Your Amazing Circulatory System
One of the most active body systems among the rest is the circulatory system. It is a critical body system responsible for your wellbeing since its vital component is blood or ‘life.'
What is the Circulatory System?
The circulatory system definition sums up into a few words. It is a system that circulates blood when transporting nutrients, oxygen, and other vital body essentials while removing wastes.
The activity of the circulatory system begins when the small intestine passes food nutrients into the blood. Also, for the oxygen, it starts when you breathe, and oxygen enters through your nostrils or mouth to the lungs. The blood from the heart enters the lungs for oxygenation to which the system distributes to all the body's cells and tissues.
Amazing Facts of Circulatory System
The most intricate system among all the body systems is the circulatory system. It involves numerous complex activities that make up the system. Surprisingly, the length of all the arteries, veins, capillaries in an average adult equals to going around the planet earth two and a half times.
If you can join every blood vessel one to another end-to-end and stretch it out, it can cover a distance of approximately 100,000 kilometers (60,000 miles).
As if that is not enough, the blood circuit from the heart, lungs, and back to the heart can take only six seconds.
Circulatory System Organs
The circulatory system has four key features that play a significant role in ensuring your body is well-nourished and healthy. It is useful for the distribution of nutrients and other vital products your body needs for growth and maintenance.
The heart is an essential part of the circulatory system without which you cannot live. It sits at the center of the chest between the two lungs, tilting slightly to the left side.
The heart is the organ at the center of circulatory system activities. Every activity of the circulatory system begins and ends with the heart. Also, the entire body's organs and tissues depend on the heart organ for pumping out nutrients and oxygen-rich blood. The organ has two divisions that work differently from one another.
The Heart's Right Side. The heart right side deals with deoxygenated blood containing carbon dioxide that comes from the body cells as waste.
The oxygen-depleted blood enters the atrium (the right upper part of the heart) through anterior and posterior vena cava veins. The atrium then pumps the blood into its lower side, the right ventricle through the tricuspid valve. Once the ventricle is full of blood, the valve closes to prevent blood back-flow into the atrium.
The right ventricle releases the blood through the pulmonic valve and into the pulmonary artery for delivery into the lungs for oxygenation.READ MORE
