Blood circulation in the human body

Arab speaking world Ibn al-Nafis (1210-1280) for the first time for the circulation of small and intended circulation of blood between the heart and lungs

And then about four centuries, the British came in 1678, "William Harvera" to talk in detail about the major session and meant by the circulation of blood between the heart and the rest of the body

The whirlwind tour of the blood in the human body, reaching every cell of it, it carries oxygen, food, any life, and carries them waste, produced by and dispose of them through their work. On top of this waste carbon dioxide, which in turn get rid of it through the process of blood purification and cleaning takes place in the lungs

And the blood passes through these tours in the blood vessels of different capacities, size and composition

Called vessels that carry blood from the heart to the body with the other members of the arteries, while the vessels called that carry blood from the organs of the body to the heart to the veins

Everyone shall be two sessions: session of the blood or circulatory system and the other for lymph

And is divided into the circulatory system or the blood circulatory system into three parts, all working at the same time

session or session pulmonary micro*

the plenary session or the session the major*

 portal session*

Valdorh Minor or pulmonary circulation carry blood to the lungs where Blue gets rid of carbon dioxide and provide themselves with oxygen. This is because the blood red color and loaded with Booxgen to the heart

The plenary session of the transfer of fresh red blood to the tissues

In the blood leaves the capillaries textile how it receives oxygen and carbon dioxide and waste, to lead them to and from the heart to the lungs through the session the minor replaces oxygen as carbon dioxide

The course portal (PORTAL-CIRCULATION) is the circulation to the liver, in which the blood received from the spleen, pancreas, stomach and intestines, and his liver converts glucose in the blood to glycogen is retained as a reserve, to come out in the case of need the body to him, as he turns Residue for cellular metabolism Albrootidi to acid urea, so that you Bafrazha kidneys with the urine

The heart occupies the main center in the circulatory system. It is the first reference and last, a pump that receives blood vessels and pay to a permanent movement does not end only with the end of life

Off blood from the heart, specifically in the left pane from any of the right ventricle, pulmonary artery through the pulmonary artery carrying blood saturated with carbon dioxide to the lungs Vivra to the two main left and right.

These two branches and the branches to turn up each and every one of them to a particular lobe of the lung

Such as branching and continues back to the tree even turned into a large network with homogeneous Onsak lung (lung cysts) Alveoles where it is the process of purification and gas exchange.

Gives blood how it surplus of carbon dioxide and takes what it needs from oxygen and returns through the veins that are formed in a manner opposite to the branch arteries, so take their final form and make up the four pulmonary veins carry blood saturated with oxygen to the heart, specifically the left atrium

This process is called the whole circulation of small or micro

What is different about the major micro-session

Is essentially different from the major arteries that carry blood the blue blood of any carrier to carbon dioxide, while veins carry the blood red of any dreamer purified of oxygen, while in session, the major arteries that carry blood red while veins carry blue blood

Off the major blood during the session of the left ventricle through the aorta to various parts of the body where this artery branch arteries of the multiple different names in different members that link to it and continue until you reach Baltafra small branches to each cell in the body

Up blood, then, to the members of the body are all loaded with oxygen and return, carrying carbon dioxide and other waste to accumulate through the veins that are formed in the same way that we have seen in the course smaller, and carry it to the heart through the Wreden key are called venae cavae veines caves, one of the inferior vena cava vena cava inferior , which collects blood from the lower limbs to take it to the right atrium of the heart, while blood accumulates from the upper by superior vena cava vena cava superior to hurt in turn, also in the right heart atrium

From there off to the right ventricle, which pumps it through the pulmonary artery to the lungs to the cycle begins again small

It should be noted that the blood is subject during its great to be in the process of purifying the kidneys, where blood is liberated from some of the material excreted in the urine through a complex process of absorption and excretion

The subject also to the purification of the other place in the liver than during the generic part of the session, major, and are made through the portal vein (portal vein), which is transmitted through which the blood coming from the intestines and abdominal organs other, which also holds the food gained from foods that are undergoing the liver where it is receive. Valqaibd as we know is a laboratory chemical in the body

The sessions Aldmoatin Mvsoltan completely from each other only in some diseases that remain a slot or more between the wall of the atrium or right ventricle Tsalhma Bashbahiama Aloasrin

Some of these diseases lead to congenital cyanosis, and sometimes keep the link between the pulmonary artery and the artery Alarbehr, called the ductus arteriosus, impassable, which also leads to mixing blue blood with blood red
