| INTRODUCTION |
The heart gets messages from the body that tell it when to pump more or less blood depending on a person's needs. When we're sleeping, it pumps just enough to provide for the lower amounts of oxygen needed by our bodies at rest. When we're exercising or frightened, the heart pumps faster to get more oxygen to our bodies. The heart has four chambers that are enclosed by thick, muscular walls. It lies between the lungs and just to the left of the middle of the chest cavity. The bottom part of the heart is divided into two chambers called the right and left ventricles (pronounced: ven-trih-kulz), which pump blood out of the heart. A wall called the interventricular septum (pronounced: in-tur-ven-trih-kyoo-lur sep-tum) divides the ventricles.about 2.5 billion times in a 70-year lifetime |
| TASK | In groups of four students, they were investigating the importance of the device cireculatorio 1- That function has the circulatory system. 2- Explain in that conciste the major traffic and minor traffic. 3- Explain in that conciste the lymphatic system. 4- Explain which are the types of traffic that exists. 5- That we can do in order that our this circulatory system in a good condition(state) 6- In that conciste the pulmonary Traffic. 7- In that conciste the Traffic portal. 8- In that conciste the coronary Traffic. 9-In that conciste the beatings of the heart |
| PROCESS |
1-It(He,She) uses the resources that you have available in your house, library, or material of support that is asked you in the college. 2-it(he,she) represents the circulatory system by means of a drawing, also this one represents on all the parts formed the heart. 3-It(He,She) represents by means of a dibuo the pulmonary traffic. 4- by means of a drawing it(he,she) represents the blood glasses. 5-By means of a drawing it(he,she) represents both types of artery that exists, distinguish them with a different color each one. 6-Do a drawing of the heart with his(her,your) different parts(reports) |

| EVALUATION |
To qualify from the 1 to 10 that so guessed right and clear it is the explanation of the student. 1-Write a paragraph of since(as,like) there happens the process of the circulatory system for the whole body. 2-Calificar in the same form the designs requested in the paragraph of procaso. 3-Solicitar to every student that of since(as,like) minimum 4 you design of since(as,like) being kept healthy. 4-Calificar the explanation that of the student of at least 3 of the requested questions. |
| CONCLUSION |
On having finished the topic the children will have a clearer idea in which conciste the circulatory system, which is the traffic of the blood for the whole body. Importance that she(it) has for the life of all the human beings. |
