Most amazing facts about the blood circulation in your body

The enormously big human blood circulatory system puzzled scientists over centuries to understand fully.

Blood, the most abundant liquid tissue is present everywhere in the human body. Blood comprises red blood cells, white blood cells, and platelets. The circulation of blood in the human body needs the heart to pump throughout, eventually helping all the cells, tissues, and organs to get sufficient oxygen and nutrients. Following are some exciting insights about blood circulation in the human body. Read on.

The vastness of the blood circulation system:

The entire path covered by the circulation system is around 66,000 miles, enough to wrap the earth twice. You just cannot imagine how big your circulatory system is. This large length is intricately stacked inside the body.

Pumping of heart and volume of blood:

Generally, the human heart beats 2-2.5 billion times for a person with 75 years of lifespan. For every heartbeat, 1.7-2 ounces of blood get pumped out by your heart. So, a person with 75 years of lifespan pumps approximately 250 million quarts of blood. Yes, you read it correctly. It is that much in quantity.

Fascinating facts about red blood cells and hemoglobin:

One RBC contains approximately 270,000,000 hemoglobin molecules, while 4 oxygen molecules are carried by each hemoglobin molecule. Basically, hemoglobin scoops up oxygen from the lungs to release the other parts of the body. Around 3 million RBCs get replaced every second. The quantity and size of RBC are so high that it can stretch upto 31,000 miles. Thus, RBCs remain in the squeezed way to move through blood vessels.

The link between body size and heart rate:

The heart rate is always inversely proportional to the body size. So, a smaller animal will have a faster heart rate than a bigger animal. The heart rate of an adult human is 75 beats/minute, which is equivalent to the heart rate of adult sheep. can you guess the heart rate of the largest living mammal, the blue whale? A blue whale’s heart beats only 5 times in 60 seconds. On the other hand, the heart rate of a shrew is 1000 beats/minute.

Study on blood circulation started centuries ago:

The Egyptian medical document named Ebers Papyrus reported about the circulatory system in the 16th century B.C. Historians confirmed that the description of the physiological connection between the living heart and functional arteries is provided there. Ancient Egyptians believed that the heart is the center of every function like memory, wisdom, emotions, and so on. Thus, people used to store the heart before mummification.

If someone goes through a tough emotional state like the loss of relatives or breakup, a medical condition arises called broken heart syndrome. Due to sudden and temporary weakening of the heart muscle and hampered blood circulation, he/she can have symptoms of heart attacks. So take care of your heart and circulation system.
