How Blood Is Formed In The Body: Everyone knows that there is blood in our body. But many people are not aware of where this blood is formed in our body or where it comes from. Blood formation in our body starts from the bone marrow present inside the bones. This bone marrow is a kind of soft, spongy substance, which is filled in the middle of the bones. This is the place where approximately 95 percent of the body’s blood cells are produced. After growing up, most of the bone marrow is found in our hip bones, chest bone and spine bones. Some other organs of the body also play an important role in keeping the blood cells balanced, these include lymph nodes, spleen and liver. These organs together decide how many blood cells will be formed at a given time, when they will break down and when they will convert into a particular type of cell.
All blood cells formed in the bone marrow are initially in the form of a stem cell. These stem cells gradually change and develop into different types of cells. These include red blood cells, white blood cells and platelets. When these are in incomplete form, they are called ‘blasts’. Some blasts remain in the bone marrow and develop further, while some go to different parts of the body and become fully developed cells.
What is the function of each blood cell?
red blood cells : Their main function is to deliver oxygen from the lungs to the entire body and to bring the carbon dioxide produced in the body back to the lungs. A protein called hemoglobin present in these cells makes this process easier.
white blood cells: Their job is to protect the body from infection. These include many types of cells, such as neutrophils, eosinophils, lymphocytes, monocytes and basophils. Each type of cell is specialized in fighting a particular type of infection.
Apart from this, platelets work to coagulate blood in the body, so that bleeding can be stopped in case of injury. If there is a deficiency of any of these three in the body, then its symptoms start appearing in the body.
What is blood?
Blood is the life-sustaining fluid that continuously flows in the blood vessels throughout the body. These vessels are of three types: Artery, Venous and Lyrics. Blood circulates throughout the body through these pathways and supplies oxygen, nutrients and essential elements and helps in removing waste materials.
