This term our topic was all about the body. Every one had to do a group project about a system. My group and I did it on the Nervous System. We researched then made a presentation to the class. I think that we went really well. While each group was presenting every one else had to take notes. They were going very fast so I found it easier to just write key works. After the presentation we could ask questions if we needed to then with our key notes we had to write a summary or a information text about it. Here are mine:
The Circulatory System
The Circulatory System consists of the Heart, Blood, Veins, Capillaries and Arteries. There are 2 smaller systems among The Circulatory System. Blood is made out of plasma, white blood cells, platelets and red blood cells. If you get a bruise, the colour of the blood beneath changes colour over time. The Circulatory System is related to The Respiratory System. They are much alike. There are approximately 5 million red blood cells in a small drop of blood. Your heart beats 100 000 times a day [around about].
The Muscular System
In The Muscular System triceps and biceps work together. They help bend and straighten your bones. Your Pectorial and your Gluteal are 2 muscles. Muscle cells and filaments provide protein for your body. If you have the correct posture when sitting it will help your muscular system. If you have a torn muscle some ways to treat it are to rest the muscle, put some ice on it and compress the area. In the future scientists might make artificial nerve cells. They will be better then the ones we have. The strongest muscle in your heart is the heart. There are muscle under strands of hair. If you pull out a strand of hair the muscle will die then regrow.
The Immune System
The Immune System was discovered over many years. ‘Immune’ means to be protected. The Immune System fights bad colds, bad virus and keeps our body healthy. Your tonsils are the things that fight throat infections. If we did not have the Immune System if you got a common cold you would get very ill and die. Some people have to live in bubbles if they don’t have there Immune System. If you get bacteria from someone else it will not multiplie and the white blood cells will eat it up. Some ways to keep your Immune System healthy are low fat diets, exercise, vitamin A, low stress and good rest. You can get some cancer if you don’t take care of your Immune System.
The Lymphatic System
Thomas Bartholin discovered the Lymphatic System in 1652 and died in 1680. The Lymphatic System sends Lymph around the body through vessels. Lymph is like white blood cells. To help your Lymphatic System you should move around a lot, do Yoga or Meditation and eat healthy food. If you did not have your Lymphatic System you would get large swelling and if you got a mild cold, you would probably die. A disease of the Lymphatic System is Lymphoma and doctors are trying to find a 100% cure to Lymphoma.
The Respiratory System
Mr Hooke was the main person who discovered the Respiratory System and it was discovered over many years. Some of the diseases of the Respiratory System are asthma, breathlessness and wheezy. Some ways to help are if you have asthma don’t run around to much other wise it may be hard to breath. If you have lung cancer don’t smoke. In the future scientists may be able to grow body parts as well as parts in the Respiratory System. The Respiratory is all about breathing and your lungs. mouth, nose, trachea and diaphragm.
The Digestive System
The Digestive System breaks down food and makes it into energy. Some diseases are appendicitis and diabetes type 1. William Beaumont discovered acid in the stomach . He got a piece of string with some chicken on it and placed it down a person. Lots of people discovered it over time as well. The Digestive System helps you eat and drink. Soliver breaks down chemicals. It also sends messages to the stomach to say that food is coming or that your thinking about food then you tummy will probably grumble. One part of the Digestive System is the Oesophagus which moves food down through a tube sort of thing. Another one is the Small Intestine which is 6.7m long and breaks down food into energy. To help your Digestive System eat healthy food. Without your Digestive System you would have no nutrience and you would not be healthy at all. Scientists are trying to make a drug that makes the Digestive System go 2 hours faster.
The Skeletal System
In the body we have 206 bones and a baby has 305. A baby has more because as it grows its bone start to connect to make bigger bones so there are less. Most of the bone names came from the languages Latin and Greek. The Skeletal System was discovered over time. Bones are tough but they can break and get diseases. If we did not have the skeletal System and we did not have any bones we would be a puddle on the floor. In the future scientists might make bionic bones. If you have vitamin D and calcium it will help your bones. Your smallest bone is your Stirrup.
The Urinary System
600 years ago Andreas Vesalia discovered the Urinary System. The Urinary System filters waste and makes Urine. You can have 1 kidney and we alive. Smokers have a big chance of have a Kidney Transplant. If you have a kidney failure you need to have you kidneys replaced. The parts of the Urinary System are the kidneys, ureter , bladder, sphincter and the urethra.
