The human body contains approximately 25 trillion to 30 trillion red blood cells (erythrocytes) at any given time, depending on factors such as age, sex, and overall health. Additionally, there are also millions of white blood cells (leukocytes) and platelets (thrombocytes) present in the bloodstream. In total, the number of blood cells in the human body can be estimated in the range of 30 trillion to over 40 trillion, including all types of blood cells combined.
