"What happens when you exercise (2)" Our Body PPT Courseware 3
1. Understanding people with heart
1. Heart position:
Located in the middle left lower part of the chest.
2. Form size:
Shaped like a peach and as big as a human fist.
3. What is the heart doing when it keeps beating?
The oxygen needed by the human body is inhaled by the lungs and enters the blood, and then transported by the heart to various parts of the body through blood vessels. At the same time, waste products such as carbon dioxide are collected and excreted from the body.
4. A normal person's heartbeat should be between 60 and 100 beats per minute. Anything above or below is considered abnormal. But the number of heartbeats varies at different ages. The heartbeat of people over 60 years old can slow down, but the slowest cannot be less than 50 beats per minute. For athletes or strong physical workers, because the cardiac output is significantly larger than that of normal people, the heartbeat rate can be around 45 beats.
1. Approximately how many times does our heart beat in a day?
60 times × 60 minutes × 24 hours 86,400 times
90 times × 60 minutes × 24 hours 129,600 times
2. The heart has a short rest between two beats.
If the interval between two heartbeats is one second, that is one beat per minute. Then, the heart actually completes beating in 0.2 seconds, and the remaining 0.8 seconds is resting.
3. Since the heart will take a short rest, does it need more rest? How to give your heart more rest?
Get reasonable rest and good sleep
