The thing that I've been curious about is how your blood travels through your body and how does your heart pump that blood throughout your body. . These questions have always come to mind: How does your heart pump blood to go into our blood vessels? How does the blood make it so that you can feel your pulse? I have wondered if the beat of your pulse has/or does coincide with the beat of your heart.
Also, along with the beats do they both coincide with making one beat at the same time or rythmic beating or do they not beat at the same time. The reason I was interested in this specific phenomenon was because when ever I exercise or workout for a long time I have to feel my pulse and time the beats and I have always wondered how we are able to feel our pulses or where they came from and since we could feel our hearts beating fast because we are breathing really hard if they were linked together and if their beats are similar or not.

I think there is a lot you can learn about how the heart works. I'm not quite sure how the heart pumps blood and what the heart needs to do that, but a project that can be possible is reenacting the heart. Maybe the heart as a plastic bag or something. Then we can have hand pumps or tubes representing the veins and arteries. I don't really know how the heart works so I can't think of something really specific, but if we had those materials, I think it is possible to reenact a heart and learn about what it does.
ReplyDeleteIn third grade I learned about the body, and heart and such, so from what I recall, I know that the blood flows from the heart, around the body, becoming "dirty" and it comes back to the heart, where it is cleaned and sent out once again. Its a whole repeating cycle.
ReplyDeleteWhen you exercise, you are able to feel your pulse at places such as the neck because of big arteries you have around your body, such as the jugular. The heart beats and so the arteries beat as well, because they are pumping blood. There is no double beat, unless you have a heart condition, but thats a whole different story.
One thing you could do, is research how blood travels, and get tubing and a small pump. and make a "body" to see how every thing works, with arteries and your heart, and what happens when your heart rate increases/decreases.
