The Human Heart

The human heart is slightly bigger than the size of ones fist. It is situated at a very safe place which is between the cage bones, i.e., in the center of the chest. Usually it is slightly on the left side of the chest but in rare cases, it can be found on the right side. Heart is responsible for the blood flow to every single part of the body by constant contraction and relaxation of cardiac muscles. This is the reason why we hear rhythmic beats all the time. Heart pumps the pure blood to the different...

Human Dive Response; Changes in Heart Rate While Resting and Submerged

The Changes of Heart Rate of Students during Human Dive Response when Resting and Submerged Abstract The dive response is known more popularly as a mammalian dive reflex. It is a survival mechanism built into mammal’s bodies, essentially. Over the years, scientists have been determined to find what triggers mammals to have a decreased heart rate when submerged under water allowing them to stay under the water longer when they do not typically live under water. In this experiment, we tested...

How exercise effects heart rate

Effect of Exercise on Heart Rate. Aim: The aim of this experiment is to find out how different intensities of exercise effect the heart rate I will measure it in beats per minute using a polar heart rate monitor. Hypothesis: I predict that as I increase the intensity of the exercise I do, that my heart rate will increase. This is because as I exercise more intensely I will need more blood to my muscles to supply oxygen and take away carbon dioxide; therefore my heart is going to have to beat...
