It is 2 million every second so in an hour it's a very large number -- 6,400,000,000 or six billion two hundred million

The average human body has about 5 liters (1.3 gallons) of blood. The heart pumps about 5 liters of blood every minute, so that would be around 300 liters (79 gallons) of blood per hour.
The shortest lifespan among cells is typically seen in white blood cells, specifically neutrophils, which have a lifespan of about 1-2 days. These cells are constantly being produced and eliminated as part of the immune response.
Cells in the human body are constantly changing through processes such as cell division, growth, and repair. The rate of cell turnover varies depending on the tissue type and age, with some cells turning over rapidly (like skin cells) and others more slowly (like neurons). Overall, the turnover of cells helps to maintain the health and function of our tissues and organs.
The process you are describing is called erythrocyte sedimentation rate (ESR) testing. It measures how quickly red blood cells settle at the bottom of a vertical tube of blood, usually over the course of one hour. This test can provide information about inflammation levels in the body.
New fresh blood cells can be formed in under 24hours. Some people have it good and they produce blood in about an hour, not a whole lot but enough to replace the blood you would lose if you got a cut and lost a lot.
Every hour
Of course there is no set number, but they have trillions and trillions of cells, billions of them being replaced every hour.
To determine the number of cells after 24 hours, we need to know the initial number of cells and the growth rate (e.g., whether they divide every hour or every few hours). For example, if a single cell divides every hour (a common scenario in binary fission), after 24 hours, there would be 2^24 cells, which equals 16,777,216 cells. Without specific details on the initial number of cells or the growth rate, it’s impossible to provide an exact answer.
Islet cells, specifically the beta cells within the pancreatic islets, secrete insulin in response to rising blood glucose levels. While they do not secrete insulin at a fixed interval like every 6 minutes, they release it in a pulsatile manner, with bursts occurring several times per hour. This rhythmic secretion helps regulate blood sugar levels effectively. The exact timing and quantity can vary based on individual metabolic needs and conditions.
On average, a human sheds about 30,000 to 40,000 particles of skin every hour. This continuous shedding is a natural part of the skin renewal process, with old skin cells being replaced by new ones.
It is to see how well the heart is reacting to the new blood that has been put into the body. And vital signs are always checked whether they just received a blood transfusion or if it is just a regular doctors visit. Vital signs are very important!
Your cells split in half and multiply. (It may be every half and hour they split but you should probably check this). Your cells also die off.

On average, a man produces about 1,500 sperm cells per second, amounting to millions of sperm cells in a 24-hour period.
