For scientists have puzzled function of blood in the human body.The secret of this, they are still unraveling, as the slightest deviation or violation of these features lead to the death of a person as soon as possible.
function of blood in the body is very diverse.The main function of blood are to transport substances and transport of oxygen.Circulating through the blood vessels, it carries a considerable amount of nutrients for the body, such as oxygen, which is so necessary for the "breathing" of every cell of all living things.Also, the blood carries nutrients throughout the body, which dissolve in the body as a result of the food.From these and many other functions of the blood in the body depends on the health of each and every day of his state of health.But how often do we think about what we eat, what we drink and in general, what we breathe?Perhaps not everyone will give a positive answer to this question.
Many of our diseases are due to the fact that we do not always serious about our way of life.Therefore, let us consciously come to this issue and to reflect on what the function of blood and how they affect the body.
Slightly more than half (about 55%) falls on the share of water in the blood.This clear liquid called plasma, and has a pale yellow color.The remaining 45% is the share occupied by blood.Red blood cells called red blood cells, white blood cells - white blood cells it.There are still in the blood and platelets, which are called platelets.The color of our blood depends on the presence of hemoglobin.Called hemoglobin pigment oxygenated and having a scarlet color.Proceeding from the lungs to the heart through the arteries, the most oxygenated hemoglobin and spread throughout the tissues of the body, it has a rich red color.The blood is then returned back to the heart from the tissues of the body through the veins, and here it has a dark color, becausein hemoglobin is almost no oxygen.Then again, the blood enters the lungs, thus acquiring a scarlet color, asit is saturated with the regular portion of the oxygen, and the process is repeated.
And what is a plasma?
Plasma - is an aqueous solution, in which there are both positively and negatively charged particles - a sodium, potassium, chlorine, magnesium, and qualitative and quantitative composition of these ions like composition of sea water.Also present in plasma nutrients results metabolism, proteins, vitamins, hormones.They make up about 10%, and the rest - it is water.
Depending on the needs of the body and the number of blood cells in the formation of the blood is constantly monitored and regulated.What are the functions of the blood, and thus its basic components - erythrocytes, leukocytes and platelets?Erythrocytes
prevail among the components, which circulate in the blood.Hemoglobin is very dense in the red blood cells.The functions consist of erythrocytes to the blood vessels carry oxygen and carbon dioxide.Red blood cells are our vital components in the process of respiration and therefore oxygen uptake by us from the environment.
What are white blood cells?They are a kind of "defenders" of the body from different infections that penetrate into the bloodstream.Periodically collapsing, the cells in the body to form unwanted residues that white blood cells are also processed.Leukocytes are classified into monocytes, lymphocytes and granulocytes.
function of blood in the body is extremely important.This is primarily to ensure each cell all the important substances and the release of waste products and excretion out.All these deals are only five liters of fluid, which provide our livelihoods.
