Blood is circulating throughout the entire body every minute of the day. Blood is composed of three components: red blood cells, white blood cells and platelets. Red blood cells are responsible for carrying the oxygen to the body and carbon monoxide and other wastes out of the body. A white blood cell is part of the immune system that will attack foreign particles. Lastly, the platelets are responsible for clotting. When someone has hemophilia the platelets in the blood do not react the way they should and will cause slow or no clotting of the damaged area.
Approximately 200-250 billion red blood cells are produced and destroyed per day in a healthy adult. This balance is important to maintain the body's red blood cell count and overall health.
13,000 Are produced in a day.
By using a centrifuge. I donate platelets, not whole blood and it is done by this method. They spin out what they need. whole blood donations can also be split to help as many as three different patients. You can't derive blood from plasma. You can derive plasma from blood all day long, but you can't derive a whole (blood) from a part (plasma).
Low platelet count leads to petechial hemorrhages. They can be seen at the hair roots. Later on you can have bleeding gums and bleeding through your nose. There can be vomiting of blood and bloody diarrhoea.
Bone marrow is responsible for producing white blood cells, along with red blood cells and platelets. White blood cells are essential for the body's immune response, as they help fight off infections and foreign invaders. The bone marrow contains stem cells that can differentiate into various types of white blood cells to support the immune system.
The rate of blood cell formation varies depending on the individual, but a typical production might average 200,000,000,000 red cells per day, 10,000,000,000 white cells per day, and 400,000,000,000 platelets per day.

A normal healthy person has about 6 liters of blood and makes 25 -30 ml every day so would make a complete new pool of blood ever 200 or so days. You can make the blood faster if needed. Within the "blood" total the red blood cells last about 120 days, platelets about a week and white blood cells a few hours to days for the most common types (but years for some types).

To calculate the number of new red blood cells that must be produced per second to replace the RBC population, you would need to consider the total number of red blood cells in the body and their lifespan. Given that an average adult has 5 liters of blood (which is equivalent to 5,000,000 microliters) and each microliter contains 5 million red blood cells, you would multiply these values to find the total number of red blood cells in the body. Then, you would divide this total by the 120-day lifespan of red blood cells to determine how many cells need to be produced each second.
Platelets are cells in your blood that help blood to clot. They are made in the bone marrow. Chemotherapy can cause your bone marrow to make less platelets and may make you prone to bruising or bleeding.A count of 129,000 (or referred to as 129 for short) on treatment day is probably fine to proceed with chemotherapy. There are many factors to consider including type and dose of chemotherapy. Talk to your doctor about how your chemo regimen affects your platelet count.
