What are blood vessels?
Have you ever seen a cargo ship on television loaded with content? But how about when it’s empty! What would it be classified as then?
Would you believe a vessel?
What then is a vessel?
It’s an empty container that’s used to transport an item or object. Now we have the principal of a blood vessel. Blood is the item to be transported through the three types of blood vessels; the veins, the arteries, and the capillaries are responsible for that. In the case of the human body, human blood vessels function as hollow tubes to circulate the blood.
Here are a couple of interesting facts about the function of the blood vessels!
If we stripped out the blood vessels (veins arteries and capillaries) from a child to a full grown adult and laid them out length wise, you could travel around the globe at least twice as a child and four plus times as an adult.
Do you know what the circumference of the earth is?
The circumference of the earth is about 24,901 miles at the equator or 40,075 kilometers. In other words, if you could drive your car around the equator of the Earth (yes, even over the oceans), you’d put on an extra 40,075 km on the odometer. It would take you almost 17 days driving at 100 km/hour, 24 hours a day to complete that journey.
So that means that the blood vessels in a child will stretch out over 50,000 miles and as an adult over 100,000 miles.
Your blood vessels have many important tasks but two important functions are the measurement of blood pressure and your pulse.
In skin care, it’s important to have consistent blood flow throughout your skin to maintain its healthy look. Since the skin is comprised of three layers, the epidermis or the outer layer, the dermis or the inner layer, and the subcutaneous fat or the inner layer, any change in the flow of blood through the blood vessels to your skin will cause the appearance of your skin to deteriorate.
Rich steady blood flow is important because oxygen and nutrients are transported through the blood vessels to other organs of the body.
So what’s the largest organ on the human body?
The answer is your skin and it accounts for 75% of your body.
How can you tell if you’ve got a problem with your blood flow? The obvious answers are to visit the doctor and get a blood test. But, here’s a way to perform a visual check of the blood.
Take a quick look at one of your veins. The best place to look would be at the underside of your wrist. If not there, try the ankle or even your hands. What you’re looking for is the deep maroon color of the blood that is visible through the skin. Now because the walls of the blood vessels (the veins) are going to be much thinner than the arteries, you may see a bluish tinge to the color.
If anything appears abnormal, it’s best to get it checked out. If you’re a youngster, you can try this trick on mom or dad. If not them, try grandma or grandpa because as the older we get the more translucent our skin becomes and the easier it is to see our blood vessels.
In summary, we’ve discovered that blood vessels are hollow tubes that transport the blood which is rich with oxygen and nutrients all over the human body. And, the major blood vessels come in three types: arteries, veins, and capillaries.
