"A system is more than the sum of its part, it is an individual whole. It loses its essential properties when it is taken apart. The element of a system may be apart of a larger system"

Dr.Russsell Ackoff

 

Respiratory System :

 

Respiratory system is a system in all living things' body, through which oxygen and carbon dioxide are going to be exchanged between the organism's body and its surrounding. Different structures have the function of gas exchange such as lungs, gills, and spiracles. After the entrance of the gas to the body, gas(mainly oxygen) should be carried to all body organs/cells, and waste gas (carbon dioxide) should be carried away from the body organs/cells and be excreted. These two gases should be carried by the blood by the aid of circulatory system. The circulatory system can be can be either open or closed circulatory system.This unit will include KWL, STAD, Think-pair-share, and Think-pair-square activities that will enhance motivation and promote higher thinking skills

Task

20150508021048uhezy.jpg

In this unit we are going to:

1- role play to observe inhalation and exhalation

2- dissect fish to observe gills

3- collect insects to observe spiracles

4-watch videos about sponge to see diffusion process

5- draw a table to differentiate between gas exchange structures

6- build up lung model

7- build up heart model to observe the closed circulatory system

Evaluation

Conclusion

Each day we breathe about 20,000 times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, trachea, diaphram and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air.

It is important for everyone to know at least the basics of the Respiratory System. It will help individuals understand their body more and how to take care of it too its fullest.
