Sometimes it often crosses your mind how blood is produced in the body?

– Blood is the vital fluid that circulates through your body, delivering oxygen and nutrients to your cells and removing waste products.

– Blood is produced in your bone marrow, the soft and spongy tissue inside your bones. Bone marrow contains stem cells, which are immature cells that can develop into different types of blood cells: red blood cells, white blood cells, and platelets. Each type of blood cell has a specific function and lifespan in your body.

– Red blood cells, or erythrocytes, are the most abundant type of blood cell. They carry oxygen from your lungs to your tissues and carbon dioxide from your tissues to your lungs. They contain a protein called hemoglobin, which gives blood its red color and binds to oxygen. Red blood cells live for about 120 days and are constantly replaced by new ones.

– White blood cells, or leukocytes, are part of your immune system and help fight infections and diseases. There are five types of white blood cells: neutrophils, eosinophils, basophils, lymphocytes, and monocytes. Each type has a different role in defending your body from foreign invaders, such as bacteria, viruses, fungi, and parasites. White blood cells have a variable lifespan, ranging from a few hours to several years.

– Platelets, or thrombocytes, are small cell fragments that help stop bleeding and heal wounds. They stick to damaged blood vessels and form a plug that seals the injury. They also release clotting factors that trigger a chain reaction that results in the formation of a fibrin clot. Platelets live for about 10 days and are constantly replaced by new ones.
