Online Anatomy - Anatomy and physiology study is generally broken down into 12 sections, with each section representing one system in the body, for example, the endocrine system. When you start revising, it can be recommended that you're taking 1 system of 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 your respective anatomy and physiology study and write out concise notes on that area. To provide you with an example and for your purpose of this article Let me give a brief overview of the heart and it is role in blood circulation. The heart is often a hollow muscular organ, approximately the sized it's owner's fist. It is positioned within the center with the chest area, between the lungs and it is divided into 4 chambers. The upper chambers are called the atria and also the lower chambers are called the ventricles. The right and left sides with the heart are divided with a muscular wall referred to as septum, this prevents deoxygenated and oxygenated blood from mixing together. If you can think of the pipe system within your house providing water and also heat for you on an everyday basis, metaphorically speaking, your house can be your heart along with the pipes will be the blood vessels which can be found throughout our bodies. Blood is pumped through the heart around all the parts with the body by having a complex transport system composed of arteries, veins and capillaries (blood vessels). The heart beats approximately 100,000 times each day to be able to produce our cells with oxygen rich blood and pumps about 2,000 gallons of blood through it's chambers on an everyday basis. Blood circulation follows a certain route and may be summed up as follows; 1. The right atrium receives deoxygenated blood from your superior and inferior vena cava. 2. The blood is then pushed over the tricuspid valve down in to the right ventricle. The tricuspid valve can be a small flap that prevents the rear flow of blood between your chambers for 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 take away the carbon dioxide, the deoxygenated blood becomes oxygenated and returns back for the heart via four pulmonary veins. 5. The blood enters the left atria via these pulmonary veins and is then pushed down in to the left ventricle over 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 the upper body with oxygen rich blood along with the descending aorta which supplies the lower body with oxygen rich blood. 7. Blood becomes deoxygenated once more and returns for the superior and inferior vena cava in which 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 around the body. When you're carrying out any anatomy and physiology study, always make sure to summarize all areas as above. Using visual tools for example diagrams is really a great approach to spice your notes. Even if you can't draw like picasso, it does not matter. To illustrate the heart you can draw a square shape or even a circle and divide it equally into 4 chambers. It simply gives you an idea with the layout with the heart and yes it has been proven that learning visually may be considerably more effective than just reading something over and also over again.
