THE HUMAN BODY

Source
good pm hivers it your lover @jayblak. today we would be talking about the human body. the human body is made up of different parts. examples are nose, ears, month, tongue, legs, lungs, ribs, teeth, ans so on. these body parts form the body organs.

collections of organs are called systems. these systems helps us to carry out life processes. thus we have the respiratory system for breathing, digestive system for digesting food, the excretory system for removing wastes from the body and the circulatory system for circulation of blood to all the body parts.

THE RESPIRATORY SYSTEM
We need air to live. the part of air we breathe in is called oxygen.due to what happened to me some weeks back make me go in search of this topic to write about it. the part of air we breath out is CARBON DIOXIDE.

Inside our body, oxygen burns the food to give us energy. at the same time carbon dioxide and water are formed. this process is called RESPIRATION according to what i was taught in my school days. i new this formula when i was still doing primary sicence in my junior class then which goes thus; FOOD+OXYGEN=WATER+CARBONDIOXIDE+ENERGY. this energy given out is used for body activities such as walking, running, reading and many more. the respiratory system consists of the nose, the trachea or windpipe and the lungs.

THANKS FOR REVIEWING MY POST LOVE YOU ALL.
