eat junk food,

 

then we'll become obese or we'll have a stomachache or

 

teethache. So, we should eat more healthy food than junk food.
