Facts About Blood and Blood Cells | Facts about blood cell production 

The average human adult has more than 5 liters (6 quarts) of blood in his or her body. Blood carries oxygen and nutrients to living cells and takes away their waste products. It also delivers immune cells to fight infections and contains platelets that can form a plug in a damaged blood vessel to prevent blood loss.,

Through the circulatory system, blood adapts to the body's needs. When you are exercising, your heart pumps harder and faster to provide more blood and hence oxygen to your muscles. During an infection, the blood delivers more immune cells to the site of infection, where they accumulate to ward off harmful invaders.

All of these functions make blood a precious fluid. Each year in the USA, 30 million units of blood components are transfused to patients who need them. Blood is deemed so precious that is also called "red gold" because the cells and proteins it contains can be sold for more than the cost of the same weight in gold.
 
Red blood cell (RBC) production (erythropoiesis) takes place in the bone marrow under the control of the hormone erythropoietin (EPO)..These blood-forming stem cells can grow into all 3 types of blood cells – red cells, white cells and platelets. These blood-forming stem cells make copies of themselves, and they also produce mature blood cells. RBCs are the most common type of cell found in the blood, with each cubic millimeter of blood containing 4-6 million cells. 

With a diameter of only 6 µm, RBCs are small enough to squeeze through the smallest blood vessels. They circulate around the body for up to 120 days, at which point the old or damaged RBCs are removed from the circulation by specialized cells (macrophages) in the spleen and liver.Blood cell formation, also called hematopoiesis or hemopoiesis, continuous process by which the cellular constituents of blood are replenished as needed
 
In humans, as in all mammals, the mature RBC lacks a nucleus. This allows the cell more room to store hemoglobin, the oxygen-binding protein, enabling the RBC to transport more oxygen. RBCs are also biconcave in shape; this shape increases their surface area for the diffusion of oxygen across their surfaces. In non-mammalian vertebrates such as birds and fish, mature RBCs do have a nucleus.

A low white blood cell count usually is caused by: Viral infections that temporarily disrupt the work of bone marrow. Certain disorders present at birth (congenital) that involve diminished bone marrow function. Cancer or other diseases that damage bone marrow.

nutrients that increase red blood cell counts:
red meat, such as beef.
organ meat, such as kidney and liver.
dark, leafy, green vegetables, such as spinach and kale.
dried fruits, such as prunes and raisins.
beans.
legumes.
egg yolks.

People also ask

How is blood cell production?

Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.

What does the blood cell produce?

Red blood cells are responsible for transporting oxygen from your lungs to your body's tissues. Your tissues produce energy with the oxygen and release a waste, identified as carbon dioxide

How many blood cells produced a day?

The rate of blood cell formation varies depending on the individual, but a typical production might average 200 billion red cells per day, 10 billion white cells per day, and 400 billion platelets per day.

What is blood cell production called?

Most blood cells are made in your bone marrow. This process is called haemopoiesis.

Where are blood cells produced?

Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones. It produces about 95% of the body's blood cells.
