The Heart


We all have a heart, but do we all know how it works?

A heart is in 4 main sections and it has a right and left atrium, it also has a right and left ventricle.

Blood Vessel: Transports blood.
Vein: Brings blood to the heart.
Artery: Takes the blood away from the heart.
Right Atrium: Is the smaller atrium and it does the least work compared to the left atrium. The right atriums job is to recieve blood from the body using veins.
Left Atrium: Does more work as it takes the oxygenated blood from the lungs using the vein.
Right Ventricle:Takes the blood that is in need of oxygen to the source of oxygen, the lung.
Left Ventricle: Transports the blood to the whole body using the artery.

Cardio-Vascular System: One of the systems which includs organs such as the vein and the artery's.
Aorta: Is an artery that takes blood to the whole body.
Valve: Is the reason which causes the blood to go one way.


THE WHOLE STORY: From a cell the blood goes to the heart using the blood vessel and also the pumping of the heart so the blood vessel can take the blood up. The blood vessel takes the blood into the right atrium which then goes into the right ventricle. After that the blood goes to the lungs using the artery, because the blood needs to be oxygenated. From there it enters the left atrium via the blood vessel, and then it goes to the left ventricle. The artery takes, the now oxygenated blood to the rest of the body.

Cool Facts:
Did you know that human heart beat 35 million times a year.

-Your system of blood vessels - arteries, veins and capillaries - is over 60.000 ( 96.000 km ) miles long. That's long enough to go around the world more than twice!

-The adult heart pumps about 5 quarts of blood each minute - approximately 2.000 ( 9120 liters ) gallons of blood each day - throughout the body.

-The heart beats about 100.000 times each day.

-In a 70-year lifetime, the average human heart beats more than 2.5 billion times.

-Blood is about 78 percent water

The way Google makes money

How Does Google MAKE MONEY??

The way Google makes money is by advertisement! When you search something on Google, there’s a section called “Sponsored Links”, and every time you click that link Google charges an amount of money for that click. But Google take it a step further, and this step makes a lot of money for the company. When you want to advertise with Google, the largest search engine, you have to choose keywords that you’re targeting. The price the companies pay for each keyword relies on how many other companies are paying Google for that keyword, so from here on Google uses a sort of bidding system. The price the company pays will rely on how many companies are bidding for that keyword. The higher the amount of companies bidding for the same keyword, the more money your company will pay. The price can differ from $1 to more than $100. Not bad for a click hey?? So really Google is getting paid by selling traffic to other websites.

Google makes around 40 million dollars annually but it can make up to 56.7 billion dollars annually.

Most of the money comes from advertising but there are other domains where they gain money.
