Week 9 revision Task

This week and last week we have been doing report writing we had three topics to chose from but you only had to do two of them me and my buddy jimmy done eyes and the heart here is our heart work below

The heart is an organ in the human body. It is used to pump blood around the body. Without this organ, you will have a hard time living. This body part is essential because without you would not be able to pump blood.

The heart has lots of different parts for pumping blood around the body. It has four main parts called the Right Atrium, Left Atrium, Right Ventricle and the Left Ventricle. They all are pushed by powerful muscles and are filled with blood to pump around the body. The blood travels through the arteries to different parts of the body. The blood takes oxygen and other important things to the Brain, Eyes, Legs, Hands, Face and many more parts of the body. The heart needs to pump blood to the muscles that pump the heart!!Illustration of the human heart



Because the Heart is so complicated, it is vulnerable to lots of different problems and diseases. Some of these are:
  • Heart Attack
  • Stroke
  • Hole in Heart
  • Cardiac Arrest
A heart attack is caused by the arteries clogging up and then the blood is not able to flow. This is a serious problem for the heart.
A Stroke is caused by when part of the brain does not get blood because a clot in the artery by blood then bursts the artery. Where the blood is missing, some brain cells die and some of the brain may be damaged permanently.
A hole in the heart is caused in birth but can be cured when you are young but some lucky people have been treated when they are older. The blood that is high in oxygen mixes with the low oxygen blood. As well, if you have a hole in the heart you cannot go on airplanes because of the pressure.
A cardiac arrest is like heart attack but instead of the arteries being blocked the heart just simply fails. If this happens, you can use your favorite toy the… DEFIBRILLATOR. The defibrillator shocks the heart into beating and to giving life to the victim. But this process does not always work.

The heart is a delicate, important organ and it is compulsory to have. Because of this, it is important to look after your heart. To look after your heart, do not smoke or drink dangerous liquids and (If you're under 18) no alcohol. Do not use these things to protect your heart.
