How many red blood cells does the bone marrow produce every second?
The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.

Hematopoiesis is the production of all types of blood cells including formation, development, and differentiation of blood cells. Prenatally, hematopoiesis occurs in the yolk sack, then in the liver, and lastly in the bone marrow. In the normal situation, hematopoiesis in adults occurs in the bone marrow and lymphatic tissues. All types of blood cells are derived from primitive cells (stem cells) that are pluripotent (they have the potential to develop into all types of blood cells).

Red blood cells or erythrocytes are mainly used to deliver oxygen (O2) to the blood tissues through the blood flow with the help of circulatory system. Approximately. 2.5 million new rbc's are produced/second in an adult human body. These cells are developed by bone marrow which is the largest bone used in developing or producing the cells. These cells circulate for about 100-120 days in the body. Hope at least I have provided an insight to the queries. Thank you.

Bone marrow (Latin: medulla ossium) is the flexible tissue found in the interior of bones. In humans, bone marrow in large bones produces new blood cells. On average, bone marrow constitutes 4% of the total body mass of humans; in adults weighing 65 kg (143 lbs), bone marrow accounts for approximately 2.6 kg (5.7 lbs). The hematopoietic(stem cells) compartment of bone marrow produces approximately 500 billion blood cells per day, which use the bone marrow vasculature as a conduit to the body's systemic circulation.Bone marrow is also a key component of the lymphatic system, producing the lymphocytes that support the body's immune system.
