During term two our class broke up into groups of three and studied a human body system. While they were presenting there final work on their system we took lots of notes, mainly key words or phrases and then turned the information into summaries of the body system. Here are my summaries:
The Nervous System:
The Nervous System is made up of the Central Nervous System and the Peripheral Nervous System. The Central Nervous System is made up by the brain, spinal cord with neurons that send messages to and from the brain along the spinal cord, these messages travel at about 800kph! The Peripheral Nervous System is where messages sent from the brain go along the spinal cord then branch out to other areas of the body to deliver the message. In 1681, the study of Neurology started but today scientists still don’t know everything about the system. Strokes can affect the Nervous System and they make you unable to talk, write and read. Having processed or pre-papered food is not good for the system and if you have poor nutrition you could have a Nervous breakdown. Amazingly, the left side part of the brain controls the right side of your body and the right side of your brain controls the left side of your body! The right side of the brain is better at music and the arts while the left is better at writing and speaking. In the future scientists want to make and improve medicines and create artificial nerve cells.
The Muscular System:
The Muscular System is the system of all the muscles, like all the 650 muscles in our body. Our biceps and triceps are skelatul muscles and they help us to bend and straighten our arm. Hair muscles are called “Arrector Pili”muscle and they are made of smooth muscle fibres. Our Pectoral muscle is in our chests and our Gluteal muscle belongs in our buttox, each muscle has muscle cells made of protein and fillments. Some problems the Muscular System can get is Atony, (stiff and sore muscles), Zenker’s Degeneration in the skeletal muscle and when your Pelvic Floor muscle tightens. You can care for your Muscular System by sustaining a good posture and healthy weight. In the future scientists will probably have better technology and better robotic muscles to use on humans.
The Circulatory System:
The Circulatory System’s job is for the heart, blood, veins, cappilaries and ateries to send oxygen and nutrients around the body. The heart pumps because of cardiac tissue and inside the heart is the aorta, left and right atrium, left and right ventricles and gate like valves. The right side of the heart takes blood to and from the heart and the left side collects oxygenated blood from the lungs. Blood is made from plasma, white blood cells, platelets and red blood cells. The stages of the colours of a bruise are: red, bluish purple, green or yellow, then finally light brown. The Respiratory System is related to the Circulatory System because they both use the lungs.
The Lymphatic System:
The Lymphatic System was discovered by Thomas Bartholin in 1652. The system is made up of the spleen, tonsils, thymus, lymph nodes, certchyli, thoracic duct and it’s job is to send lymph and white blood cells though blood vessels around the body. Doing meditation or yoga and eating healthy foods helps your Lymphatic System and your Immune System because both these systems are connected. A cancer you can get is called Lymphoma in the Lymphoid tissue, it makes you have fevers, weight loss, sweating a lot and it stops your body making white blood cells. Lymph nodes help your body fight fungus and disease, and if we didn’t have the Lymphatic system we would have severe swelling because of too much blood in the bodies vessels. In the future, scientists want to develop a 100% safe cure for chemo therapy.
The Urinary System:
The Urinary System is made up of the kidneys, Ureters, Sphincter and Urethra, it was discovered in 1540 by Andeas Vesaliaus. The system’s job is to filter our blood in the kidneys and turn body waste, sweat and water into urine, the nephrons in the kidneys help with this process. Two main problems the Urinary System can have are Kidney Cancer were you experience blood in your urine, unexplained weight loss and fevers, and Kidney Stone were salt gets into your kidney and forms salt crystals that block urine. In the future of the Urinary System scientists hope to have more and new improved technology and the use of more 3D printers for medical procedures.
The Skeletal System:
The Skeletal System is the system of all the 206 bones in our body (306 for babies) and it helps keep all our organs in place. It was discovered over many years, but the first person to study the system was Gaylen. Although our bones are tough, diseases such as Osteoporeous and breakages can still occur, the different types of fractures you can get are transverse, oblique, spiral and commiuted. Having lots of calcium and vitamin D is very good because it makes your bones stronger. In the future the use of bionic bones want to be more developed and useful and scientists want to start using a re-growth formula to grow back bones and skeletons.
The Respiratory System:
The Respiratory System helps us to breathe and it was discovered by Mr. Hoohe when he found out that the lungs act as a pump. The mouth, nose, lungs, trachea and diaframe are the main parts that make up the system. Astma caused by narrow airways, Bronketighthes, Emphysema, Hay fever, Infulsemia and pneumonia. are the main problems that affect the system. Emphysema and Lung Cancer are caused by smoking so if we don’t smoke we won’t get a chance to get either one of the diseases. In the future scientists want to be able to grow parts of the Respiratory System.
The Digestive System:
The Digestive System was discovered over many years but the person that discovered that there is acid that breaks down food in our stomach was William Beaumont in the 1820s. The stomach, Liver, Rectum (stores waste), appendix, gall bladder, pancreas, small and large intestines and oesophagus make up the system and their job is to turn food into energy and waste into poo, it also helps us eat and drink. Your stomach is a stretchy sac that makes food in to a liquid mixture and it does this by all the gastric juices in our stomach. Your liver is a filter that seperates harmful chemicals and nutrients, it also produces bile.
