Production of red blood cells is controlled by your kidneys signaling to your body to do this by generating a specific hormone. After that happens, they're created in your body's bone narrow, the soft tissue inside your bones, and are released into your body's bloodstream from there.
During the approximately four months they're alive, the red blood cells play a major role as an oxygen -transportation system for your body. Inside of your red bloods cells is a protein known as hemoglobin.
It's why your blood appears red and helps make sure that the oxygen in the air you breathe reaches the rest of your body. The spleen continuously destroys millions of old red blood cells, recycling the iron to make new red cells. White blood cells leukocytes , help your body fight off infections. There are different types of them that fight off germs , help with blood clotting, and destroy bacteria that shouldn't be in your body. The majority of them are also generated in your bone marrow.
Platelets thrombocytes are, just like red blood cells and most of your white blood cells, generated in your bone marrow. When you have, for example, a cut, they work to help your body regulate the flow of bleeding when possible and begin the healing process at the source of the room.
So, how does bone marrow do all this? Plasma is a pale yellow mixture of water, proteins and salts. One of the functions of plasma is to act as a carrier for blood cells, nutrients, enzymes, and hormones.

Think of your blood as a fruit smoothie made up of about four basic ingredients blended together, all of them important: Red Blood Cells White Blood Cells Platelets Plasma Blood cells are produced in the marrow of bones, especially the vertebrae, ribs, hips, skull and sternum.
Red Blood Cells - erythrocytes Red blood cells are disc-shaped cells containing hemoglobin, which enables the cells to pick up and deliver oxygen to all parts of the body, then pick up carbon dioxide and remove it from tissues. Make up about 40 percent of your blood.
Carry oxygen from the lungs to tissue, and carry back carbon dioxide to the lungs. Contain the molecule hemoglobin which carries the oxygen and makes blood red. Live about days and are removed by the spleen. Have an after-donation shelf life of days.
Most needed for patients with significant blood loss through trauma, surgery, or anemia. The mainfunction of red blood cells is to carry oxygen from the lungs to the body tissues. And to carry carbon dioxide as a waste product away from the tissues and back to the lungs. Hemoglobin is an important protein in red blood cells that carries oxygen from the lungs to all parts of our body. The main function of white blood cells is to fight infection.
There are several types of white blood cells. Each has its own role in fighting bacterial, viral, fungal, and parasitic infections. Types of white blood cells that are most important for helping protect the body from infection and foreign cells include the following:. Help heal wounds.
They do this by fighting infection, and also by taking in matter, such as dead cells, tissue debris, and old red blood cells. Are our protection from foreign bodies that enter the blood, such as allergens. Help to protect against changed mutated cells, such as cancer.
The main function of plateletsis blood clotting. Platelets are much smaller in size than the other blood cells. They group together to form clumps, or a plug, in the hole of a vessel to stop bleeding. What is a complete blood cell count CBC? A complete blood cell count CBC is a measurement of size, number, and maturity of the different blood cells in a specific volume of blood.
A CBC can be used to determine many abnormalities with either the production or destruction of blood cells. Changes from the normal number, size, or maturity of the blood cells can be used to show an infection or disease process.
Often with an infection, there will be a highernumber of white blood cells. Many forms of cancer can affect the bone marrow production of blood cells. An increase in the immature white blood cells in a CBC can be linkedto leukemia. Anemia and sickle cell disease will have abnormally low hemoglobin.
