Blood transfusion
When our heart beats, it pumps blood to blood vessels, and this action is called communication system. These blood vessels are elastic, muscular tubes, which carry blood thrown by the heart into the whole body.
Blood is an extremely important fluid in our body, which carries oxygen and other nutrients in the whole body tissues including lungs, along with its flow. Apart from this, it also removes harmful substances such as carbon dioxide from the body’s tissues. It is very important for the health of our lives and whole body parts.
Three main types of blood vessels:
Arteries – This arteries begin with the largest heart and arterial artery, Aorta. It transmits nutritious blood from the heart to all tissues of the body. These are divided into many branches which goes as far as the heart goes from the heart to the body.
Capillaries – These are small and thin blood vessels that combine arteries and veins. The thin walls of these vessels have movement of nutrients, oxygen and carbon dioxide in different parts of the body.
Veins – These are blood vessels that carry blood back into the heart. This blood is free of oxygen and nutrients, and it is taken out of the body. These nerves are as thick as they are close to the heart. In these veins, the superior Vena Cava is all big nerve, it brings blood to the heart with the brain and arms. At the same time, Inferior Vena Cava is the smallest vein that brings blood and legs from the blood to the heart.
The massive system of these blood vessels arteries, veins, and cells is 60,000 miles long. It is so much that they can be wrapped twice on the whole world.
Where else does the heart look?
Under the cage of the heart, rib cage, it is between the left side of the chest (sternum), and between the lungs. By looking at the heart outwardly, it is known that it is made up of muscles. The walls of its strong muscles transmit blood to the body through shrinkage and pumping. Coronary artery is on the surfaces of the heart, and their function is to carry oxygen-rich blood to the heart muscle itself. The main blood vessels in the body are Superior Vena Keva, Inferior Vena Keva and Pulmonary Vines, which enter the heart. Apart from this, the pulmonary artery and the aorta that comes out of the heart, carry oxygenated blood throughout the body.
The heart is a hollow organ divided into four chambers. It is divided into the right and left muscular walls which are called septum. In addition, its two right and two left parts are also divided into two and two parts, the upper part is called the arteri and the lower parts are called ventricles. These arteries take blood from the veins, and these two bottom ventricular ventricles leave the blood in the arteries.
Atria and ventricles work together in the process of contraction and opening of the heart. Their work is to take blood and leave it in the heart. As soon as the blood emerges from every chamber of the heart it turns out through a valve.
There are four types of valves inside the heart:-
- Mitral valve
- Tricuspid valve
- Aortic valve
- Pulmonic valve
Trichspid and mitral valves are between the atria and ventricles. At the same time, the aortic and pulmonic valves are between the ventricles and the main blood vessels emitting from the heart. Heart valves also work exactly like pipelines that work in your homes. It prevents blood from moving in the wrong direction. Every single valve has a set of flaps, called liphlets or capsules.At the same time, there are three liphit in the mitral valve, the rest in the rest is three. These lipids are attached to the fibers of fibrous tissue, which are called annulus. This helps the heart stay in their proper shape.
The liplets of the mitral and trichspeed valves are associated with hard fibers which are called chordae tendineae. These thieves are similar to the supporters found in the parachute. These valves are spread from lipids to small muscles. These papillary muscles are called. These musculosms are part of the inner walls of the ventricle.
Blood passing through the heart
The left and right part of the heart work together for blood flow. The flow of blood in the heart, lungs, and whole body is explained in detail below.
The right side of the heart
The blood enters the heart through two major nerves (Inferior and Superior Vena Keva). It emits oxygen-free blood taken from the body into the right atrium. As soon as the atrium shrinks, the blood goes out of the atrium on the right by the open tricuspical valve and goes into the ventricle on the right side.When this ventricle is full, then the tripex valve closes. When this ventricle contracts, the blood does not return. As soon as the ventricle shrinks, the blood gets out of the palmoic valve, and it reaches Pulmonic arteries and lungs. After reaching the lungs and arteries, it reaches the left arterium by carrying blood, oxygen and pulmonary veins.
The left side of the heart
Pulmonary veins transmit this oxygenated blood from the lungs to the left atrium of the heart. As soon as the atrium shrinks, the blood is released from the left atrium and reaches the left ventricle through the mitral valve. When this ventricle is filled with blood, then the mitral valve closes. The blood could not penetrate the back atrium. After this, when the ventricle contracts, the blood goes through the aortic valve and reaches the aorta and then into the entire body.
Blood flow in the lungs
When blood enters the palmicic valve, it reaches directly into the lungs. This verb is called pulmonary circulation. The blood from the palmicic valve reaches the lungs through the thin capillaries while in the pulmonary artery. Here oxygen goes through the Capillery walls, the small air into the lungs and then into the blood.At the same time, the waste product of metabolism carbon dioxide reaches the blood into the asteroids. After this, when we release breath, carbon dioxide also gets out of it. As soon as the blood gets purified and oxygen is found in it, it reaches the left atrium through the pulmonary veins.
