Hello readers/heart-beaters! Today I'm going to be answering two important questions about the heart.
The first is: What are the effects of exercise on the heart?
Doing regular exercise is one of the top ways to keep our hearts healthy (as I have talked about in pervious posts). From the cardio regulatory centre in the brain, the heart beats faster and harder during exercise, and breathing becomes deeper and more frequent.
The second question is: What is your heart's main jobs in your body?
Your heart's job is to always be pumping blood through and around your body. Even when you're sleeping, your heart is still pumping blood and beating. If your heart were to stop because of diseases, heart attacks or strokes, you would pass away very quickly because your heart is one of the main organs in your body keeping you alive. The heart is also in charge of is providing the whole body with nutrients and oxygen.
Your heart pushes blood through 80,000km of capillaries!
