Definition of the gyro device
The circulatory system, or circulatory system, is the organ through which the blood moves through the body, consisting of the heart, blood vessels, and blood. The oxygen-rich blood is transported from the lungs and heart to the entire body through the arteries. Located between the arteries and veins, and then returned oxygenated blood to the lungs and heart across the veins.
Components of the gyro device
The heart
A muscle member of the size of the fist, located behind the bone of the shear to the left, and pump blood through a network of blood vessels, and located on the surface of the heart, coronary arteries, providing oxygen-rich blood, and also a network of nerve tissue through it, Constriction of the heart or its spread, surrounded by a membrane called tumors, it is worth mentioning that the heart contains four chambers, namely:
- Right Atrium: Receives blood from the veins, and pumps it to the right ventricle.
- Right ventricle: receives blood from the right atrium and pumps it to the lungs, so that it is absorbed by oxygen.
- Left Atrium: The oxygenated blood - saturated with oxygen - is received from the lungs and pumped into the left ventricle.
- Left ventricle: Oxygen-rich blood is pumped to the rest of the body. Its contractions exert pressure on the blood pressure, making it the strongest of the heart chambers.
Blood vessels
Blood flows to the body through a large network of blood vessels with a length of more than 60,000 miles. There are three main types of blood vessels:
- Arteries: The transfer of oxygen and nutrients to the tissues of the body away from the heart, the most important is the aorta, a large artery that comes out of the heart, and the branches of the arteries become smaller as it moved away from the heart.
- The veins: return oxygen-free blood to the heart and grow closer to the heart. The most important is the upper vena cava, which transfers blood from the head and arms to the heart, and the lower hollow vein that carries blood from the abdomen and legs to the heart.
- Capillaries: Thin blood vessels that connect arteries and veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and waste to and from cells to pass through.
