This term we were all put in groups and asked to do projects on the systems of the human body, the systems were Muscular system, endocrine system, lymphatic system, circulatory system, digestive system, skeletal system, urinary system, nervous system and respiratory system. The requirements were to type up a word document with the following headings: Description, history, future, care and problems. We were also had to make a 3D working model on the system we were assigned to do, work as a team, co-operate and make a power point in a certain amount of time. On each presentation we were asked to take notes about each system.
Muscular System: Muscles are very important in the body because they move. Cardiac muscle is a muscle in the heart. Muscles can vary in size throughout the body. Muscles contract and relax when you move.
Endocrine System: Hormones send messages throughout the body. A target cell can only be a target cell if it has a receptor. There are many problems in the endocrine system. The endocrine system consists of lots of different hormones. Claude Bernard was the first ever person to state the description of the endocrine system.
Lymphatic system: The lymphatic system was discovered by Dr Gaspard Asseli in 1662. The lymphatic system is a network of tissues and different organs like tonsils. You can easily get rid of tonsils if they get too big for you. If you laugh and meditate you are taking care of the lymphatic system. All the lymph nodes inside your body are green.
Circulatory system: The heart is a vital muscle that pumps blood through your body. William Harvey first described the circulatory system in 1616. If there is a blockage in the coronary arteries it causes a heart attack. Blood is made of red and white blood cells. Marrow in bones makes white blood cells. Veins are less flexible than arteries.
Digestive system: a diesis the pancreas can have is diabetes. The small intestine is 6 meters long which is longer than the large intestine. The large intestine gathers vitamins. The large intestine takes about 16 hours to digest food. Eat good food like vegetables and grains to take care of the digestive system. Saliva makes it easier for food to go down the oesophagus.
Skeletal system: There are 206 bones in an adults body. You can take care of your bones by drinking/eating calcium and exercising which makes the joints move more freely. They used to use bones for useful things such as handles for knives, forks and spoons they also used them for flutes.
Urinary System: Urine is a clear yellow substance containing unwanted wast. The kidneys are red and brown. The bladder contains the urine after it’s been through the kidneys. Roman spies used urine as invisible ink. You can live without one kidney because you only need one.
Nervous system: The nervous system includes the brain, spinal cord and nerve cells. You couldn’t live without the nervous system. If you damage your spine you will feel lots of agonizing pain. Epilepsy is a diesis that causes sudden jolts and staring blankly.
Respiratory system: Lungs are a red and brown organ that helps with breathing. If you breathe in dirty air the respiratory system filters out the bad molecules. Lung cancer is cause by smoking because of all the tar. Scientists are thinking about making replacement lungs with 3D printers. Asthma is caused by the trachea blocking up.
I learnt a lot during all of these presentations they all had lots of good information and good 3D models. While taking these notes I have built on my knowledge of the human body and can now give facts about each system with no hesitation at all. I also think I worked well as a group member and I feel we had a good amount of information and a good demonstration of the hinge joint for our 3D model.
