One drop of blood can contain up to five million blood cells.

FOLLOWING on from last week’s article we know that the cardiovascular system is centred around the heart and it goes without saying that a healthy heart is critical to overall wellbeing.

Imagine all those blood vessels running through your body. All those veins and arteries with blood flowing through them. 

The arteries carry blood away from the heart and the veins carry it back to the heart. If you were to lay out all of the capillaries and veins end to end they would stretch for kilometres and kilometres.

I personally think that the cardiovascular system is there to be used. If you can find a balance between three types of exercise – those being light easy exercise, hard cardio workouts and some form of strength training then you will become really fit. 

You don’t have to do a hard cardio workout or raise your heart rate every time you exercise, simply find a mix between the three types of workout. 

Here are some interesting facts about the cardiovascular system:

• One drop of blood can hold up to five million red blood cells, and when you exercise you send these red blood cells around the body quicker.

•  It might be hard to imagine, but some capillaries are so small that blood cells have to move through them in single file.

• When your body is at rest it takes about six seconds for the blood to go from the heart to the lungs and back.

• The ‘thumping’ from your heart is caused by the four main valves opening and closing as they work.

I could go on and on but the main thing is that you exercise or start exercising and increase the use of your cardiovascular system. When you do, life will become much easier. 

Running up and down the stairs or having to dash across the road to avoid the oncoming traffic will seem much easier. Your heart will beat much more slowly when you’re at rest and ultimately will work much more efficiently. 

Some really fit guys I know have an amazing resting heart rate of 48 beats a minute instead of 70-72. This is because at rest their heart is working very efficiently and still doing the same job. It’s a bit like having a finely tuned engine in your car!
