Online Anatomy - Anatomy and physiology study is commonly broken down into 12 sections, with each section representing one system with the body, for example, the endocrine system. When you begin revising, it is recommended that you are taking 1 system from the body and learn it on its own. Various body systems are similar in nature so learning them together might cause confusion. Take each area of the anatomy and physiology study and write out concise notes on that area. To present you with an example and to the purpose of this article I am going to give a brief overview of the heart and it is role in blood circulation. The heart is really a hollow muscular organ, approximately the size of it's owner's fist. It is positioned inside the center in the chest area, between your lungs and it is split up into 4 chambers. The upper chambers are known as the atria along with the lower chambers are called the ventricles. The right and left sides in the heart are divided with a muscular wall called the septum, this prevents deoxygenated and oxygenated blood from mixing together. If it is possible to think about the pipe system with your house providing water and heat to you personally on an everyday basis, metaphorically speaking, the house is your heart and also the pipes are the blood vessels which can be found throughout our bodies. Blood is pumped in the heart around every part in the body by having a complex transport system consisting of arteries, veins and capillaries (blood vessels). The heart beats approximately 100,000 times every day as a way to provide our cells with oxygen rich blood and pumps about 2,000 gallons of blood through it's chambers on a daily basis. Blood circulation follows a particular route and can be summed up as follows; 1. The right atrium receives deoxygenated blood through the superior and inferior vena cava. 2. The blood is then pushed from the tricuspid valve down in to the right ventricle. The tricuspid valve is a small flap that prevents the back flow of blood involving the chambers around the right side. 3. Once the proper ventricle fills up, the blood is then propelled into the pulmonary artery which then travels for the lungs where gaseous exchange occurs. 4. When the lungs eliminate the carbon dioxide, the deoxygenated blood becomes oxygenated and returns back to the heart via four pulmonary veins. 5. The blood enters the left atria via these pulmonary veins and is also then pushed down into the left ventricle with the bicuspid valve. The bicuspid valve prevents the rear flow of blood on the left side. 6. As soon as the left ventricle fills up it contracts, forcing the blood in to the aorta which then branches to get the ascending aorta which supplies top of the body with oxygen rich blood and the descending aorta which supplies the low body with oxygen rich blood. 7. Blood becomes deoxygenated yet again and returns for the superior and inferior vena cava where the process begins again. As I mentioned above, this just gives that you simply brief overview with the heart, it's function and the actual way it transports blood across the body. When you're carrying out any anatomy and physiology study, always be sure to summarize all areas as above. Using visual tools including diagrams is really a great way to spice your notes. In case you can't draw like picasso, this doesn't happen matter. To illustrate the center you can draw a square shape or a circle and divide it equally into 4 chambers. It gives you a perception from the layout of the heart plus it has been proven that learning visually can be much more effective than simply reading something over and over again.
