How Does the Heart Work?

Blood enters the heart into the right atrium. Next the blood flows into the tricuspid valve, then into the right ventricle. The valves in the heart keep the blood flowing in the right direction. Next the blood goes up higher in the heart into the pulmonary valve. Then when the blood leaves the heart and goes to the lungs. Once it reaches the lungs (which are so close to the heart) the blood fills up with oxygen. Then it comes through the pulmonary vein, into the left atrium. Next it comes down into the mitral valve and last it comes to the left ventricle.

Of the many muscles in the human body, the heart is the most important because of its hard job: Your heart pumps blood around your body. Your blood provides your whole body with the health and nutrients that your body needs to be strong and healthy. You may not have known that your heart actually takes tiny rests between each beat; that's why your heart sounds something like boom, boom rest, boom, boom rest. Your heart has two pumps: one on the left and one on the right. Here's what the job of the right side is: once the right side of your heart gets non-oxygenated blood coming from the body, it sends the blood to the lungs. The left side does something very different from the right: the left side gets blood coming from the lungs, and then pumps this oxygenated blood out into our bodies. Then this cycle repeats!

Did you know that a man's heart is heavier than a woman's?

A woman's heart beats faster than a man's

The  blue whale has the largest heart of all animals! Their hearts can weigh over 1,500lbs (680kg)!

Hey Anastasia, 

Interesting topic choice. The heart is certainly one of the most interesting and complicated organs and an integral aspect to learn about in order to understand human anatomy. I liked your post layout and thought that you did a great job of explaining how the heart functions! Also the little "fun fact" section at the end was a great addition. I do have one piece of constructive criticism though, try to expand your question from a generic how question to either a why question or a more specific how question. 

Keep up the good work!

Hi Anastasia!!

I always wanted to become a biologist! I bet that all doctors must deal with the human anatomy at some point of their studies. The heart and the brain are the most controversial organs discussed. The heart in some ways can be termed as the source of life in a human being. It performs a very critical function of supplying blood and other nutrients to the other organs of the body. It's therefore quite significant to find out how the mammalian heart functions. I love your conclusion and I am honestly obliged to find out more though facts do not need confirmation. More functions and more fun facts available in this site below..Good work.

Hey Anastasia,

I find your topic very interesting that you have told us about how the heart functions.

Your heart is a specialised muscle that pumps blood around your body. Blood carries oxygen and nourishment to all parts of your body and carries waste products to several organs, notably your lungs and kidneys, for removal.

Your heart is divided into two pumps, which work together. Blood coming back from the organs and tissues of your body enters the right side of your heart, which then pumps it to your lungs. Your lungs remove waste carbon dioxide from the blood and recharge it with oxygen.

The oxygen-rich blood returning from your lungs enters the left side of your heart, which then pumps it to all parts of your body, including your heart muscle itself.

This process ensures that there is always enough oxygen and nourishment for your body to work efficiently. Click here for a more detailed explanation of how your heart works.

I think that will help you do more research and this is a link to help you do priere research:http://www.heartfailurematters.org/en_GB/Understanding-heart-failure/How-does-the-normal-heart-work

Good luck in your research............

Hey Anastasia

I like your post on the ways the heart works.You have clearly explained on the circulatory system and maybe next time you may  tell us more about the diseases that are caused in the circulatory system maybe  lets say a diseases like;Coronary thrombosis,varicose veins and high blood pressure.

Hi Anastasia... This is a very educative research and we have learnt more about the heart and how it works . In Kenya we learn biology and how the heart works ,so we have learnt much...Good luck on your next research.

Hi Claire!

Thanks for commenting! And that it super neat how you get to learn about that in school!

rHello there!

I found your post so captivating and all I can remember about the heart and how it functions is the right and left auricle and the ventricles too.I would recommend you to state the illnesses that affect how the heart functions and the possible treatment activities.Below is a link that may be of use in coming up with your next post
