correct answer is: option d : Bone marrow
Explanation: In adult human beings, the formation of blood corpuscles, a process called hematopoiesis, primarily takes place in the bone marrow. The bone marrow contains stem cells that differentiate into various types of blood cells, including red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes). While other organs may play a role in blood cell formation during fetal development or in certain disease states, the bone marrow is the major site of hematopoiesis in adults.
- Option a: Liver: The liver is involved in the production of clotting factors and the metabolism of red blood cells but it is not the primary site of blood cell formation in adults.
- Option b: Spleen: The spleen filters blood, stores white blood cells, and removes old or damaged red blood cells. It can produce blood cells in certain diseases, but is not the major site in healthy adults.
- Option c: Heart: The heart is a muscular organ that pumps blood throughout the body. It is not involved in the formation of blood cells.
