Blood circulation: this is how it works in detail
It is a vast network of organs and vessels responsible for blood flow, nutrients, hormones, oxygen, and other gases to and from cells.
Without a circulatory system, the body would not be able to fight disease or maintain a stable internal environment - such as the appropriate temperature and pH - known
The heart, blood and blood vessels make up the blood circulation as a whole.
It includes pulmonary circulation, a "loop" through the lungs where the blood oxygen is filtered, and it also includes regular blood circulation, which passes through the rest of The pulmonary circulatory system sends blood through the pulmonary artery to the lungs and returns oxygenated blood to the heart through the pulmonary veins.
Did you know: An adult human body contains about 4.5-5.5 liters of blood, while an infant who weighs between 2.3 - 3.6 kg increases the blood volume in his body.
How does blood circulation in the body? What is the role of each circulatory system in pumping blood daily to and from all parts of the body?
Blood circulation: this is how it
works in detail
Blood travels to all parts of the body and its cells are laden with food and oxygen at times, or back from them loaded with toxins and excreta that must be disposed of again.
So what is blood circulation? Learn about its various parts and how it works in this article.
How does blood circulation work in the human body?
When the heart beats, it pumps blood through the blood vessels circulating throughout the body, which together with the heart form what is called a blood circulation, or circulatory system.
The blood vessels are flexible tubes through which blood runs to reach its destination back and forth.
And the work of blood is not limited to carrying oxygen from the lungs and food from its sources to the body, but also carries with it on the journey back the waste and toxins that must be disposed of, such as carbon dioxide.
What happens here is very important to maintain the vitality and continuity of work of all parts of the body, so that the body remains healthy, strong and healthy
What are the types of blood vessels?
Man puzzled
The blood circulation in the body contains three types of blood vessels, namely:
1- Arteries
The most important of them is the aorta that appears to leave the heart in any anatomical drawing that you will see for the heart.
Arteries generally carry oxygen-bearing blood away from the heart to reach all tissues in the body, and the arteries branch out on their way repeatedly, getting smaller and smaller as they move away from the heart.
2- Capillaries

Blood circulation: this is how it
works in detail
It is the small and delicate blood vessels that connect arteries to blood vessels.
The walls of these thin vessels allow the exchange and passage of food, oxygen, carbon dioxide and other waste through it to and from the cells of different organs.
3- Veins
These vessels return blood to the heart again in the blood circulation of the body, and this blood is characterized by lack of oxygen and is rich in waste that must be purified blood to leave the body.
The size of the veins increases as we
get closer to the heart more and more, and there are two important types of
veins:
The superior vena cava transports blood that is loaded with waste from the head and arms to the heart.
Its inferior vena cava transfusions carry littered blood from the feet, abdomen and abdomen to the heart.
The length of the vessels in the body’s circulation is about 60,000 miles, and if you like roughly, this is equivalent to the length of a strip that you can wrap twice or more around the globe.
The blood circulation in the human body does not stop with the support of the heart (read: How do we keep the heart healthy?), Which constantly pumps blood into the blood vessels.
Where is the heart located and how does it look?
· The heart is located in the chest area, protected by the rib cage, and is located to the left of the chest between the lungs.
· The strong muscular walls of the heart, which pumps blood, contract the so-called blood circulation of the human body.

Blood circulation: this is how it works in detail
The main vessels connected to the
heart are:
- Aorta.
- The superior and inferior vane cava
- The pulmonary artery, responsible for carrying the blood returning to the heart, is poorly
- oxygenated to the lungs, where it is re-saturated with oxygen.
- The pulmonary veins, which return oxygen-saturated blood from the lungs to the heart.
- The coronary arteries, which supply the heart muscle with the blood it needs to make it continue to function and constrict.
