Biology: The Human Heart

What Is the Human Heart?
The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes. Every day, your heart can create enough energy to drive a truck 20 miles.

I choose the human heart as my key learning point because I believe that it is important that other people know how fragile a heart can be. Also, that the human heart is one of the most important organ in the human body. It is the most important organ because if the heart is not able to supply blood to all your other organs and tissues, they will die and when that happens you yourself will die too.

Real Life Situation:
The real life situation for the human heart is that every day, your heart beats about 100,000 times, sending 2,000 gallons of blood surging through your body. Although it’s no bigger than your fist, your heart has the mighty job of keeping blood flowing through the 60,000 miles of blood vessels that feed your organs and tissues. Any damage to the heart or its valves can reduce that pumping power, forcing the heart to work harder just to keep up with the body’s demand for blood. This real life situation is important because I believe it is very important for people to understand the major stuff the heart does to keep us alive and healthy.

The two websites that I used are and This is because both use the appropriate amount of diagrams and pictures so that others, like me, can have a deeper understanding. These websites are so special to my key point because they give a clear understanding to the topic and are pretty basic about how the heart is the most important organ of your body.

The journal I used is called the Development of the Human Heart. This is because it gives great understanding to my key point and it has definitions for all words that make tiny bit of sense. This journal also has a lot of writing in it so that people who are very interested in this topic can get all the information they need.
