The heart is a hollow muscular organ, approximately the size
of it's owner's fist. Actually positioned center of the chest area, between the
lungs and is actually divided into 4 chambers. The upper chambers are known as
the atria and the lower chambers are known as the ventricles. The right and
left sides of the heart are divided by a muscular wall popularly known as
septum, this prevents deoxygenated and oxygenated blood from mixing together.
If you are able to think of the pipe system in the home
providing water as well as heat to you every day, metaphorically speaking, the
home represents your heart and the pipes are the blood vessels that will found
throughout our body systems. Blood is pumped from the heart around all parts of
the body through a complex transport system consisting of arteries, veins and
capillaries (veins and arteries). The heart beats approximately 100,000 times
daily as a way to supply our cells with oxygen rich blood and pumps about
2,000
gallons of blood through it's chambers daily and this how you can imagine the anatomy and physiology of heart works.
Blood circulation follows a precise route and might be
summed up as follows;
1. The right atrium receives deoxygenated blood from the
superior and inferior vena cava.
2. The blood is then pushed across the tricuspid valve down
into the right ventricle. The tricuspid valve you'll find is a small flap that
stops the rear flow of blood between the chambers upon the right side.
3. When the right ventricle fills up, the blood is then
propelled directly into pulmonary artery which then travels to the lungs where
gaseous exchange occurs.
4. Whenever the lungs remove 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
that is then pushed down into your left ventricle throughout bicuspid valve.
The bicuspid valve prevents the back flow of blood toward the left side.

7. Blood becomes deoxygenated once more and returns onto the
superior and inferior vena cava exactly where the process begins again.
Like I stated previously, this just supplies you with a
quick overview of the anatomy and physiology of heart, it's function exactly how it transports blood
around the body. If you find yourself carrying out any anatomy and physiology
study, always check in summary all areas as above. Using visual tools an
example would be diagrams is a good technique to spice up your notes. Whether
or not can't draw like picasso, regardless of. To symbolize the heart you'll be
able to draw a square shape or a circle and divide it equally into 4 chambers.
It only procides you with an idea of the layout of the heart and contains been
shown that learning visually might be so much more effective than just reading
something over and over.
