When you begin revising, it's recommended that you're taking 1 system from the body and learn it on its own. Various body systems are similar naturally so learning them together might cause confusion. Take each area of your anatomy and physiology study and write out concise notes on that area. To give you an example and for that purpose of this article I'll give that you simply brief overview of the heart and role in blood circulation. The heart can be a hollow muscular organ, approximately the size of it's owner's fist. It is positioned inside center in the chest area, between your lungs and is split into 4 chambers. The upper chambers are called the atria and the lower chambers are called the ventricles. The right and left sides in the heart are divided with a muscular wall known as the septum, this prevents deoxygenated and oxygenated blood from mixing together. If it is possible to think of the pipe system within your house providing water as well as heat to you on an everyday basis, metaphorically speaking, your home is your heart and the pipes will be the blood vessels that are found throughout our bodies. Blood is pumped from your heart around all parts from 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 as a way to supply our cells with oxygen rich blood and pumps about 2,000 gallons of blood through it's chambers on a regular basis. Blood circulation follows a certain route and might 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 through the tricuspid valve down into the right ventricle. The tricuspid valve is really a small flap that prevents the rear flow of blood involving the chambers on the right side. 3. Once the proper ventricle fills up, the blood is then propelled to the pulmonary artery which then travels to 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 also then pushed down into the left ventricle over the bicuspid valve. The bicuspid valve prevents the back flow of blood for the left side. 6. As soon as the left ventricle fills up it contracts, forcing the blood to the aorta which then branches to become the ascending aorta which supplies the upper body with oxygen rich blood as well as the descending aorta which supplies the low body with oxygen rich blood. 7. Blood becomes deoxygenated yet again and returns to the superior and inferior vena cava where the process begins again. As I mentioned above, this just gives which you brief overview in the heart, it's function and the actual way it transports blood round the body. When you eventually be carrying out any anatomy and physiology study, always ensure that you summarize all areas as above. Using visual tools for example diagrams can be a great way to spice your notes. Although you may can't draw like picasso, it won't matter. To illustrate the center you are able to draw a square shape or a circle and divide it equally into 4 chambers. It just offers you an idea of the layout in the heart and it continues to be proven that learning visually could be a lot more effective than just reading something over as well as over again.</div>
